The Snow Performance Stage 2.5 Boost Cooler water methanol injection kit is suitable for all forced induction applications (Supercharged/Turbocharged). Using the VC-50 controller injects more or less water methanol as the pressure increases. The starting and exact points can be adjusted, thus creating a delivery curve that suits the engine's requirements. It provides a wide range of cooling and performance improvements and is particularly useful for direct injection engines to eliminate 100% carbon buildup in valves. Recommended for all street/strip vehicles using a turbo or centrifugal supercharger (Procharger/Vortech). The VC-50 controller offers the functionality of a boost gauge and water methanol controller in one. 7-color O-LED display shows boost, injection percentage, low level, secondary stage activation, prime button and system error codes. You can customize the color of the controller to match your OEM gauges. Uses the only OEM approved water methanol injection pump on the market. The 300 PSI UHO pump is designed to withstand the elements. Stage 2.5 comes with 100% methanol resistant components such as stainless steel, nickel plating, EPDM and hard anodization. Snow Performance ACU-SEAL compression fittings ensure leak-free operation. Supercharger, turbo or high compression engine, Stage 2.5 Boost Cooler cools the induction charge and boosts 91 octane fuel to 116 octane racing gas levels.
