MSV Racing OptiFlo 1.8 Radiator Cap—Maximize Cooling Performance For Your Ride!
When it comes to keeping your high-performance engine running at peak efficiency, cooling system management is critical. MSV Racing has chosen the OptiFlo 1.8 bar (26 PSI) Radiator Cap to ensure safe system pressure, optimizing coolant circulation and heat dissipation when you need it most.
Why Did We Choose a 1.8 Bar Cap?
🚀 Superior Pressure-to-Safety Ratio
- A higher system pressure prevents water pump cavitation, eliminating air pockets, vapor barriers, and steam pockets that form in the cylinder head and exhaust port when you need it most.
- This cap functions as a high-performance pressure valve, reducing the chance of coolant boiling while providing an early warning system for potential overheating risks.
🔥 Pair with the MSV Racing “Phi” Impeller for Elite Cooling
- Designed to complement our MSV Racing “Phi” High Flow Impeller, ensuring your coolant remains fully contained even in extreme conditions.
- Together, the OptiFlo Cap + Phi Impeller deliver unparalleled cooling efficiency, giving you the edge in demanding riding scenarios.
⚡ HEAT = Horsepower
- More horsepower generates more heat—and the better your cooling system handles that heat, the more power your engine can sustain.
- With increased cooling ability, your engine operates at optimal temperatures, allowing for higher efficiency and prolonged durability.
