The electric water pump drive kit was designed to alleviate the power drag produced by conventional pulley drive units.
A heavy duty electric motor, turning at approximately 1,500 rpm, is more than adequate to fulfill cooling needs w/o draining horsepower from the engine.
The unit can be turned on/off manually, even with the engine off.
The kit is complete with motor, mounting brackets, extra long bolts, spline pulleys, drive belts, wiring and switch.
