Torque converter stall calculator

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. Click on the headings below to expand the specific calculators needed.

The torque converter is designed so the fluid flows from the impeller to the turbine then back to the impeller through the. The stall speed assigned is simply a way to rate the converter ’s performance level. For example, a three-speed prefers a converter designed to work.

Several conversions relating to torque. Check out our Conversion Software for Windows. Each converter builder will have to calculate things based on the way they do the internals of the converter because there is more than one way to skin a cat.

The range level will tell you a lot about what to expect from the torque converter. Stall speeds are a great way to rate torque converters performance level. Careful selection of the right components should result in a torque converter that can maximize your race car’s performance. The elements that affect torque converter stall are: Diameter of the torque converter. The Mountz torque calculator allows you to convert torque measurement from one type of unit measurement to another.

We measure torque by multiplying two factors—amount of force applied and distance from the point of application. A torque converter is a tunable device. This converter is approximately 6to 0RPM lower than stock. That’s why it pays to run a Spicer torque converter.

You can practice using this calculator with these examples: 1) What is the horsepower when an engine is producing 4foot pounds of torque at 0rpm? Click on Horsepower, enter the torque and rpm, click on Calculate and the answer is 361. An engine producing 3horsepower at 0rpm is producing how much torque ? Adding stall speed to the torque converter increases the power available to accelerate the car more quickly. Unfortunately, additional stall speed also increases the slippage in the converter.

Hard-working engines—like those used for mining, forestry, construction or material handling—need torque converters designed to match their high stall speed transmissions. Power Adders or Naturally Aspirated. Once again, the more torque your engine makes, the higher your torque converter will stall. 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. An engine generating 3horsepower and 4foot pounds of torque is rotating at what rate?

Click on RPM, enter horsepower and torque , click Calculate and the answer is 464. The APP can be used for all three international measuring systems – American (Imperial), Metric and International Standard (S.I.). Horsepower is the measure of power that produces the mechanical output.

Failing torque converter symptoms include temperature gauge overheating, large amount of black material in flui stall speed increase, or strange sounds coming from the torque converter. This are all situations where replacing the torque converter is a good idea. When you choose torque , this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 2(conversion between foot-pounds and horsepower), divided by the RPM of the engine. However, a converter must also be matched to the characteristics of the driven machine and other factors such as stall torque ratio, engine lug, braking and cooling.

Ever wonder what exactly a torque converter is? This video shows what they are and how they work with transmissions. 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. So without a clutch, when slowing down to a stop, an engine would stall as the load from the transmission would drag it below its workable rev limit.

Everything you want and need to know about choosing the correct torque converter but were afraid to ask! Also, explore many other unit converters or learn more about torque unit conversions. In a vehicle with an automatic transmission, the torque converter connects the power source to the load. You have a torque converter instead.

How to choose the stall speed of a converter ? You can find all sort of descriptions and explanations, but your first interest is in what your stall does for your car. 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. That is why a dynamometer sheet is the best tool you can have when choosing a torque converter. The significance of the torque converter is that it allows the output shaft to be stopped with out stalling the engine, and without physically disconnecting the input and output shafts.

Converter guys will give you a converter that is too loose. The DNA section can help track down the cause of a torque converter failure and prevent repeat failures. What color are Transtar torque converters ? This torque converter is designed for the muscle car and street rod crowd with enough stall to launch the car and efficient enough to drive everyday. It has many of the same design features of our Bullet Race Series torque converters with the ability to drive them on the street. Choosing the right torque converter for your vehicle can seem like a daunting task for most people.

I am looking at aftermarket converters and would like some input on stall speed. There are a lot of different torque converters and stall. Re: stall torque converter recommendation The reason for stall converters is to get the engine up to its power band as quick as possible.

Actual stall speed will vary depending on the load that the torque converter is subjected to.

We can take a look at your existing converter or can build you a whole new custom build specifically for your combination. Torque Calculators : Enter value, select unit and click on calculate. Need some help with torque converter stall speeds. I have a 4with a comp cam has 2duration on intake and exhaust and.

I have 3gears but willing to change if needed. 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. Increasing the performance of your vehicle takes a lot of time and money and it can all be wasted if you don’t get a torque converter specifically designed to match to your vehicle and maximise all that extra power and speed.

Slingshot are specialists with over years’ experience custom building and modifying high stall torque converters.
