The OptiFlosm CR500 “phi” HV Impeller, another must have item for your Honda CR500 Engine!
There are only 3 ways to add extra cooling to your CR500:
- Bigger frontal radiator area. Not going to happen in the confines of the CR500 radiator shrouds and thicker radiators only slightly delay the inevitable
- Cooler air going through the radiator. Strictly subject to the air temperature your riding in.
- More Coolant Flow. This is where MSV Racing’s “phi” High Volume Impeller works its magic!
Rigorous flow bench testing, real-world MX race testing, and top Outlaw Kart racers validate that the MSV Racing’s “phi” impeller dramatically improves your CR500’s H2O cooling and pumping performance over OEM, Frank’s MX, Mino and AS3 impellers, totally dominating the competition!
Machined from Premium Alcoa 7075 T6-511 Aluminum ensures durability and stress resistance, over a life time of use.
Honda CR500 “phi” HV Impeller from MSV Racing Power Sports
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 a 1.5 avg. GPM more coolant flow along the entire rpm curve. The increase in 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 your engine is already making. Dyno testing showed up to 2.12hp FREED over a 1750 RPM range vs the competitors!
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 checkout the data. No other CR500 parts company will show you the proof they are the best. It’s the MSV Racing way!)
(Mino, Frank’s MX and AS3 are the SAME over-sized impeller with spacer)
NOTE* To ensure ease of installation each impeller comes with H2O pump cover gasket set (2 gaskets) for a seamless install.
