Boyesen

Super Cooler

Heat is the #1 Enemy of 4-Stroke Engine Performance

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 ten degrees, as confirmed by tests at Team Kawasaki. 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.

Internal engine heat, although needed for horsepower, is also extremely destructive to your engine if it is not managed properly. Internal engine heat, although needed for horsepower, is also extremely destructive to your engine if it is not managed properly. Internal-combustion engines burn fuel hotter than the melting temperature of engine materials. When an engine is operating out-of-balance with its cooling system’s capacity, the internal temperatures often rise to levels that cause damage to the cylinder, piston, and valve-train components. If these parts become heated over the optimal operating upper limit range, component damage will begin to occur. Reduced to its common reasons for being essential in an internal combustion engine, cooling system efficiency can have a dramatic influence on the longevity of the internal working components of your bike’s engine. These include the reduction of thermal stresses and strains caused by pre-ignition and detonation (particularly the latter), distorted cylinder bores, potential damage to pistons and rings, and damaged valve-train components. yamaha Models Years Cover YZ 85 2002 - 21 .BK YZ 125 1998 - 04 .BK YZ 125 2005 - 26 .BK YZ 125X 2020 - 26 .BK YZ 250 1999 - 26 .BK YZ 250X 2016 - 26 .BK YZ 250F 2001 - 13 .BK YZ 250F 2014 - 18 .BK YZ 250F 2019 - 26 YZ 250FX 2015 - 19 .BK YZ 250FX 2020 - 25 WR 250F 2001 - 13 .BK WR 250F 2015 - 19 .BK WR 250F 2020 - 26 YZ/WR 426F 2000 - 02 .BK WR 450F 2003 - 15 .BK WR 450F 2016 - 21 .BK YZ 450F 2003 - 09 .BK YZ 450F 2010 - 13 .BK YZ 450F 2014 - 22 .BK YZ 450FX 2016 - 22 .BK 05-0788 05-058 05-077 05-077 05-053 05-053 05-050 05-076 05-0796 05-076 05-0796 05-050 05-076 05-0796 05-072 05-072 05-075 05-072 05-071 05-075 05-075
