When in doubt, e-mail or call us.

Stall Speed: The stall speed of a converter is usually determined in a particular vehicle. Place the vehicle in a forward gear, apply the brakes, and depress the throttle until the engine can no longer increase RPM.
CAUTION - The test should last only 5 to 10 seconds! Overheating can occur very fast!
If the wheels spin, the test is invalid.
The RPM developed by the engine is considered to be approximately 80% of the actual stall of the torque converter, in this application. The difference in a small block, big blocks, cams, fuel system, weight of vehicle will all effect the actual stall speed.


1) Converter stall speed above 2800 RPM is not recommended for street use. Excessive RPM for take-off and overheating will occur in normal driving conditions.

2) For acceptable performance, axle ratios should be 3:42 to 1 or greater. Ratios in the high 2's and low 3's do not perform as desired with converters with stall speeds of 2000 RPM or greater.

3) Stall converters of 3000 RPM or greater are not recommended for use with engines with "advertised" cam duration of less than 292.

4) Vehicles equipped with transmission brakes, nitrous, blowers, and turbo-chargers require converters equipped with special features. Call or e-mail us.
