The OptiFlo™ CR500 "phi" HV Impeller, another must-have item for your Honda CR500 Engine!
The “phi” impeller vanes are computer-designed using “
Golden Ratio” proportions based on the CR500’s H2O pump housing.
This, as well as very close tolerances between impeller and housing, offers 1.5 average GPM
more coolant flow along the entire RPM curve. The increased flow reduces the cycle time between the engine and the radiators, providing more adequate heat removal.
The overall benefit is lowering the engine temperature by up to 20°F over the competition’s impellers.
Also, the high efficiency of the "phi" Impeller
frees horsepower that your engine is already making. Dyno testing showed
up to 2.12 HP freed over a 1750 RPM range compared to the competition!
Remember, horsepower/RPM = heat. Preventing your engine from heat soak is the KEY to building and maintaining maximum engine performance. The more efficient the engine’s cooling system, the more heat (horsepower) it can handle.
Whether you’re racing Outlaw Karts, GNCC, Hill Climb, Sand Drags, Super Moto, or MX--railing tight single track, sand dunes, or just love the latest enhancement for your CR500.
Trust MSV Racing’s “phi” Impeller to help put you at the head of the pack! (Look at the pics and check out the data. No other CR500 parts company will show you the proof that they are the best.
It’s the MSV Racing way!)
(Mino, Frank’s MX and AS3 are the SAME oversized impeller with a spacer)
NOTE: To ensure ease of installation, each impeller comes with an H2O pump cover gasket set (2 gaskets) for a seamless install.
"Fantastic fit and finish. Easy install. This guy does great work to improve the sore spots on our beloved big bores."- Billy Brown
