Boyesen Waterpump Blue - Yamaha YZ250 YZ250X
The Boyesen SuperCooler water pump kit is an aluminium investment cast water pump cover and impeller combo; specifically designed to enhance the performance of your engines cooling system. This high flow, hydrodynamic water pump kit has 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.
Why is cooling your engine very important?
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.
How does the Boyesen Supercooler work?
SUPERIOR COOLANT FLOW DELIVERY
Stock waterpump interiors often exhibit square-edged internal channel surfaces and sharp-edged fluid inlet passages. These imperfections are most often the result of mass production tooling limitations and are the leading cause of most stock waterpump's inability to deliver enough coolant to your engine when it is raced hard, or for long periods of time in hot and muddy conditions. This is where the Supercooler shines in comparison to your stock waterpump system. The Supercooler's Opti-Form interior surfacing process eliminates all coolant flow 'pinch-points' resulting in a hydrodynamically efficient interior that dramatically increases coolant flow efficiency and ultimately leads to increased fluid flow re-entry rates into your bike's engine.
BIG INLETS FOR INCREASED FLOW AND CAPACITY.
Stock waterpump systems typically have relatively small intake passages which ultimately reduce their overall coolant re-entry efficiency capacity and greatly reduces internal cooling system fluid pressure. Internal fluid pressure is the most important element that affects how effective your cooling systems is at engine heat dissipation. By using larger inlet openings the Supercooler allows your bike's coolant to re-enter into your engine faster and get to your expensive cylinder faster, ultimately making more coolant available to absorb and remove heat. Less heat = more horsepower at the end of the moto.
PROFLOW
The Supercooler's hydrodynamically optimized impeller increases overall coolant flow rates and virtually eliminates coolant cavitation when compared to stock waterpump designs. The Supercooler's impeller is designed to be HYDRODYNAMICALLY EFFICIENT, meaning that it not only propels the cooling fluid into the engine without cavitation, but it demands less parasitic loss from the engine. These two factors allow your bike's engine to produce more horsepower and most importantly MAINTAIN that output throughout the long summer motos, or in muddy conditions. Boyesen's patented Pro-Flow anti-cavitation impeller is one of the most beneficial performance improvements when comparing the Supercooler to stock waterpump systems. The anti-cavitation performance of the Pro-Flow impeller increases overall coolant flow rates and increases your bike's ability to handle high heat dissipation.
