Abstract

An electric motor is connected via cog belt to a dual purpose pulley on the water pump of an automobile, to increase power available from the engine so that during racing maximum horsepower can be achieved. Enhanced cooling of the engine is also obtained.

Claims

1. An engine performance apparatus, comprising:

a water pump;

a bracket secured at a proximal end to said water pump and extending therefrom;

an electric motor secured to a distal end of said bracket; and

a dual purpose, one-piece pulley operatively secured to a drive shaft of said water pump, said pulley having a first drive adapted to engage a belt and a second drive with a cog surface adapted to engage a cog belt, such that in a racing mode the second drive is engaged by the electric motor via the cog belt and in a conventional use mode the first drive is engaged by said belt operatively connected to said engine.
