Snow Performance Boost Cooler Stage 2E ProLine Water Methanol Injection Kit - Universal Meth/Water WI for Turbo & Supercharged Petrol/Gasoline & Diesel - VC50 52mm OLED Gauge Controller, 300 PSI Pump, Hyper-Sonic Nozzles, 3L Tank - SP10250PRO

Snow Performance ProLine Universal Stage 2E Power‑Max Water Meth Kit

Part Number: SP10250PRO

Looking to drop intake temps, add safe power and protect your engine under load. This Snow Performance ProLine Stage 2E Power‑Max water injection system is the proven, go‑to solution for forced‑induction builds. With a compact VC50 OLED gauge controller, a serious 300 psi UHO pump, Hyper‑Sonic atomising nozzles and robust steel braided hose, it delivers crisp, reliable charge cooling on boosted petrol and diesel applications. Ideal for daily drivers, track cars and towing rigs that need consistent performance even in hot conditions.

We run this exact setup on customer cars and our own development vehicles. Results are repeatable. Expect noticeably cooler IAT, smoother delivery, stronger mid‑range and the confidence to run the calibration your hardware deserves. Owners love the extra knock resistance, cleaner combustion and the way it keeps power consistent pull after pull.

Key benefits

• Progressive water meth control referenced to boost for seamless delivery and smooth drivability
• VC50 52 mm OLED display shows boost in bar, tank level and injection flow for easy monitoring
• Typical gains of up to 10 to 25 percent on turbo and supercharged setups when calibrated correctly
• Large IAT reduction, commonly up to 60°C, for denser charge air and more ignition timing headroom
• Octane effect comparable to high race fuel while using normal 95 RON petrol
• Helps cut EGTs and oil temps for safer, repeatable performance under sustained load
• Enables safer additional boost and timing on petrol and diesel engines
• Steam‑cleaning action can reduce carbon deposits on valves, seats and piston crowns
• No pressure drop penalty like oversized front mount only solutions
• ProLine steel braided line included for durability and an OEM‑plus installation finish

Controller and injection hardware

• VC50 gauge controller with bright, 7‑colour OLED screen and progressive mapping
• Set start and full points to match your car’s boost curve for dialled‑in delivery
• Dual Stage capable. Add the optional upgrade (SP10350) to control two nozzles independently
• Ultra‑High Output diaphragm pump, 300+ psi, for fine atomisation and consistent spray
• Hyper‑Sonic nozzles for precise metering and superior in‑manifold intercooling effect

Fitment and tank options

Universal kit for turbocharged and supercharged petrol and diesel engines operating up to around 30 psi of boost. V‑configuration engines with separate banks should run one nozzle per intake path. Supplied with a compact 3 litre reservoir for clean installs. For extended range, larger 9.5 litre and 26.5 litre tank upgrades are available.

Note for positive displacement blowers such as Eaton or Twin Screw, and for very fast‑spooling small turbos like K03 or K04, the Stage 2 MAF or Stage 3 variants may suit better.

What you get in the box

• UHO 300+ psi high‑pressure pump
• VC50 52 mm OLED gauge controller
• Two Hyper‑Sonic nozzles
• 3 litre reservoir with low‑level sensor, LED and EZ‑fit grommet
• ProLine steel braided line, 3 metres
• 1/4 inch 90 degree steel nozzle holder
• All required fittings, wiring and mounting hardware
• Full installation instructions

Compatibility

Universal for most boosted platforms. Popular on BMW N20, N54, N55, S55, B38, B48, B58, N63, N63TU, S63 and S63TU, plus a wide range of VAG, Ford EcoBoost, Mercedes‑AMG, Subaru STI, Mitsubishi Evo, Toyota GR, VW TDI and other turbo or supercharger builds. If your engine makes boost, this kit is designed to integrate.

Real‑world results with MJ Modifications

Installed, tested and tuned by our team, this system consistently delivers lower charge temps, knock control, stronger mid‑range torque and repeatable performance on hot days and during back‑to‑back runs. Our customers rate the reliability, the tidy install and the easy‑to‑use controller.

Professional fitting and setup

The VC50 makes initial setup straightforward. Choose the boost point for injection to begin, set your full point and let the controller vary flow progressively between those values.
