High Stall Torque Converter

Torque Converter

High Stall torque converter – A torque converter (TC), like the clutch in a manual, transmits power from your engine to the auto transmission. That’s where the similarities end as the TC is a fluid coupling as opposed to a material lining clamped onto a steel flywheel. All traditional automatics have a TC, and they allow the engine to idle without power transfer to the gearbox, then as the engine RPM increases slightly the fluid coupling starts to… um, couple and power is moved to the rest of the driveline and the car moves. A high stall TC is a redesign of the coupling to allow the engine to rev higher before power is transmitted… why? Glad you asked - two reasons, 1/ a larger camshaft typically needs to idle higher, like maybe 950rpm or 1000rpm, with a standard TC at 950 or 1000rpm the engine will try and push the car which can be unpleasant. 2/ a high stall TC can (and should) be matched to the engines power-band, this enables the engine to get into the power band before too much power is transmitted and is primarily designed to aid acceleration (drag racing). It goes much deeper than this but this will do for a basic description. We use Dominator for our High stall TC requirements and they are based in Thomastown, Victoria.
