Complete water-methanol injection starter kit for turbo and supercharged petrol engines. The Stage 1 is the entry-level Boost Cooler — simple, effective, and upgradeable. The system activates at a user-set boost pressure and injects a fixed amount of fluid until boost drops below the threshold. Expect 10–20% more power with cooler intake temps and knock-free combustion.

What's in the Box

• 300 PSI EPDM high-pressure pump (100% methanol-resistant, double-sealed)
• Hyper-Sonic™ injection nozzle(s) — sized to your engine's power level, with integrated 100-micron filter
• Adjustable boost-pressure switch (sets activation point)
• 3-litre reservoir (black) with pump mount
• All fittings, pressure lines, and mounting hardware
• Comprehensive installation manual with dyno test reports

Key Features

• Injection type: Fixed-rate, boost-referenced on/off
• Control: Adjustable pressure switch — set your activation point, system does the rest
• Engine compatibility: Any turbo or supercharged petrol engine (fuel injected or carbureted)
• Power gains: Up to 10–20% on tuned engines — equivalent to running 116-octane race fuel
• Upgradeable: Add a Stage 2 or Stage 3 controller later without replacing pump, tank, or nozzles

How It Differs from Other Stages

Stage 1 uses a simple on/off pressure switch — when boost hits your set point, injection starts at a fixed rate. It's the most affordable way into water-meth injection. For variable injection that adjusts flow with boost pressure, step up to Stage 2. For 2D mapped injection (boost + fuel data), go Stage 3.
