How To Choose The Right Torque Converter Stall Speed Brand And Size Guide

Stall speed also depends on your engine. If you reuse a torque converter with a different engine, the stall speed will also be different.

For instance, a torque converter with plenty of clearance between its inner components will have a higher stall speed than a converter without much clearance.

For instance, if your camshaft operates between 1,600 and 5,200 RPM, a good torque converter stall speed would be 2,100 RPM.

If your cam duration goes up to 268 degrees, a 2,400-3,000-stall converter is better.

Drop by a nearby truck stop or weighing station to see how heavy your car is. According to the U. S. Department of Energy, “light-duty” vehicles are less than 10,000 lb (4,500 kg), while “medium-duty” vehicles are between 10,001 and 26,000 lb (4,536 and 11,793 kg).

If you have a heavier car, you’d need a torque converter that can handle the increased RPM.

Yutaka Giken and ZF Friedrichshafen are also well-respected manufacturers.
