PRW has continued the evolutionary process on your existing line of water pumps. Performance Quotient Engineered pumps will 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 trucks, towing, and motorhome applications.

Designed for serious competition, racers and engine builders can look forward to;
