PRW has introduced evolutionary water pump design improvements that maintain the performance edge over the competition. Performance Quotient by PRW engineered pumps flow 35 gallons per minute at 4,000 RPM, with minimal cavitation and proportionally increased flow rates at 5,000 RPM and above.

Equalized water flow distribution and pressure-balanced water passages minimize internal engine hot-spots making these pumps an excellent alternative for not only racers, but also marine, trucks, towing, and motorhome applications.  Cruisers and hot rodders will appreciate the improved cooling at low speeds
