Performance quotient engineered pumps will flow 35 gallons per minute at 4,000 RPM, with minimal cavitations 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. Cruisers and hot rudders will appreciate the improved cooling at low speeds and the polished aluminum water pump bodies. Block-to-hub 5.8125.
