Stage 2.5 Boost Cooler Forced Induction Progressive Water-Methanol Injection Kit (Nylon Tubing)

Establish the Benchmark, Raise the Bar, Repeat!

Unlock massive power and ultimate cooling for your boosted engine. If you are looking to push your turbocharged or supercharged vehicle to the next level, the Snow Performance Stage 2.5 Boost Cooler Water-Methanol Injection Kit is specifically engineered for forced induction applications. This advanced system can unlock an impressive 50 to 70 horsepower whilst drastically decreasing air intake temperatures by up to 100 degrees.

By effectively increasing your standard pump fuel octane rating by 25 points (transforming standard 91 octane into the equivalent of 116 octane race fuel), this kit allows you to safely make more power with a significantly cooler-running motor.

Intelligent Progressive Delivery with the VC-50 Controller

At the heart of the Stage 2.5 system is the advanced VC-50 controller. Housed in a sleek 52mm gauge design, it functions as a highly accurate boost gauge and a water-methanol controller in one compact unit. It progressively injects the precise amount of water-methanol mixture according to your manifold boost pressure. Because the start and full points are fully adjustable, you can perfectly tailor the engagement and delivery curve to match your engine’s exact requirements.

The VC-50 features a bright, customisable 7-colour OLED screen (Blue, White, Red, Yellow, Orange, Purple, and Green). It actively displays boost pressure, injection percentage, low fluid level warnings, secondary stage activation, and system fault codes. You can even mix and match colours to seamlessly integrate the gauge with your OEM dashboard dials!

Industry-Leading Pump and Leak-Free Hardware

Durability and reliability are paramount when dealing with injection systems. This kit features the only OEM-approved water-methanol injection pump on the market. The Extreme Environment 300 PSI UHO (Ultra High Output) pump boasts a proprietary heat flange, twin seals, and bespoke motor windings to run significantly cooler and longer than rival sleeve-style pumps. Fully sealed with O-ring connections, the pump internals are protected against moisture and corrosion, ensuring a long lifespan even in harsh engine bay conditions.

Combined with 100% methanol-resistant components—including stainless steel, nickel plating, EPDM, and hard anodising—the Stage 2.5 guarantees years of demanding use. The inclusion of Snow Performance’s robust ACU-SEAL compression fittings ensures absolute leak-free operation, even when running 100% pure methanol.

Perfect for Direct Injection and Forced Induction

Whether you are running a turbocharger or a centrifugal supercharger (such as Procharger or Vortech) on the street or the strip, this system provides unmatched cooling and driveability across a wide power band. Furthermore, it is incredibly beneficial for direct-injected engines; the atomised water-methanol mixture acts as a steam cleaner for the intake tract, actively removing 100% of carbon build-up from the intake valves.
