Boyesen SuperCooler Water Pump Cover and Impeller Kits are specifically designed to enhance the performance of your engine’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. The Boyesen Supercooler can reduce engine temperatures by as much as 13 degrees, as confirmed by tests on the KTM 250F. How does the Supercooler achieve this? Hydrodynamics. Boyesen’s investment-cast aluminium water pump cover has bigger water inlets, a sculpted design, no casting seams, less restrictive corners, a more efficient impeller and less cavitation.
Did you know? The first Boyesen Supercooler was developed for the Factory Yamaha 2 Stroke of Damon Bradshaw and were not available to the public at that time? The first 4 Stroke application was for the 2006 KX450F of James Stewart as the team were constantly struggling with overheating issues!
