Description
Trusted by motorsport enthusiasts and performance drivers worldwide, SNOW Performance delivers proven water/methanol injection systems built for increased performance, reliability, and durability. Whether you’re chasing better performance on the track or smoother, more efficient driving on the street, SNOW Performance gives you race proven technology you can rely on under all conditions.
Snow Performance Boost Cooler Water/Methanol Injection Systems enable a power increase of up to 10–25% in turbo diesel engines, without thermally overloading the engine. By cooling the charge air by up to 60°C and effectively lowering the exhaust gas temperature, thermal stress is reduced and torque increased, ideal even for already tuned engines. As soon as the preset boost pressure is reached, the high pressure pump injects finely atomised water or a water/alcohol mixture (methanol or ethanol) into the hot intake air. This evaporative cooling leads to improved combustion efficiency and significantly reduces the formation of nitrogen oxides (NOx). The evaporating water in the combustion chamber also creates additional pressure on the piston, increasing torque and optimising power output. Integrating water/methanol injection into turbo diesel engines enables significant reductions in nitrogen oxides (NOx) and soot emissions. Studies show NOx can be reduced by up to 30% and soot by up to 70%, fuel efficiency also improves with savings of up to 5–15%.
Take full control of your water/methanol injection system with the Boost Cooler VC-50, integrated into an elegant 52 mm OLED gauge with a two colour display and seven selectable colour modes. It combines advanced performance features with precise water/methanol injection control, while providing real time system monitoring and diagnostics. The controller settings are configured directly via the 52mm instrument. The desired start and end values for boost pressure can be precisely defined here. Injection is then dynamically controlled within the specified boost pressure range. The Boost Cooler VC-50 control unit is equipped with a second output, allowing the activation of an additional, larger injection nozzle (Power Mode). The activation of this second nozzle is boost pressure dependent and can be flexibly configured to ensure maximum cooling performance and power delivery under high load conditions.
To ensure straightforward installation, all required connectors and fittings are included in the system. The detailed installation manual in English, with many illustrations and a clear structure, guides you step by step through the installation process.

Frequently Asked Questions
Why do turbocharged and naturally aspirated engines achieve more power with the Water/Methanol Kit?
The main problem of any internal combustion engine is the thermal load. In nearly all engines, the power is restricted by the temperature in the combustion chamber. If a certain temperature is exceeded, uncontrolled combustion (knocking) occurs. Uncontrolled combustion results in a massive loss of power and engine damage. In a turbo engine, this problem is compounded even further. The intake of the turbo engine heats up strongly in the turbine (through compression and heat transfer of the exhaust gases) and the thermal limit is quickly reached. In conventional turbo engines, this problem is typically addressed with the help of intercoolers.
The performance of a turbocharged engine is therefore directly dependent on the efficiency of the intercooler, as well as the cooling rate of the intake and charge air. The efficiency of intercoolers, however, is constrained by the ambient temperature and the maximum size of physical space constraints. An increase in boost pressure no longer produces more power and the damage to the engine is virtually inevitable. This issue can be solved using the Boost Cooler water injection concept. You can ensure additional cooling of the heated intake air through the injection of a water/alcohol mixture. The great advantage of the Boost Cooler is that the cooling is virtually unlimited in physical terms. That is, if the intake air is too hot, simply increase the injection volume to achieve the required level of cooling. This unique advantage can help fully exploit the capacity of turbo engines and the engine power is not restricted by the thermal limits.
Where can I mount my reservoir and pump?
The pump needs to be within about 60cm (hose length) of the reservoir, and as low or lower than the base of the reservoir. It is a “pusher” pump, not a “puller” pump. In the engine bay, the reservoir and pump can be placed almost anywhere, as long as they are not very close to exhaust heat, or in the path of debris from the road. Be sure that the pump is mounted at the same level or below the reservoir and that the reservoir is not located higher than the nozzle. If the reservoir must be located higher than the nozzle, a solenoid upgrade is required to prevent gravity feed. Boot mounting is also fine, but the pump needs to be close to the reservoir and gravity fed. Lengths of 6-7m of tubing to the nozzle are fine.
Which mixing ratio and what kind of water are used?
Use distilled or demineralised water, you can also use clean tap water when nothing else is available. Use methanol or bio-ethanol or isopropanol, a 50/50 ratio is recommended. This has been demonstrated to be the best for charge/air cooling, excellent detonation control, and safety. Do not use E85 or any other fluid with petrol mixed in, it will destroy the fluid delivery part of your Boost Cooler and instantly void the warranty.
