Snow Performance VC50 OLED Gauge Controller – Water/Methanol Injection (WMI) Meth Kit Controller, Progressive Boost/MAP-Referenced, 52mm Gauge, Universal Turbo & Supercharged Petrol/Diesel – Boost Cooler Stage 2 (SP40150)

VC50 OLED Gauge Control Unit for Water Injection Systems

Part number: SP40150

Looking to stabilise intake temps, add detonation safety and keep power delivery consistent on a boosted setup? This Snow Performance VC50 control unit brings variable, pressure-referenced flow control to your water injection or water methanol setup, all in a compact 52 mm dash gauge. The VC50 reads manifold pressure and ramps injection smoothly across the load range, helping reduce charge air temperatures and improve knock resistance on both petrol and diesel forced-induction engines.

We have installed and used the VC50 at MJ Modifications and our customers love the tidy OEM-like gauge appearance, the quick setup and the precise, repeatable delivery. If you want a dependable, easy-to-tune controller for spirited road use and track days, this is a brilliant choice.

• Up to 3.5 bar boost capability, ideal for a wide range of turbo and radial supercharger applications
• 52 mm OLED gauge with 7 selectable colours for a clean, factory-style install
• On-screen readouts for pressure in bar, injection percentage, tank level, power nozzle status and fault codes
• Prime and pump test functions make setup fast
• Optional Dual Stage upgrade supports a dedicated high-load power nozzle for additional flow at full throttle
