# What is considered a low stall torque converter?

## What is considered a low stall torque converter?

It’s under those same circumstances that the stall speed becomes important. With a low stall speed. But both the Ford and Dodge torque converters stall between 2,000 and 2,500 RPM – so with a heavy load, the torque converter won’t start turning the rear wheels until well beyond the engine’s torque peak.

When does a torque converter stall the engine?

Stall speed is the speed at which the converter holds back or limits the engine speed if the transmission output is prohibited. When your torque converter prevents the power transfer from your engine to your transmission, it increases the engine’s RPM stalls. For example, when you press down on your gas pedal,…

What should I consider when buying a torque converter?

Sure, stall speed is very important, but it is not the only factor to consider when buying a torque converter. You should also consider torque multiplication at launch and high-end efficiency. Selection of these components will not only affect your stall speed, it will also affect your converter’s efficiency.

### Can a high stall converter destroy a transmission?

Plus, the higher the stall speed, the more heat the converter will make with hydraulic fluid inside of the converter. Normally a high stall converter will be able to make enough heat to destroy a transmission if you are holding the line too long at full RPM if the stall speed is higher than 3500RPM.

What happens when you over estimate your stall speed?

If you over estimate, your stall speed will be lower than intended, which will reduce your torque converter’s performance. If you are unsure about these modifications, the experts at RevMax Performance Torque Converters can help.

How do you calculate stall speed?

The formula is to calculate stall speed is: V = √( 2 W g / ρ S Clmax ) V = Stall speed m/s ρ = air density KG/m^3 S = wing area m^2 Clmax = Coefficient of lift at stall W = weight KG The formula accounts for altitude by input of the appropriate air density figure.

## What does stall mean on torque converter?

A torque converter has three stages of operation: stall, acceleration, and coupling. Stall is when the transmission is in gear , but the brakes prevent the car from moving. At stall, the torque converter can produce maximum torque multiplication, called stall ratio, if sufficient input power is applied.

What is stall speed converter?

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. Converter stall speed must be high enough to put the engine into the torque range where it can most efficiently launch the car.
