| 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 aluminum water pump cover has bigger water inlets, a sculpted design, no casting seams, less restrictive corners, a more efficient impeller and less cavitation. Most MXA test riders feel that both the Suzuki RM-Z and Kawasaki KX-F offer marginal cooling efficiency. FEATURES: CASTING By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit. Boyesen’s design takes advantage of everything from Bernoulli’s Effect to biological studies. SUPERIOR INTERNAL HYDRODYNAMIC SHAPING Stock water pumps aren’t very hydrodynamic. Their internal shape and impeller create excessive amounts of air bubbles in the water. Air bubbles lessen not only water flow, but the amount of water per cubic gallon. Boyesen’s Nautilus-shaped cover and impeller increase pump capacity. OPTIMIZED WATER INLET DIAMETER (High Cooling Capactiy) Unlike the stocker, Boyesen’s water inlet has an increasing diameter and artfully curved shape. This is a vast improvement over most stock inlets, which decrease in diameter as they near the impeller and have a 90-degree bend at the pump (a very serious hydrodynamic no-no). OPTIMIZED IMPELLER (Patented nautilus style impeller) Boyesen’s patented impeller design is 25 percent more efficient at moving water than the inefficient stocker. * WIN THE WAR ON HEAT, BOLT ON A SUPERCOOLER NOW* "My YZ450F over heated sometimes in the nasty stuff. I installed the SuperCooler kit and have not had a problem since. It works great and is not just bling for your bike, worth the money if running hot is an issue." - Jordan See dirtrider.com test here |
