Torque Converters

Performance torque converters are generally grouped by size (diameter) and stall speed.

As the diameter of a torque converter
decreases, the stall speed (RPM) goes up. Most of the factory torque converters are 12-13 inch diameter and have a stall speed around 16-
1800 RPM. This promotes excellent fuel economy and drive ability because
they are specifically designed for these purposes.

The problems arise when the modifications are done to the fuel system, camshaft or other engine control systems. Smaller diameter torque converters are needed to provide more slip at idle. This allows engines with a lot of camshaft to idle better. As the torque converter and
horsepower range is moved higher through the RPM range, the smaller torque converters with their higher stall speeds provide maximum torque multiplication where needed. Also the same torque converter will react differently when used behind different engines.

So make your torque converter selection with the help of qualified personnel.

Performance Automatic has endless converter combinations to make your car or truck perform at its utmost potential.
