Definitions:

Vortex Flow

Eddy force created by rotational movement. Both a whirlpool and a tornado produce vortex flow, as do the dynamics of a torque converter. See vortex oil flow.

Torque Multiplied

The increase in torque generated through the use of a mechanical system like a gearbox, allowing for greater force to be applied without increasing input power.

Flex Plate

A component in automatic transmission vehicles that connects the engine to the torque converter, allowing for flexion and torque transfer.

Crankshaft

A crucial engine component that converts the reciprocating motion of the pistons into rotational motion to drive the vehicle.
