Boyesen SuperCooler™ Water Pump Cover and Impeller Kits are specifically designed to enhance the performance of your machine’s cooling system. These high-flow, hydrodynamic water pump kits have been tested and designed to flow more coolant. By increasing the flow, the engine will run cooler at a more constant temperature.

HYDRODYNAMIC EFFICIENCY

The Boyesen Supercooler will reduce engine temperatures by as much as ten degrees, as confirmed by Boyesen’s coolant-flow Dyno testing. How does the Supercooler achieve this? Hydrodynamics. Boyesen's investment-cast aluminum water pump cover has bigger water inlets, a sculpted design, no casting seams, less restrictive corners, a more efficient impeller and less coolant cavitation.
