MSV Racing chose the 1.8 bar (26 PSI) cap because it has proven to offer the best max system pressure to safety ratio.
This higher pressure reduces water pump cavitation, helps eliminate vapor barrier and hot spots/steam pockets in your cylinder head and around the cylinders exhaust port when you need it most! The cap also acts as high performance pressure valve ensuring maximum cooling from your system, while also acting as a safety valve warning you of possible engine danger.
The OptiFlo cap is the perfect complement to our MSV Racing “phi” Impeller. It is excellent insurance by keeping your precious coolant in the system even in the most demanding conditions. Together they offer unparalleled cooling!
Remember, horsepower = heat. 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 ride. Trust MSV Racing’s OptiFlo 1.8 Radiator Cap to help keep you at the head of the pack!
