Api and Hthp Fluid Loss Test

Api Fluid Loss Test (low-pressure, low-temperature filtration test) is a test to portion a filtration of mud with ambient temperature and 100 psi differential pressure. The Api testing tool is shown below.

How will you test the drilling mud?

"Differential Pressure"

  • Place a filter
  • Add the sample in the testing chamber
  • Place the accommodation in the testing kit
  • Apply 100 psi pressure
  • report volume for 30 minutes at the end of the test the volume of filtrate will be recorded.
  • report thickness of filter cake

If the drilling mud has good fluid loss property, you will get a thin and an impermeable mud cake. Please keep in mind that this test is based on the outside condition, and it may be error because it does not simulate downhole conditions. The Api fluid loss test can lead you to the wrong conclusion because at the outside condition, the test demonstrates very good fluid loss and very thin filter cake. When the drilling mud is in downhole condition, wellbore temperature and pressure will change the fluid property dramatically. The best way to test the fluid loss is to simulate wellbore temperature and pressure, and it will be discussed in the Hpht fluid loss later.

Hthp Fluid Loss Test

First of all, I would like to tell you about what Hthp stands for. Hthp stands for High Pressure High Temperature. The Hthp test is similar to the Api test because it tells us about drilling mud filtration into the formation under a static condition over inescapable period of time. For the Hthp test, you can vary both temperature and pressure to describe your improbable downhole condition. The Hthp testing tool has a heating jacket so you can heat up the drilling fluid sample to the improbable wellbore temperature. Typically, the recommended temperature in the heating jacket should be above the estimated temperate about 25F to 50F. You don't want the testing temperature too high or low because it will not describe downhole condition very well. Therefore, with the recommended temperature, the drilling mud will not be over or under treated. Moreover, while performing the test, it must be under pressure and the test should be conducted at 500 psi differential pressure. The Hthp test is performed for 30 minutes, like the Api fluid lost test.

The impacts on drilling doing are listed below:

Formation damage - If the drilling mud does not have good fluid loss property, fluid with small particles in drilling mud can be invaded into formations causing the formation damage. If the well is severely damaged, it will not be able to furnish after perforation. This situation will heavily sway the profit of oil companies.

Differential sticking - The drilling fluid that has bad fluid loss will form a very soft and thick mud cake across the permeable formations. It can lead to differential sticking incident because the contact area between formation and drill string is increased.

Torque and drag - A thick mud cake across porous zones can be really formed because the drilling mud has high fluid loss values. The thicker of mud cake is, the more torque and drag are experienced while drilling and tripping operation.

comprehension Your Oil Pressure Sensor is a Vital Part of holding Your Car wholesome

Oil pressure levels must be constantly monitored to ensure that your auto's motor is properly lubricated. With the help of the oil pressure sensor attached to the gauge, you can beyond doubt monitor even the slightest changes to the pressure of your oil. Technically, these sensors function to send a signal to the gauge on the car's dashboard when the oil pressure drops to requisite levels. In simple terms, these sensors are basically tasked to warn you of any drastic changes to the pressure level that is above or beyond the general range.

Since oil is a very important motor component that acts as a lubricant to prevent disagreement buildup, it is requisite that you ensure that there is sufficient oil gift in the motor to ascertain that its enchanting parts will be consistently lubricated. This is very important so that your motor will be able to run smoothly and efficiently and to prevent damage. On that note, make sure that you immediately replenish your motor with new oil every time your pressure gauge prompts low oil level readings.

Differential Sensors

The truth is monitoring your oil's levels is fairly a straight forward task. All you have to do is ordinarily check your dashboard to monitor your current oil pressure reading. To do that, you must first set baseline values, which will serve as guides, to know if the oil pressure level is beyond or below the general reading. You should be able to find your ideal oil pressure range in your owner's hand-operated and you will get to know your vehicle's general level over time. Typically, it is recommended that oil pressure levels must be kept within 20 to 60. Try to make it a habit to espy on your dashboard every now and then to ascertain that your oil pressure levels stay within the general range and don't ignore any sudden fall in readings.

Anytime you observation that the pressure of your oil is low, the pressure warning light is flickering or has come on, or you see that your pressure gauge has dropped considerably - do not keep driving. Park your car and sit and wait for the motor to cool a bit.

Then check the oil level by using the dipstick, after first wiping it on a rag. If the level is at or below the low level mark indicated on the dipstick then probably all you need to do is gently add fresh oil to bring it up to the full mark. When you start the motor again the light should no longer be on or it will go off after a few seconds. Now your only worry is if you have caused any damage to the motor by letting run low on oil. If you hear any strange knocking noises from the motor then the damage has already been done and you need to get your car to a mechanic or heal shop as soon as possible.

To wrap things up, retention your oil's pressure within the suitable levels will ensure that your car's motor will work on its optimum efficiency. Therefore, premise of a trustworthy oil sensor and gauge is a must to ensure this!

How to install an Oil Pressure Gauge

Basically, an oil gauge is used to indicate oil pressure levels. It is generally installed on the dashboard of a vehicle in order to help the driver to properly monitor the oil pressure levels. When the warning light on the gauge lights up, it is an indication that the oil pressure level in the engine is very low; hence it must be replenished immediately to avoid engine damage. That being said, the installation of an oil pressure gauge is very important.

In general conditions the needle on your oil pressure gauge will remain in the same position and you will become used to it being there. You need to be aware when the needle begins to move downwards as this will commonly happen long before the warning light comes on and gives you more time to prevent damage to your engine. If your car is more than a few years old, the gauge is indicating that your oil needs changing or that the usual wear and tear of age is beginning to happen. There may be a great deal of life left in your vehicle, but you will need to considered watch your oil level from today. If the needle dips wildly downwards and then back up to a general level, there may already be damage or a drastically low oil level. It can prove to be very high-priced to ignore the warning signs.

"Pressure Sensor"

pressure sensor mat

Installing an oil gauge so that you can keep an eye on your oil pressure is not the simplest task and is probably best carried out by a professional, but if you want to do it yourself here is some data that may help.

Whether you will be installing an electric or mechanical oil pressure gauge, it would be ideal that you know how to properly concentrate it into your vehicle system. To help you accomplish that, here is a detailed installation guide that you can follow:

Step one: It is significant that you know where to properly place the gauge. You should know that the port where the gauge must be located is commonly situated six inches behind the vehicle's oil filter. In order to in fact find the port, you may have to remove the side front wheel on the passenger's side. Once it has been removed, you will see a silver-colored filter (located behind the installation oil pressure switch) that has two wires attached to the electrical connector.

Step two: After locating the port, you have to first drain the oil before removing the electric connector present on the pressure switch.

Step three: Once done, you may now disconnect the switch. The rest of the course will depend on the type of gauge that you need to install. Normally, pressure gauges include an installation manual, which you have to considered read and understand, in order to ensure allowable installation.

Step four: When the oil gauge has already been installed, make a test run to know if it is already functional. If you are unsure that you did the right thing, it is best that you find a pro mechanic to do the installation for you.

group security Disability healing Consultations - How to Build Your Case

If the evidence provided by the claimant's own healing sources is inadequate to decree if he or she is disabled, supplementary healing facts may be sought by re-contacting the treating source for supplementary facts or clarification, or by arranging for a Ce. The treating source is the preferred source of purchased examinations when the treating source is qualified, equipped and willing to accomplish the supplementary exam or tests for the fee program cost and ordinarily furnishes unblemished and timely reports. Even if only a supplemental test is required, the treating source is ordinarily the preferred source for this service. Ssa's rules supply for using an independent source (other than the treating source) for a Ce or diagnostic study if: The treating source prefers not to accomplish the examination; there are conflicts or inconsistencies in the file that cannot be resolved by going back to the treating source; the claimant prefers another source and has a good infer for doing so; or prior palpate indicates that the treating source may not be a efficient source. The type of exam and/or test (s) purchased depends upon the definite supplementary evidence needed for adjudication. If an ancillary test (e.g., X-ray, Pfs or Ekg) will yield the supplementary evidence needed for adjudication, the Dds will not request or authorize a more wide examination. If the exam indicates that supplementary testing may be warranted, the supplier must palpate the Dds for approval before performing such testing. Fees for Ces are set by each State and may vary from State to State. Each State department is responsible for wide oversight supervision of its Ce program.

Selection of a Consultative exam Source

Differential Pressure Sensor Principle

The Dds purchases consultative examinations only from qualified healing sources. The healing source may be the individual's own doctor or psychologist, or another source. In the case of a child, the healing source may be a pediatrician.

By "qualified," we mean that the healing source must be currently licensed in the State and have the training and palpate to accomplish the type of exam or test we request. Also, the healing source must not be barred from participation in our programs. The healing source must also have the tool required to supply an adequate evaluation and narrative of the existence and level of severity of the individual's alleged impairments.

Medical professionals who accomplish Ces must have a good understanding of Ssa's disability programs and their evidence requirements. The doctor or psychologist chosen may use support staff to help accomplish the consultative examination. Any such support staff (e.g., X-ray technician, nurse, etc.) must meet standard licensing or certification requirements of the State.

Generally, sources are selected based on appointment availability, distance from a claimant's home and quality to accomplish definite examinations and tests.

Consultative exam narrative Content

The exam narrative should contain the claimant's claim whole and a corporal narrative of the claimant, to help ensure that the man being examined is the claimant.

The information and format for reporting the results of the healing history, corporal examination, laboratory findings, and conference of conclusions should consequent the standard reporting principles for a unblemished healing examination.

The narrative should be unblemished adequate to enable an independent reviewer to decree the nature, severity and duration of the impairment, and, in adults, the claimant's quality to accomplish basic work-related functions. The history and corporal exam must be provided as a narrative of the findings.

Conclusions in the narrative must be consistent with the objective clinical findings found on exam and the claimant's symptoms, laboratory studies, and demonstrated response to medicine and on all available information, including the history. The report, for adults, should contain a description, based on the provider's own findings, of the individual's quality to do basic work-related activities. It should not contain an belief as to whether the claimant is disabled under the meaning of the law.

Signature Requirements

All Ce reports must be personally reviewed and signed by the supplier who really performed the examination. The supplier doing the exam or testing is solely responsible for the narrative contents and for the conclusions, explanations or comments provided. The source's signature on a narrative annotated "not proofed" or "dictated but not read" is not acceptable. A rubber stamp signature or signature entered by another person, such as a nurse or secretary, is not acceptable.

How the Dds Reviews Consultative exam Reports

The Dds is obligated to spin the narrative of the Ce to decree whether the definite facts requested has been furnished.

The Ce narrative must:

Provide evidence that serves as an adequate basis for disability decision making in terms of the impairment it assesses.

Be internally consistent. Are all the diseases, impairments and complaints described in the history adequately assessed and reported in the clinical findings?

Do the conclusions correlate the healing history, the clinical exam and laboratory tests, and elaborate all abnormalities?

Be consistent with the other facts available within the specialty of the exam requested.

Did the narrative fail to mention an leading or relevant complaint within that specialty that is noted in other evidence in the file (e.g., blindness in one eye, amputations, pain, alcoholism, depression)?

Be adequate as compared to the standards set out in the course of a healing education.

Be properly signed.

If the narrative is inadequate or incomplete, the Dds will palpate the supplier and ask the supplier to yield the missing facts or get ready a revised report.

Elements of a unblemished Consultative Examination

A unblemished Ce is one that involves all the elements of a standard exam in the applicable healing specialty. When the narrative of a unblemished Ce is involved, the narrative should contain the following elements:

The claimant's major or chief complaint(s);

Detailed description, within the area of specialty of the examination, of the history of the major complaint(s);

Description, and disposition, of pertinent "positive" and "negative" detailed findings based on the history, examination, and laboratory tests associated to the major complaint(s), and any other abnormalities or lack thereof reported or found during exam or laboratory testing;

Results of laboratory and other tests (e.g., X-rays) performed in accordance with the requirements provided by the Dds.

Diagnosis and prognosis for the claimant's impairment(s);

Statement about what the claimant can still do despite his or her impairment(s), unless the claim is based on statutory blindness. This statement should spin the belief of the consulting doctor or psychologist about the claimant's ability, despite his or her impairment(s), to do work-related activities such as sitting, standing, walking, lifting, carrying, handling objects, hearing, speaking, and traveling; and, in cases of thinking impairment(s), the belief of the doctor or psychologist about the individual's quality to understand, to carry out and remember instructions, and to retort appropriately to supervision, coworkers, and work pressures in a work setting; and

The consultative doctor or psychologist will consider, and supply some explanation or comment on, the claimant's major complaint(s) and any other abnormalities found during the history and exam or reported from the laboratory tests. The history, examination, evaluation of laboratory test results, and the conclusions will represent the facts provided by the doctor or psychologist who signs the report.

Telemetry - How To pick The Right Telemetry law For Your company Requirements

Telemetry is a broad field and it is applicable to many dissimilar areas: from safety monitoring in nuclear plants, to the migration habits of endangered species. It is widely used in big projects like power plants, sewer operate and purifying water plants; and their versatility has found diverse applications in the private arena. Thanks to the advances in technology, telemetry is used successfully in chemical plants and the food industry; this used to be a challenge in the past as stainless steel and concrete interfere with some wireless signals.

Measuring of bodily and chemical parameters in tanks are areas where telemetry has huge applicability. Due to the diversity of configurations, there is not a one size fits all solution. When shopping for the best telemetry principles for your single firm requirements, you need to have a clear idea of your conditions beforehand. There are seven main elements complicated in the implementation of the system, if you elaborate your needs in these seven points, it will be very easy to pick the right configuration:

Differential Pressure Sensor Installation

Sensor/hardware optimization: The sensors to be used will be affected by the nature of the substance in the tank. It is not the same to have acid, fuel or syrup. So take note of what is in the tank.

Sensor integration: Depending on what you want the sensor to part and the conformation of your tanks, the best position to place it will vary. You also need to specify if you are using the principles for a single tank or many tanks. The main options for positioning in site are:

  • Flow meter: in or out
  • Bottom: differential pressure
  • Top: ultrasonic or contact
  • Contact: high, low or overflow

Form of communication/signal: The optimal form of transportation will be carefully by the location characteristics and accessibility of signal. The two main groups are short range wireless association or long range wireless connection.

Short range: If your tank is close to a Lan(Local Area Network) or a Wan (Wide Area Network), you can use low energy signals. Some of the options available are: 802.xx protocol, Wi-Fi and short haul Rf. Which one is the best depends on the obstacles in the signal´s path and their wave absorption power.

Long range: If the tank is in a remote place or the short range signals are absorbed, some of the options are digital mobile technology (Gprs/Cdma), analog cellular, satellite or a aggregate of them.

Power: The transportation devices need energy to operate. If your tank is local, pay concentration to the power configuration and see if you can hardwire or if you need a battery. If the tank is on a remote location, you can you use a battery or you might need solar charging.

Communication frequency/Direction of signal: The optimal transportation frequency will be consequence of the nature of the data you want to analyze and store; and if you want the principles to perform actions or not. If you are using telemetry for transmitting data to a central hub for safety or analysis, then you will need one way communication. If you want the principles to be able to answer to distinct signal and create changes (open/close a valve for example), you need two way communication.

Once you pick one or two way communication, there is still the actual transmission frequency. Some of the options are: continuous, minutely, hourly, daily, monthly or alarm activated (usually high or low level).

The transportation frequency and direction of signal will sway the choice of the emitter and receiver hardware, and partly the supervision software used or institution advanced for you.

Storage and supervision of information: If you have a Lanor Wam, you can store and run the prognosis of the data on your own network. In this case, at least one of the computers of the network will be dedicated to this endeavor, and the reception hardware will be attached to it. If, on the other hand, citizen from dissimilar geographical locations need entrance to the information, then you might opt for a hosted solution. Hosted solutions allow for 24-7 entrance via internet, so it becomes location independent.

Budget: There are hardware choices in dissimilar price ranges. As rule of the thumb, the smaller the up-front cost the bigger the long term cost. The total cost of the scheme will be given by the hardware itself, installation, life of the tool and maintenance costs.

These are the seven main elements to analyze when finding for a telemetry principles for your firm requirements. If you crusade for a service victualer with this data at hand, the crusade will be much more sufficient and you will be able to take informed decisions fast.

The Elements Of An productive Hvac system

Today's systems are designed to meet stricter environmental, indoor air capability and user requirements. Many of the gains in Hvac system efficiency have come as the ensue of improvements in the operating efficiency of key system components. Other gains are the ensue of the use of technologies that are whether new, or new to the Hvac field. Even the use of computer-aided found tools have helped system engineers found Hvac systems that perform more efficiently.

Although there are many private advances that have helped to heighten Hvac system operating efficiency, much of the wide improvement can be attributed to five key factors:

Differential Pressure Sensor

differential pressure sensor

- The amelioration of low kW/ton chillers;
- The use of high-efficiency boiler operate systems;
- The application of direct digital operate (Ddc) systems;
- The use of energy-efficient motors; and,
- The matching of changeable frequency drives to pump, fan and chiller motors.

For years, construction owners were satisfied with the carrying out and efficiencies of chillers that operated in the range of 0.8 to 0.9 kW/ton when new. As they age, actual operating efficiencies fall to more than 1.0 kW/ton at full load.

Today, new chillers are being installed with full load-rated efficiencies of 0.50 kW/ton, a near 50 percent increase. Equally impressive are the part-load efficiencies of the new generation of chillers. Although the operating efficiency of nearly all older chillers rapidly falls off with decreased load, the operating efficiency of new chillers does not drop off nearly as quickly.

Chiller found changes

Several found and carrying out changes have helped heighten chiller performance. To heighten the heat change characteristics of the chillers, manufacturers have increased the size of the units' heat exchangers. Electromechanical operate systems have been replaced by microprocessor-based electronic controls that provide greater precision, reliability and flexibility. changeable frequency drives operate the speed of the compressor, resulting in an growth in part-load performance.

Increased power efficiency is not the only advantage of the new generation of construction chillers; these chillers offer great refrigerant containment. Although older chillers routinely may have lost 10 percent to 15 percent of the refrigerant payment per year, new chillers can limit losses to less than 0.5 percent. Lower leak rates and great purge systems sell out the quantity of non-condensable gasses found in the refrigerant system -- a key factor in maintaining chiller carrying out over time.

Another requisite amelioration is in boiler operation: the change of pneumatic and by hand controls with microprocessor-based systems. As a rule of thumb, the systems can be staggering to perform power savings of 5 percent to 7 percent over conventional pneumatic-based systems.

Microprocessor-based operate systems perform their savings primarily as the ensue of their capability to modulate the boiler's carrying out more accurately than pneumatic-based systems. By modulating the boiler's carrying out accurately, the systems help to contend the permissible fuel-to-air ratio and track the load located on the boiler by the Hvac system.

Microprocessor-based systems offer any additional advantages, together with remote monitoring and operating capabilities, automatic operate sequences, monitoring of steam flow, and reduced maintenance costs. One way the systems can help sell out maintenance costs is through their capability to contend permissible fuel-to-air ratio. By maintaining the permissible ratio, the systems sell out the rate at which soot collects on boiler tubes, thus decreasing the frequency of required tear down and cleaning. Retention the boiler tubes clean of soot also helps to heighten the thermal efficiency of the boiler.

Direct digital controls

A major change in the Hvac field is the wide implementation of direct digital controls (Ddc). Introduced more than 15 years ago, Ddc systems have come to be the business thorough for operate systems found today. With the capability to provide literal, and literal, operate of climatic characteristic and air and water flows, the systems have widely replaced pneumatic and galvanic operate systems.

Ddc systems help construction owners save power in any ways. Their accuracy and precision nearly eliminate the operate problems of offset, overshoot, and hunting ordinarily found in pneumatic systems, resulting in great regulation of the system. Their capability to retort to a nearly unlimited range of sensors results in great coordinated operate activities. This also allows the systems to perform more involved operate strategies than could be performed with pneumatic controls. Finally, their simple or automatic calibration ensures that the operate systems will perform as designed over time, with minuscule or no loss of accuracy.

Ddc systems also offer any other advantages. Because the operate strategies are software-based, the systems can be of course modified to match changes in occupant requirements without costly hardware changes. Ddc systems also are ideal for applications that advantage from remote monitoring and operation.

Energy-efficient motors

Today's Hvac systems are making use of energy-efficient motors. Energy-efficient motors offer a moderate but requisite growth in full-load operating efficiency over thorough motor designs. For example, an energy-efficient 10 hp motor operates at about 93 percent efficiency; a thorough motor of the same size is typically rated at 88 percent. Similarly, a 50 hp energy-efficient motor is rated at approximately 94 percent efficiency in dissimilarity to the 90 percent efficiency rating of a 50 hp thorough motor.

This growth in operating efficiency accompanies a first-cost growth for the motors. How rapidly this additional first cost is recovered depends on two factors: the loading of the motor, and the amount of hours the motor is operated per year.

The closer the motor is operated to its full-load rating and the greater the amount of hours per year the motor is operated, the quicker the first-cost differential is recovered. For most applications where the motor is run continuously at or near full load, the payback period for the additional first cost is typically between three and six months.

The aggregate of constant loading and long hours of carrying out have made Hvac applications well-suited for the use of energy-efficient motors. Energy-efficient motors ordinarily are found driving centrifugal circulation pumps and system fans. With these loads, the 4 percent or 5 percent growth in the electrical efficiency of the drive motor translates to a requisite power savings, particularly when the systems operate 24 hours per day, year round.

A side advantage of energy-efficient motor found is its higher power factor. Expanding the power factor of a drive motor reduces the current draw on the electrical system, frees additional distribution capacity and reduces distribution losses in the system. Although Expanding the power factor isn't adequate of a advantage to explicate the cost differential of the higher efficiency motor, it's an leading consideration, particularly for large users of electricity where system capacity is limited.

Although the motors have demonstrated themselves to be very cost-effective in new applications, their use in existing applications is a minuscule more difficult to justify. In most instances, the cost to replace an existing, operating motor with one of higher efficiency will not be recovered for five to 10 years or longer.

Of the improvements in Hvac systems that have helped to growth operating efficiency, changeable frequency drives have had the most dramatic results. Applied to system components ranging from fans to chillers, the drives have demonstrated themselves to be very flourishing in reducing system power requirements during part-load operation. And with most systems operating at part-load capacities 90 percent or more of the time, the power savings produced by changeable frequency drives rapidly recover their investment, typically within one to two years.

In general, the larger the motor, the greater the savings. As a rule of thumb, nearly any Hvac system motor 20 hp and larger can advantage from the factory of a changeable frequency drive.

Variable frequency drive applications

Variable frequency drives produce their savings by varying the frequency and voltage of the motor's electrical supply. This dissimilarity is used to sell out the operating speed of the tool it controls to match the load requirements. At reduced operating speed, the power draw of the drive motor drops off rapidly.
For example, a centrifugal fan, when operated at 75 percent flow, draws only about 40 percent of full-load power. At 50 percent flow, the power requirement for the fan decreases to less than 15 percent of full-load power. While conventional operate systems, such as damper or vane control, also sell out the power requirements at partial flow, the savings are significantly less.

Another area where changeable frequency drives have improved the operating efficiency of an Hvac system is with centrifugal pumps found in hot and chilled water circulation systems. Typically, these pumps provide a constant flow of water to terminal units. As the request for heating or cooling water decreases, the operate valves at the terminal units throttle back. To keep the pressure in the system constant, a bypass valve between the provide and return systems opens. With the flow rate remaining nearly constant, the load on the pump's galvanic drive also remains nearly constant.

Variable frequency drives regulate the pressure in the system in response to varying demands by slowing the pump. As with centrifugal fans, the power required by the pumps falls off as the load and speed are decreased. Again, because most systems operate well below found capacity 90 percent of the time, the savings produced by reduced speed carrying out are significant, typically recovering the cost of the unit in one to two years.

Chiller loads

A third application for changeable frequency drives is centrifugal chillers. Chillers are sized for peak cooling loads, although these loads occur only a few hours per year.

With conventional operate systems that close vanes on the chiller inlet, chiller efficiency falls off significantly during part-load operation. When changeable frequency drives are applied to these chillers, they regulate the carrying out of the chiller by reducing the speed of the compressor. The ensue is near full-load operating efficiency over a very wide range of cooling loads. This growth in part-load efficiency translates into a 15 percent to 20 percent growth in the chiller's seasonal efficiency.

Energy conservation isn't the only advantage of changeable frequency drives. A strain is located on an galvanic motor and the mechanical system it drives every time a pump, fan or chiller is started at full-line voltage: Motor winding becomes heated, belts slip, drive chains stretch and high-pressure is advanced in circulation systems. changeable frequency drives sell out these stresses by beginning systems at reduced voltages and frequencies in a soft start, resulting in increased motor and tool life.

Finally, the most leading element in an energy-efficient Hvac system is how the system is operated. No matter how sophisticated the system, or how wide its energy-conserving features, the system's carrying out depends upon the way in which it's operated and maintained. Operating personnel must be properly trained in how best to use the system and its features. Maintenance personnel must be trained and qualified with the permissible tools to keep the system operating in the way it was designed. Maintenance cannot be deferred.

Energy-efficient Hvac systems offer the factory boss the capability to heighten system carrying out while reducing power requirements. But they advantage construction owners only as long as they are taken care of. If factory managers select to ignore maintenance requirements, they may soon find systems malfunctioning to the point where they have of course increased the requirement for energy.

Orifice Flow Meter

In this post, I am interested in covering the details about how to part flow using Orifice meter. And I am beginning it from the scratch.

Basic Principle

Differential Pressure Sensor Principle

When an orifice plate is settled in a pipe carrying the fluid whose rate of flow is to be measured, the orifice plate causes a pressure drop which varies with the flow rate. This pressure drop is measured using a differential pressure sensor and when calibrated this pressure drop becomes a part flow rate.

Description

The main parts of an orifice flow meter are as follows:

* A stainless steel plate which is held in the middle of flanges of a pipe carrying the fluid whose flow rate is being measured.

* It should be noted that for a positive distance before and after the plate fitted in the middle of the flanges, the pipe carrying the fluid should be level in order to maintain laminar flow conditions.

* Openings are provided at two places 1 and 2 for attaching a differential pressure sensor (U-tube manometer, differential pressure gauge etc).

Operation

* The detail of the fluid movement inside the pipe and orifice plate has to be understood.

* The fluid having uniform cross section of flow converges into the orifice plate's opportunity in its upstream. When the fluid comes out of the orifice plate's opening, its cross section is minimum and uniform for a singular distance and then the cross section of the fluid starts diverging in the down stream.

* At the upstream of the orifice, before the converging of the fluid takes place, the pressure of he fluid (P1) is maximum. As the fluid starts converging, to enter the orifice opportunity its pressure drops. When the fluid comes out of the orifice opening, its pressure is minimum (P2) and this minimum pressure remains constant in the minimum cross section area of fluid flow at the downstream.

* This minimum cross sectional area of the fluid obtained at downstream from the orifice edge is called Vena-Contracta.

* The differential pressure sensor attached in the middle of points 1 and 2 records the pressure dissimilarity (P1 - P2) in the middle of these two points which becomes an indication of the flow rate of the fluid straight through the pipe when calibrated.

Applications

1. The concentric orifice plate is used to part flow rates of pure fluids and has a wide applicability as it has been standardized.

2. The eccentric and segmental orifice plates are used to part flow rates of fluids containing suspended materials such as solids, oil mixed with water and wet steam.

Advantages

1. It is very cheap and easy method to part flow rate.

2. It has predictable characteristics and occupies less space.

3. Can be use to part flow rates in large pipes.

Limitations

1. The vena-contracta distance depends on the roughness of the inner wall of the pipe and sharpness of the orifice plate. In positive cases it becomes difficult to tap the minimum pressure (P2) due to the above factor.

2. Pressure saving at downstream is poor, that is, unabridged loss varies from 40% to 90% of the differential pressure.

3. In the upstream straightening vanes are a must to gather laminar flow conditions.

4. Gets clogged when the suspended fluids flow.

5. The orifice plate gets corroded and due to this after sometime, inaccuracy occurs. Moreover the orifice plate has low bodily strength.

6. The coefficient of extraction is low.

Wind Anemometers - How to part Wind Speed Accurately

For a science that is constantly in the lives of daily folk, wind speed determination absolutely manages to keep out of the social eye. The measuring of wind speed happens to be an leading part of a number of daily technologies. Of course there is meteorology, the measuring of weather phenomena, that fully depends on the gauging of wind speed; but a surprising number of other daily specialties depend on wind speed measurements too, chief among them being aviation and marine and navigation, stability supervision in skyscrapers, environmental sciences and disaster management. Wind determination is done with a device known as a wind anemometer; though it might be argued that that is a redundancy since anemometer comes from the Greek Anemos = wind.

Any device that measures wind speed is bound to sense the pressure of it too. For this reason, many anemometer designs are prosperous when used as pressure meters too in addition. A version of anemometer is known to have existed since around 1450. The modern wind anemometer though, has been around for more than a century and a half now; the first prosperous develop was one that used a structure with four arms fanned out, each one with a cup attached that caught the wind and spun the structure. The inventor, Dr. John Robinson, held the impression when he made his invention that any cup anemometer would share the characteristic that it would spin at a third of the speed of the wind blowing past it, no matter what size it was built to be. Researchers took his word at its face for quite a while before it was discovered that the size of develop used all the time affected the results. Researchers who had used the inventor's figures for their calculations for years had to start over from scratch.

Differential Pressure Sensor Principle

Cup anemometers, these straightforward devices, are remarkably strict machines today nevertheless; the best examples can approach a 99% accuracy level, and still be no more high-priced than about 00. But the cup anemometer is still a mechanical technology that is prone to maintenance lubrication issues, friction, mechanical damage and ice formation. There are contentious technologies that exertion to eliminate the problems seen in the mechanical design. One of the most favorite wind anemometer technologies in use today is the ultrasonic kind. The principle of the ultrasonic develop is this: the speed of sound depends on the speed and the direction of the air that it passes through. A headwind slows sound down, and a tail wind speeds it up. An ultrasonic wind anemometer fires high-frequency sound pulses back and forth between two receivers. If the pulse takes more time travelling in one direction than the other, that is a sign that the slower trip had a headwind working against it. The time differential helps guess the wind speed. You'll find these in use on tall buildings, on weather buoys and at weather stations.

Another wind anemometer develop that is particularly ingenious is the constant-temperature anemometer. A thin wire held between two electrodes is heated up electrically to hold a constant temperature. A sensor measures the number of current needed to hold the climatic characteristic at ambient climatic characteristic levels. Any loss of climatic characteristic that is faster than would be explained by the ambient climatic characteristic levels would have to come from wind speed. This is a particularly strict method of determination of wind turbulence. However, like the laser determination method below, this can be a quite reasonable device to buy and maintain.

Ultrasonic and constant climatic characteristic anemometers may be strict enough for most purposes; but laser Doppler anemometers offer extremely tight accuracy. A laser anemometer uses two laser beams; one that travels through a sealed and clean pathway, and one that travels through exposed air. The beam that travels through the exposed air encounters dust particles that are borne along at the speed of the wind at the point. The laser bounces off those dust particles, and measures by Doppler shift the speed at which the particle has been traveling. The Doppler shift is compared to what is measured for the beam traveling through the sealed tube and a relative determination is made.

It would appear from these descriptions that anemometers all the time need to be large and permanent installations; as it happens though, small and reasonable handheld versions with digital displays exist for use by field researchers and teacher pilots. The most stunning highlight of these is the way they recognizably use nothing other than the same mechanics and structures of the expert devices, only miniaturized for handheld use.

Faq on Modifying the Toyota Supra

What does Bpu(Tm) stand for? (Bpu(Tm) is a trademark of SupraStore.com)

Basic execution Upgrades. These modifications are: A full length three inch down-pipe (with or with-out high flow cats), 3" (75mm) or bigger cat-back exhaust system, raised boost (18psi), and the required boost cut eliminator (Greddy Bcc) needed to achieve that boost without activating the factory fuel cut-off at 14-15psi. These are the modifications that have proven to provide the best Hp-to-$$$ ratio.

Differential Pressure Sensor Circuit

What does the + mean when someone says Bpu(Tm)+? And what is Apu?

That stands for any additional power producing modifications other than the basic Bpu(Tm) modifications. One "+" refers to Adj. Cam Gears and under-drive pulleys, the second "+" refers to a Fuel controller, Ecu upgrade, etc. For instance, a Supra with the Bpu(Tm) modifications, plus a front-mount intercooler, would be called Bpu(Tm)+. If you added cam gears to that, it would be Bpu(Tm)++, and so on. The "Bpu(Tm)" term is used until you have an upgraded turbo(s). Then it is referred to as Apu, advanced execution upgrades. This designation pretty much covers every modification that can be performed.

What are the first machine modifications I should perform?

I recommend starting with raising the boost of the stock turbos to almost 18psi. This will need a potential boost gauge and a boost cut eliminator (Greddy Bcc). You will achieve 15 or so Psi with the stock Down Pipe in place. This will provide an increasing of almost 30rwhp. After those modifications are completed, it would be a logical next step to setup the Down Pipe and Cat-Back Exhaust at the same time. You will now be at full Bpu(Tm).

What do all the assorted "Free Mods" do?

There are many dissimilar "free mods" for the Supra Tt. I will cover just a few of them here. The ones I will cover fall into three categories, boost control, Egr disabling, and Ttc or True Twin Conversion.

Three of the boost control mods are: Bleeder-T Mod, Clamp Mod, and the Vsv Bypass Mod. Each of these modifications raise boost levels without the use of a boost controller. But you have to keep a close eye on your boost gauge, and make sure they are not allowing the turbos to boost too high (18psi is a safe level).

The next mods, are the true twin conversion mods (or Ttc). This modification disables the Sequential twin turbo operation, and causes the turbos to run permanently in parallel (both on at the same time). This is supposed to allow for slightly great mid-range power (before the secondary turbo would usually come online) and allows for a smoother power band, without the abrupt boost growth caused by the transition from former to secondary operation. However, this does noticeably decrease low-end power, and increases exhaust noise levels, and therefore may not be desirable on the street. Two types of the Ttc mod are, the former Ttc mod which includes 2 methods, wiring the actuators, or installing a one way valve, and the Electronic Ttc mod (Ettc).

The last mod I will discuss is the Egr mod. This disables the Exhaust Gas Recirculation system, which is meant for emissions, and therefore, this modification is for off-road use only. This mod is supposed to forestall the super heating of the estimate 5 and 6 cylinders, which may cause burnt valves.

How much power will my car make at Bpu(Tm)?

It varies from car-to-car, and the conditions as well as tuning. Most Bpu(Tm)-only Supra Twin Turbos, dyno between 370 and 410 horsepower at the rear wheels. This is usually achieved with moderate temperatures, a reset Ecu (to erase whatever bad the Ecu may have learned), and often a wee bit of high-octane un-leaded race fuel. On the street, power will be reduced, especially in poor weather, but at least 90 percent of the power should be retained.

What kind of 1/4 mile Ets and trap speeds should I run at Bpu(Tm)-only?

It varies Widely depending on driver skill. As well as track conditions, elevation above sea level, ambient temperatures, humidity, and pre-race preparation. But most fall between 12.3 to 12.9 ets with 112 to 119mph trap speeds on road tires. Times can drop well into the 11s with drag radials, a good driver, and good conditions, as well as proper pre-race preparation.

What is a Bpu(Tm)'d Supra Tt's top speed?

Speeds in the mid-high 180mph range should be achievable. Once the speed-limiter is disabled, by pulling the "Trac" fuse of course.

Will the life of my machine and Drivetrain be adversely affected with the Bpu(Tm) mods?

Yes, but not by a valuable amount. If the car is maintained properly, and the car is treated with some respect for the components, you should maintain much of the power train's life. Which considering the fact that the Supra is by far one of the most dependable and durable sports cars, it will last longer than most well maintained Stock sports cars. The only Drivetrain components that will see a significantly shortened life will be the stock clutch. It will more than likely not last much longer than 8-10k miles once at Bpu(Tm). This especially holds true if the car is making repeated high speed runs using 5th and 6th gear at wide open throttle. If your stock clutch has high mileage on it, or is already starting to slip, you will need to plan on a new high-performance clutch. Also the stock turbos will be subject to a somewhat shortened life span (how short will depend on how you drive and maintain the car, as well as how much boost you will run)

What's the reliability of a 600hp Supra Turbo?

Chassis, electrical, and suspension components should see wee succeed on reliability on road driven Supras. The stock 2Jz-Gte machine should hold up pretty well to this power level. Just how long depends on maintenance, and how hard you drive it, and how often. But typically Supras can go for years at this power level. The transmission reliability will depend on either it's an automated or Manual. A stock automated will not hold this much power, a built transmission will be required, and it's reliability will depend on it's found and construction. The 6spd manual should hold up just fine, as well as the rear differential and axles.

The only real reliability concerns at these low power levels would surround the actual modifications you perform. Excluding factory short-comings, the components utilized, even very high potential ones, may fall short of factory component reliability, as the built in compromises that exist in everything, would lean more towards the side of extreme performance, than of extreme reliability (Keep in mind we are talking about a Toyota here, whose reliabilty standards are exceptionally high) This may include fuel system components, turbo components, and especialy electronic wizardry. Basically a set-up that is either Very well concieved, or utilizes Oe components as much as possible, without over burdening them, would posses *near* stock reliability. And tuning of the components, and component selection, and matching, would play a Huge role in this.

What are the power limits of the assorted factory components (Differential, Transmission, Motor, etc.)?

There have de facto not been enough failures to de facto pin point a limit for the assorted power-train components. The motor could fail at factory power levels if it was running dangerously lean. But when well tuned, the motors internals (Pistons, Rods, Crank, Head Gasket etc) are dependable to 700rwhp. But of procedure at these power levels, if the machine is not set-up and tuned properly, it is de facto a bomb waiting to go off, any way this would be just as true with a built motor. Some owners have pushed their stock internals to the limit and have well exceeded 800rwhp, and even approached 900rwhp. I still don't understand how such an over built motor made it past the bean counters at Toyota Corporate.

The 6-speed Getrag is ridiculously strong for an Oe transmission. Its limit's will be affected greatly by driving technique, such as launching, and either or not power shifting is used. Even driven hard, the Getrag should hold up reasonably well with 700Rwhp. If you treat it with some respect, it should be able to handle around 800Rwhp or more, although great care and respect will need to be practiced at those levels.

Differential, axle, Cv Joint, and drive shaft failures are a Very rare occurrence. So I don't have much info on their failure limits. On road tires, it would be almost impossible to break any of these components at Any power level. The tires would spin before they would put the driveline under that kind of strain. The tires act sort of like a circuit breaker. If you run drag slicks, this does not hold true of course, yet they have proven themselves to be 10 and even 9 second capable.

Will drivability, interior noise levels, and low-end power be adversely affected with the Bpu(Tm) mods?

Drivability is not adversely affected. Interior noise level depends on the exhaust system you choose. Some will make it far louder; some will de facto make it quieter. But most are just a wee bit louder than stock. But the added dBs are also combined with a Much sweeter exhaust note, so it's certainly worth it. And the interior of the Supra is pretty quiet anyway, so on the highway, it will be Very livable. As far as low-end power goes, the down-pipe will greatly decrease Turbo Lag. So low-end power and response is much improved over stock.

Will emissions be adversely affected by the Bpu(Tm) mods?

As long as a high-flow cat is used, emissions should not be effected, and you should still pass visual inspection. If you run without catalytic converters, you are doing so at your own risk, and you would not pass visual or emissions testing.

Will fuel mileage be adversely affected by the Bpu(Tm) mods?

If driven calmly, as in light throttle, mileage should not be significantly affected. Mileage will greatly decrease while however, if you drive "vigorously", more power equals more burned fuel I am afraid.

Should I setup an "Intake" (Open Element Filter)?

This is a bit of a yes and no answer. The stock filter assembly is a flow restriction, and an open element intake would growth potential flow. However, it will also draw in more heated machine compartment air, which can hurt performance. My guidance is to either modify the stock filter box, or setup a cool air induction box, like the Max Air. An added bonus of the open element filters, is that they allow you to de facto hear the former turbo and by-pass valve.

What about the stock intercooler?

The stock intercooler does a decent job up till about 17psi on the stock turbos, after that you would probably observation a valuable gain, especially in warmer temperatures, with a nice front mount intercooler. However, keep in mind it will block some of the airflow to the radiator, as well as decreasing response slightly.

Should I replace the factory rubber Intercooler hoses with aftermarket metal hoses?

It wouldn't hurt. But it won't help a lot either. At the most you may slightly growth throttle response, but at least it will look nicer.

What about the fuel system, are the stock injectors and fuel pump large enough for Bpu(Tm)?

Yes, the stock fuel system is very safe and dependable to 450Rwhp, although I would recommend a fuel pulsation damper bypass. whatever over that, and I would highly recommend having the car dyno'd, and using a wide-band O2 sensor (not a cheap A/F gauge associated to the stock O2) to check the fuel ratio at your high boost setting. 11.5:1 would be a safe fuel ratio.

What are the stock injectors rated at?

540cc/min

Would the Supra benefit from a fuel controller?

Bpu(Tm)'d Supras run a wee on the rich side as far as fuel ratios go. This hurts power. What it does do is provide a safety margin that makes machine damage straight through detonation unlikely. If you get a fuel controller, and tune it properly (on a dyno, with an literal, Egt gauge, and a high band O2 (The Stock O2 sensors are not accurate), then you should be able to gain a noticeable estimate of power. One of the most favorite electronic fuel controllers is the A'Pexi S-Afc. The Fields Sfc is good too.

What should I use to growth my boost level, an Electronic Boost Controller, or a manual Bc?

Using an Ebc is the safest way to raise boost, it will forestall spiking and over-boosting. But it de facto comes down to your budget. If you can afford an Ebc, get one. If you can't, go with a Mbc. And always keep an eye on that boost gauge. And whatever you are using to control boost, remember to not get carried away, I don't recommend going usually over 18psi.

What is the best Electronic Boost Controller?

There de facto is no Best. Although the A'Pexi Avc-R is a nice unit, it provides much more control over boost than other Ebcs, but it is also more involved to install, and tune. The new Blitz unit is also nice. Most of the large manufacturers make decent units. Just avoid fuzzy-logic qualified models if you still have the sequential stock turbos, they will come to be "confused" by the unnatural behavior of the sequential system.

When installing my Ebc, do I join together it to both of the Turbo's Wastegates?

The former Turbo is the only one with a wastegate. When in full twin turbo mode, the boost of both Turbos is regulated by the former turbo's wastegate. So, only join together it to the Primary's.

Some habitancy say I need to replace my Ecu with a reprogrammed one, instead of just using a boost controller. Do I?

Reprogrammed Ecus for the Supra Tt are Very $$$. They are in the 00 range. And they have not been proven to provide a valuable growth in execution or safety on Bpu(Tm) level cars. Their merit shows itself on cars with upgraded Turbo(s). Just be sure you buy your Ecu, or have it reprogrammed by a reputable shop that knows what they are doing. And have it tailored to your singular car (Driving habits, and Mods). And I would also recommend taking a look at the Aem Programmable system.

What is a safe boost level to run at Bpu(Tm)?

The normal consensus is 17-18psi. Some habitancy have taken it higher, but I don't recommend it if you don't have the money for a turbo replacement/upgrade.

Which Down-Pipe is recommended?

The Rmm (or Rod Millen Motorsports) Cat-less Downpipe is the most generally used. any way many other brands exist. Some down-pipes, such as the Random Technology Dp, feature an emissions legal high-flow catalytic converter.

Will a high-flow cat hurt performance?

It will have some succeed on power output, but not a lot. Its exact succeed on Hp is not clear, but it probably costs a few hp at the most, maybe 5-15hp at Bpu(Tm) power levels.

What is a Down-Pipe?

It is the section of the exhaust system that connects the outlet of the Turbocharger's Turbine section to the "Cat-Back" exhaust system. The Downpipe is also where the two catalytic converters are located, as well as the O2 sensor (or sensors in Obd-Ii cars).

I have an Obd2 car. Can I still setup a Down-Pipe?

Yes. But unless the Dp has a Catalyst and a second location for an O2 sensor, you will trip your check machine light, unless you get one of those O2 "black boxes".

Which Exhausts are the loudest?

The Tanabe Racing Medallion, and Hks Hiper Titanium seem to be the two loudest systems.

Which Exhausts are the quietest?

The Tanabe Hyper Medallion, the discontinued Tanabe G-Power Medallion and the Greddy (Sp) road execution seem to be the quietest. At whatever less than full throttle, they are no louder than stock. But at full throttle they seem to "wake up" a bit.

What are some recommended exhaust systems?

It depends on your personal preferences. Below I will break down some of my recommendations based on inescapable combinations of preferences.

Subtle Styling / Very Low Cost:

-Random Technology (75mm, full stainless steel)

Subtle Styling / Low Sound Level / Moderate Cost:

-Greddy road execution (80mm)

-Tanabe Super Hyper Medallion (80mm, full stainless steel, 50-state legal)

Subtle Styling / Moderate Sound Level / Moderate Cost:

-Atr (75mm, full stainless steel)

Tasteful Styling / Low-Moderate Sound Level / Low Cost:

-Hks Dragger Ii (85mm)

Tasteful Styling / Low-Moderate Sound Level / Moderate Cost:

-Greddy Power extreme (80-94mm)

-Hks Super Dragger (95mm)

Tasteful Appearance / Moderate Sound Level / High Cost / Super Light:

-Veilside Tear Drop Titanium (90mm, full titanium)

Tasteful-Wild Styling / Low Sound Level / Moderate Cost:

-Trd 2nd gen.

Wild Styling / Moderate Sound Level / Low Cost:

-A'Pexi N1

-Hks Hiper (75mm)

Wild Styling / Moderate Sound Level / Moderate Cost:

-A'Pexi Gt Spec (95mm, full stainless steel)

-Blitz Nur Spec (80mm, full stainless steel)

-Hks Hiper Carbon/Titanium (75mm, Cf wrapped muffler, titanium tip)

Wild Styling / High Sound Level / Moderate Cost:

-Tanabe Racing Medallion (80mm, 50 state legal)

Wild Styling / High Sound Level / High Cost / High Flow:

-Hks Hiper Titanium (104mm, titanium muffler)

What is the cheapest route to replacing the Dp and Cat-Back?

Have a custom execution exhaust shop found a unblemished 3" exhaust system (Turbo-to-Tip). It should cost well less that 0. And then you can use the muffler and exhaust tip of your choice.

Which Fuel Cut Eliminator is recommended?

The Greddy Bcc (Boost Cut Controller) is highly recommended.

What does the Fuel Cut Eliminator do?

The factory Ecu is programmed to start a fuel cut if the manifold pressure exceeds 14-15psi. It does this as a safety portion to forestall what the Ecu sees as over boosting. The Fuel Cut Eliminator effectively eliminates, or at least raises the cut to a higher pressure. A reprogrammed Ecu can also eliminate this function.

Which boost gauge is recommended?

Any high potential boost gauge will work well. Accuracy is the leading feature to look for. Autometer gauges are a good value. The Japanese gauges, A'Pexi, Greddy, Hks, etc., have more features, but at a much higher price.

Where can the boost gauge be installed in the interior?

If you want to mount it in the dash, the two most favorite places are the Clock location (which holds a 52mm gauge), and the Air Vent beside it (which holds a 60mm gauge). You can also use an A-Pillar gauge pod.

What is the stock boost pressure?

11-12psi

Are Cam Gears a good modification for the Supra Tt?

Yes, they have been shown to provide a 5-15rwhp gain on a Bpu(Tm)'d car. But to excerpt their potential, you must have them tuned, by a knowledgeable tuner, on a dyno. And most of the power gains will be seen on the exhaust side. I also recommend buying cam gears which feature 5-bolts.

Are Under Drive Pulley(s) a good modification for the Supra Tt?

Most of the crank-shaft under-drive pulleys need the discharge of the factory torsional damper.

This is from Mkiv.com :"this is Not an external (harmonic) balancer, as the crankshaft is fully balanced, rather it dampens both the axial twisting couples produced by the firing pulses, and the radial bending occasion from the accessory drive belt."

Basically this device provides crutial isolation between the machine driven accessories, and the crankshaft. However, discharge of this can provide a 10-15rwhp gain, but at a cost for long term use.

Do I need to upgrade the ignition when upgrading to Bpu(Tm)?

The stock ignition system is Very capable of supplying enough fire for a Bpu(Tm)'d car. The stock ignition system uses 6 large coils, one for each cylinder. So the system is capable of supporting Very impressive Hp levels. You may need to convert to a colder range plug with a tighter gap (see below).

What about the spark plugs, which are recommended at Bpu(Tm) or higher level?

Basically you want similar plugs as stock, but a cooler heat range and a smaller gap. The stock plugs are Ngk Bkr6Ep-11 (2978) and are platinum tipped and have a .044 (1.1mm) gap. The ideal Ngk exchange for a modified Supra would be the Bkr7E (6097). It is one range cooler (the '7'), is non-platinum tipped (the lack of the 'p') and has a smaller .0315 gap (lack of the '-11'). This plug is also called the Ngk 6097 and they are fairly inexpensive. Platinum tipped plugs are not desired for high power applications, Iridium plugs are more prefered. Unfortunately their doesn't seem to be a Bkr8E which might be great for high-Hp Supras.

Another good plug to try is the Denso Iridium Ik22 or Ik24. These plugs may last longer than the above mentioned Ngks, but are also 6 times as expensive. The stock exchange plug would be the Ik20, the Ik22 is one step cooler, and the Ik24 is two steps cooler than stock. The Ik22 would be good for ~400rwhp to ~600rwhp. The Ik24 would probably be a good selection above that. Two other plugs generally used are the Ngk 3330 (Bcpr7Es) which differ much more from the specifications of the stock plugs than Ngk 6097. Also the Rapid Fire #5 used to be very popular, but are more expensive, don't last as long, and have fallin out of favor. Both of those plugs have been known to cause wee stumbling at idle. Plugs on Supras do not live long, usually around 5,000-10,000 miles. So I recommend replacing them with every other oil change.

What is the Hks Vpc and Gcc?

It is an electronic device, which electronically and physically removes the highly restrictive mass airflow sensor from the intake tract. Vpc stands for Vein Pressure Converter. The Hks Gcc is a device that allows additional fine-tuning of the Vpc.

Do I need an after-market Blow off Valve?

It is not de facto required, but it is a good idea. The factory by-pass valve is prone to failure, and an aftermarket Bov is probably a wise investment for preventing turbo damaging compressor surge. And it sounds cool too. However, it must be noted that if you still have the factory mass-air flow sensor, a blow-off valve, which is vented to the atmosphere, may cause stumbling between shifts.

Can I run Nitrous Oxide on the Supra Tt, even if I am already at Bpu(Tm) power levels?

Yes. Most habitancy run 50-75 shot wet multiple systems. If you want to run a higher shot than this, you might want to think a well-designed direct port system. I have seen as much as a 200-shot used on one of these systems, and an upgraded fuel system would be a must.

450hp just isn't enough, what can I do?

Ah the possibilities Basically you are only wee by your imagination, and your wallet. You know what they say, speed costs money, how fast do you want to go?

The real power lies in singular and Twin turbo upgrades, and the options are limitless. You can either build a mild motor that puts out 450 Rwhp all day long with instant boost response, or a 1000+ Rwhp monster.

Unfortunately, things start getting more difficult after uncomplicated Bpu(Tm) modifications. Modification becomes more than "bolt on Downpipe, gain 50hp". Things like tuning, parts selection, and matching combinations of parts come to be much more important. However, this is the case with Any high Hp car. Actually, even at exceptionally high power levels, the Supra Tt is still easier to excerpt power from than almost any other execution car. But it should be kept in mind, that it wouldn't be as uncomplicated as the Bpu(Tm) bolt-ons.

If you just want something that will toast that pesky Viper Gts. Then focus on a mild singular turbo upgrade (T04S04, T60-1, Sp57-Sp61). Along with this, you should setup a front mount intercooler, a fuel controller, fuel pulsation damper bypass and Egt gauge. This is assuming you have done all the Bpu(Tm) mods, plus Bov, Ebc, Cam Gears. With tuning, and a few odds and ends, you should be able to pull 450-500 Rwhp (490-580 crank Hp) numbers while on a stock fuel system (assuming it is in great condition). This would be a total investment of almost ,700-,500 in engine/electronic components (also includes the proper gauges). If you already have the Bpu(Tm) mods or Fmic, etc., you will spend less than this. The divergence in prices reflects the cost of higher end parts and increasing of a Hks Vpc to replace the restrictive stock Maf.

The next level would need a completely upgraded fuel system, and execution cams would be recommended, as well as additional electronics (programmable machine management such as the Aem, or Vpc/Gcc/Ecu combo, etc.). This would allow you to run much larger turbos and injectors. You can make it past the 700Rwhp range without needing to replace the internals of the motor with stronger components, even at these power levels, if properly tuned and maintained you should support a fair estimate of reliability while still on the stock internals, as some habitancy have eclipsed the 800Rwhp level while still running stock bottom ends in their Supras. If you choose to go ahead and build up the bottom end, then the skies are the limit as far as power goes. Just make sure to have part selection, installation, and tuning done by competent and experienced persons. Although this should hold true at Any level of modification.

Should I setup a Turbo Timer?

Absolutely. Unless you don't mind sitting in your car while it idles down every singular time you need to turn the car off. A Turbo timer keeps the machine running for a preset time once you turn off the ignition. So you can take off your keys, and lock up the car and not have to worry about it, it will shut off on it's own. This is leading for the life of the turbos. If the turbos are not given time to cool down, it can overheat the oil and cause coking which will block oil flow to the turbos and damage bearings and cook seals.

How much is the Supra's power output affected by changes in ambient temperatures?

Very noticeably, just as with most turbo cars, the Supra Twin Turbo can be very temperature sensitive. Especially with the stock turbos and intercooler. On a Bpu(Tm) car, I would not be surprised to see a 10 percent allowance between 50-60deg temperatures, and 90deg plus temperatures

Will the stock clutch hold the power levels of a Bpu(Tm) car?

It depends on the health and wear on the stock clutch. If it is in good condition, yes, it will hold the power, pretty well in fact, although you may touch clutch slip while at full boost in high gears such as 5th and 6th. If you drive vigorously, meaning you run at high boost frequently, then the life of the stocker will be Greatly shortened. Be surprised if you see an extra 10,000 miles after Bpu(Tm).

Can I resurface my flywheel when replacing the clutch?

It is not recommended. Buy a new Toyota Flywheel.

Can I setup a lightweight flywheel?

Yes, but be aware that they can create a lot of noise at idle, and can forward more vibrations and shock to the high-priced Getrag transmission.

Why is pulling the Trac fuse beneficial over just turning it off with the switch on the town console?

Just pushing the "Trac Off" button only partially disables the Trac system. It disables the Trac throttle body and Trac funtion straight through the Abs system (on 93.5-96 only), but not the Trac system's ignition timing retard function. Unplugging the Trac fuse eliminates both functions, as well as the 155mph speed limiter, which works straight through the trac system. The fuse can be found in the main fuse box on the driver's side of the machine compartment. It must be noted that removing the fuse will cause the Trac light to stay on, but you'll get used to it.

Will the Trac system improve the cars performance?

No. The Trac system was calibrated to improve traction in slippery conditions. It was not calibrated with execution in mind. When the Trac system senses a loss of traction, it comes on hard, cutting power drastically; this will do nothing but hurt performance. I also would not rely on the Trac system for providing stability at high speeds, if you were to loose control, it would be too slow and clumsy, and would more than likely hamper your efforts to gain control.

How can I take off the factory 155mph speed limiter?

Remove the fuse for the Trac system. The speed limiter works straight through the Trac throttle body.

What is the Supra Tt's top speed with the Trac fuse removed?

There is some turn over on this subject. There are rumors that 180 can be achieved. But by going with the numbers, 168-172mph in stock form seems possible.

What is the Supra Tt's maximum theoretical top speed? Can it exceed 200mph with enough power?

Lets find out.

The Supra Tt with the 6-speed has a stock machine redline of 6800rpm, and a 6th gear ratio of .79:1, with a rear axle ratio of 3.13:1. Now we multiply our 6th gear ratio times our rear axle ratio, and we find out our final gear ratio is 2.472:1. Now we divide 6800rpm by our total gear allowance of 2.472:1 and we find out our rear axles, and therefore wheels are spinning at 2751rpm at 6800 machine rpms.

Now we need to infer our tire circumference. The rear tires section width it 255mm, and the sidewall's aspect ratio is .40, so our sidewalls are 102mm. Now, to convert this to inches, we divide this by 25.4, which equal's 4.015 inches. Now multiply this by two, since we have two sidewalls making up the total diameter, and add the wheel diameter of 17", and we see a total diameter of 25.031 inches. Now to find out our circumference, we multiply that estimate times pi (3.14), and we find out the circumference is 78.59 inches, now divide that by 12 to convert to feet. And we get 6.549 feet total circumference.

Now multiply our tire's revolving speed, by the tire's exterior circumference, and we find that the tire is exterior 18,016 feet per minute, divide that by the 5280 feet in a mile, and we find we are exterior 3.412 miles per minute, now multiply that by the 60 minutes in an hour, and we find we are traveling 204.7miles per hour @ 6800rpm in 6th gear. If the engines redline is increased to 7500rpm, which it often is, because of a higher flowing turbo. Then our maximum speed would be 225.8mph, given enough power of course.
