Stall torque converter

Basically stall means when the torque converter locks-up under a load. With that, if you take a car with a 500RPM stall converter and you hold your foot on the brake har and hit the gas at the same time, (as if you were going to power brake), the general RPM in which the tires will break loose is at about 500RPM. The more torque an engine makes, the higher the rpm the converter will stall , or lock up at, and transfer that torque to the transmission. There are two types of stall speed-foot brake stall and flash stall. Stall speed and stall speed selection are terms that are frequently misused and misunderstood when shopping for a torque converter.

Most of the time they are confused with other elements of a torque converter or not measured properly. This device is found in every automatic transmission, acting as the lungs of this machine. Stall speed is the amount of rpm the engine can reach with the brakes locked and transmission in gear before the drive wheels turn. The stall speed assigned is simply a way to rate the converter’s performance level. The Basics Of Stall Speeds.

A torque converter’s job is to take the horsepower an engine produces and multiply that to make the car accelerate. The torque converter is a hydraulic coupling which takes the engine’s mechanical force and converts it into hydraulic pressure. Get proven performance and reliability from BM, TCI, Turbo Action, Hughes Performance, ATI Performance Products, Performance Automatic, and other leading brands. Choose from a variety of stall speeds to help you put maximum low-end power to the pavement. Don’t stall—launch your performance to the next level with top-quality torque converters!

Effective in-vehicle torque converter stall speed is defined as the rpm the engine can reach with the brakes locked and the transmission in gear before the drive wheels turn. I just wanted to let you know how thrilled I am with the Stallion converter. It is a refreshing change to buy a product that completely lives up to its billing. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. Buying High Stall Torque Converters.

To choose the right torque converter for your vehicle the stock parts and any alterations and additions should be considered. This will help pair up the power, transmission, and all variables with the right torque converter that has the proper stall speed for your set up. Interpreting the stall -speed test result If the RPM reading is lower than the specifications for your particular torque converter and engine, it means the torque converter is failing and needs to be repaired or replaced.

The industrial Torrington-type incased bearings give JEGS Torque Converters the ability to handle thousands of pounds of torque throughout the converter while the customized turbine hubs and impeller fins maintain high quality, strength, and durability. Three scans ensures 1 accuracy of your order. Each salesman has his own direct tol. What is torque converter stall speed? It is, however, a very important component of automatic transmissions.

Stages of operation: stall. There are some trends, which appear in the torque converter selection process, that tend to influence the selection of stall speed.

For example, a three-speed prefers a converter designed to work. STALL SPEED Torque converter stall is a commonly used term and is commonly misunderstood. Stall is the speed at which the converter will hold the engine speed and not allow further gain (i.e., the engine stalls). The key word here is engine.

The speed at which stall occurs with a given converter is a function of engine peak torque. You can roughly check your converter ’s stall speed by putting the car in Drive, pressing firmly on the. This flow produces a maximum torque increase of 2:when the turbine is stalled. When enough torque is developed by the engine and the converter , the turbine begins to rotate and turns the transmission input shaft. RPM Stall Torque Converter.

Most torque converters multiply torque in a 2. Within the stator is the one-way clutch splined onto the transmission’s stator support shaft. And while stall speed is important for a good. Phoenix Transmission Parts.

FREE Shipping on eligible orders. We know our parts and products. Theoretically, for maximum acceleration, the stall speed of the torque converter should match the peak torque rpm of the engine.

If a high performance engine makes power at a higher rpm, then a higher stall speed torque converter can put more power to the ground quicker. A 5RPM converter can be installed without seeing a 5RPM stall if there is not enough torque provided by the engine. Meanwhile, if you install the 5RPM converter in a vehicle with a big block engine with massive torque , you may get more like 0RPM stall. Stall speed is determined by several factors, including the distance between the impeller and the turbine and the design of the stator.

Stall speed is the maximum rpm that an engine can obtain against the hydraulic load of the torque converter with the transmission shaft held stationary. The best performance is obtained with a converter that has a stall speed slightly higher than the rpm of the engine when it starts to produce its strongest usable power. You can diagnose any torque converter problems by doing a stall speed test but before that, you should clearly know the stall speed specifications of your engine and the torque converter first. Precision of New Hampton is the largest privately -held torque converter remanufacturer in the world. We make torque converters for all makes and models: on highway, off highway, as well as OE converters in small runs up to 20a year.

That would give you your converter stall speed with your engine, at a specific vacuum. Perhaps interesting for tuning, but quite irrelevant to use as a characteristic of any converter , or to compare converters. When the best will only do, look no further as there is not a better torque converter on the market than a Revmax.

Billet Stall Torque Converter on the market. This means that a torque converter designed to stall at 5RPM with a mild small block might stall might stall at 0RPM behind a fire-breathing LSX454R with 7pound feet of torque. Power Adders or Naturally Aspirated.

Learn about the torque converter and see pictures of a torque converter. Once again, the more torque your engine makes, the higher your torque converter will stall. Find Torque Converters with 700RTransmission Type and 0rpm Advertised Flash Stall Rating (rpm) and get Free Shipping on Orders Over $at Summit Racing!

This “New Generation” torque converter is available for General Motors, Ford and Chrysler transmissions. The “XTM” is slightly higher stall for gas engine application and the “XFM” is a lower stall for diesel engine applications. A quality torque converter , whether it be for towing, muscle car restoration, high performance, or an all out race converter , requires more than just a high stall speed.

A high stall converter can improve performance, but of equal importance are efficiency, torque multiplication and durability.
