Torque Converter Selection - Summit Racing Quick Flicks
What does a torque converter do? A torque converter is a fluid coupling
device that transfers power from engine to transmission and multiply the
torque being created by the engine.
There are three major components that make up a torque converter.
The Fluid Impeller is the only part of the torque converter that is
physically attached to the engine. The impeller creates fluid motion within
the converter to create a transfer of power. The Stator redirects fluid
flow towards the impeller. The Turbine Assembly transfers the motion
between the engine and the transmission. Another important aspect to
understand is Stall Speed = RPM when the engine sends all available power
to the transmission.
Torque converters have 2 different types of stalls that they can produce.
The 1st type is Foot Brake Stall. Foot break Stall is an inaccurate way to
measure torque converter stall.
Flash stall is the actual stall of the torque converter. Flash stall is
always listed in range which is determined by different attributes such
vehicle weight, gear ratio and tire size. The flash stall rating is the
only true and most accurate stall rating that you will find on a torque
A few rules of thumb to take from this video are: First select a converter
that stalls at 500 RPM higher than the camshaft. Converters installed in a
big block engine usually stall 300 RPM higher than a small block. Choose a
converter that will stall below the highway cruise RPM. For additional
