Snow Performance Boost Cooler Stage 2E Power-MAX Universal Water Methanol Injection Kit | Turbo & Supercharged Petrol/Diesel | VC50 52mm OLED Gauge | 300 PSI Pump | SP10250

Power-MAX Stage 2E Water-Meth System with VC50 Gauge Controller — SP10250

Add safe, repeatable horsepower and combat heat soak with this universal water injection system for boosted engines. The Stage 2E Power-MAX kit delivers progressive, boost-referenced fluid delivery using the compact 52 mm VC50 OLED gauge controller. Ideal for petrol and diesel forced-induction builds, this charge cooling solution helps lower intake charge temperatures, tame detonation and unlock the headroom your tune deserves.

We have fitted and used this package on customer cars and on our own projects with excellent results. Owners consistently praise the smooth ramp-in, tidy OEM-looking gauge, and the way the car pulls harder for longer. If you are searching for a water injection kit UK, water meth kit UK, methanol spray system for turbo cars or a charge cooling upgrade for remapped engines, this is the proven pick.

Standout benefits

• Boost-referenced progressive control for turbo and supercharged applications
• 52 mm OLED gauge controller shows and sets boost in bar or PSI with simple menu navigation
• Ultra high output 300 psi diaphragm pump for consistent fine misting and rock-solid delivery
• Hypersonic atomising jets for efficient charge cooling and even distribution
• Optional Dual Stage Technology for independent two-nozzle maps — upgrade part SP10350
• Meaningful performance potential on boosted engines with sharper response and stronger mid-range
• Intercooling effect with substantial intake temperature drops for reliable, repeatable power
• Octane-on-demand effect that supports safer ignition timing on 95 RON
• Helps reduce EGT and oil temperature while suppressing knock under high load
• No airflow restriction or pressure drop like a conventional intercooler add-on
• Steam-cleaning effect can help reduce carbon on valves and in combustion chambers
• Universal fit for performance petrol and diesel vehicles, road or track

How it enhances your build

The Stage 2E controller varies flow in proportion to manifold pressure, so charge cooling scales with boost. You set the start and full points to match your tune, turbo size and fuel quality. Water’s high latent heat absorbs combustion heat, increasing charge density and helping prevent detonation, while the methanol blend adds an octane effect for more stable power delivery on aggressive boost targets.

The Europe Edition VC50 displays and programs in bar as well as PSI for straightforward setup in the UK and EU.

What is included

• 300+ psi high-pressure pump
• VC50 52 mm OLED progressive gauge controller
• Two nozzles with fittings and holder
• 3 litre reservoir with low-level sensor, LED and grommet
• 1/4 inch nylon hose, approximately 3 metres
• 90 degree steel nozzle holder
• Complete hardware and instructions

Recommended add-ons

• Dual Stage Technology controller upgrade — SP10350
• Larger tank option — 9.5 litre reservoir for extended range between fills

Compatibility and typical use

Suits turbocharged and supercharged engines across petrol and diesel platforms. Especially effective on remapped forced-induction cars where progressive, boost-based control is preferred. For positive displacement blowers such as Eaton or Twin Screw, and for very small, fast-spooling turbos, consider airflow or MAF-referenced kits for best resolution.

Popular on BMW turbo engines including N20, N54, N55, S55, N63, N63TU, M57, B38, B48, B58, S63 and S63TU. Common search terms include B58 meth kit, N54 water injection, N55 methanol system and S55 charge cooling.

Real-world gains our customers notice

• Lower intake temps for consistent lap-after-lap performance
• Improved knock resistance that supports safer boost and timing
• Reduced thermal stress on tuned engines and heavy-use trackday cars
• Smoother drivability thanks to accurate, progressive fuelling under boost

Installation and setup

Configure start and full points on the VC50, then fine-tune to your calibration and fuel quality. With the optional Dual Stage Technology upgrade you can run a second nozzle map for sustained high load.
