MSV Racing “OptiFlo” ’89-’01 CR500 Cooling Power Package

Making more horsepower is all the rage but an often-forgotten part of making more horsepower is how to keep the engine cool.

If you look at the competition’s cooling parts you can tell they are not taking the cooling of your CR500 engine seriously.

After extensive development this is where MSV Racing steps in to provide premium upgrades to ensure your keeping your CR500 cooling needs in check reducing engine temps by up to 23ºF. 

Buy these parts individually or in a reduced cost package

Available in Shiny billet or Military Spec (MIL-A-8625) Black Anodized and Red Anodized finishes.

CR500 Cooling Power Package Contains:

OptiFlo “phi” High Volume Impeller. Our impeller is the heart of this package. No other CR500 impeller comes close to the flow of our impeller. +1.5 avg. GPM more coolant flow along the entire rpm curve. Take a look at the cooling testing on the CR500 Impeller page.

OptiFlo High Flow H2O Pump Cover. The MSV Racing H2O Cover is by far the most efficient cover you can buy for your CR500. After you look at the cut away and flow graph, why would you choose any other cover? Fully radiused interior for less turbulence, reduced back pressure, and far superior flow vs OEM and billet replicas. Offering +1.3 GPM AVG more coolant flow vs OEM and billet replicas. Cover is O-ringed to eliminate both gaskets and separator plate

OptiFlo High Flow Elbow.  4 reasons why this elbow has no competition. Check out the CR500 Elbow page for pics of each of these enhancements.

-Fully radiused interior VS sharp 90* turn with minor corner fillet.

-Elbow to cylinder coolant port aligned correctly VS misaligned from the factory. -Pivoted to point directly at the H20 pumps discharge port VS spigot not in line with the H20 pump port. -Spigots lead in profile is tapered VS Squared edge for laminar flow from hose to spigot.

All 4 of these reduces back pressure by +1 PSI allowing any CR500 impeller to be more efficient.

OptiFlo 1.8 Rad Cap. To “Cap Off” this Cooling Power Package we provide you the best max system pressure to safety ratio.
