Description
The OptiFlosm KX500 “phi” HV Impeller, another must-have item for your KX500 engine.
There are only 3 ways to add extra cooling to your KX500:
- Bigger frontal radiator area. Not going to happen in the confines of the KX500 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 KX500 Impeller works its magic!
Rigorous flow bench and real-world MX race testing validated the MSV Racing’s “phi” impeller performance. Machined from 7075 T6-511 Aluminum for durability and stress resistance, the “phi” impeller dramatically improves your KX500’s H2O cooling and pumping performance over OEM, Frank’s MX, and AS3 impellers, totally dominating the competition!
The “phi” KX500 impeller vanes are computer-designed using “Golden Ratio” proportions based on the KX500’s H2O pump housing. This is in addition to closer tolerances between impeller and housing offer +1.2 average GPM more coolant flow. This increase in flow reduces the cycle time between the engine and the radiators allowing more heat removal quicker, lowering head and coolant temperatures up to 18*f when you need it most!
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, SuperMoto, or MX. Railing tight single track, sand dunes, or just love the latest KX500 impeller enhancement. 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 KX500 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 K500 impeller with spacer)
Note* To ensure ease of installation each impeller comes with an H2O pump cover gasket set for a seamless install.

Put this on my kx500 snowbike. Very impressed!! Saw a temp difference of 40 to 50

Jason’s Impeller design keeps both my CR500 and KX500 cool in the AZ Deserts. A temp gun on the radiators shows a considerable cooling over stock.

I received the package quickly. impeller definitely makes the bike run noticeably cooler!

Price was good and competitive.

Jason, finally got around to starting my KX500 with your precision machined high flow impeller. I did not measure the flow rate of the cooling system with your impeller, but from looking in the radiator with the engine running I can see it does have significantly more flow (turbulence in the radiator) over the stocker. It’s almost like a “tempest in a teapot”. Based on that perception and measuring the clearances to the impeller housing with your impeller and the stocker, it is easy to conclude your impeller will flow more coolant and cavitate less than the stocker. From a visual comparison of the two impellers yours is more “hydrodynamically” designed, the machining is excellent and the visual appearance is outstanding over the stocker. It is a shame that a part this good is going to be covered up by the impeller housing. When the weather clears up and my surgery heals I will be doing some extended radiator temperature testing. Really good work!!

My thoughts on the impeller after testing on my Super Moto and both my Land Speed bikes is that NOTHING cools better than the MSV Racing PHI impeller… 2 miles, 5th gear pinned… high port timing… Zero overheating and I’ve been running without shrouds. The harder you push your bike the more you need it..
