Boost Cooler Water Injection Systems – the chemical intercooler

Over the years, Snow Performance has become the world´s leading manufacturer in Water-Methanol Injection Systems. Each system has been designed and tested by engineers to ensure reliability and robustness.

Water Injection is not new. During WW2, water injection was extensively used on both Allied and Axis aircraft. In the 1980s, Ferrari and Renault adopted water injection on their F1 turbo engines. Up until a few years ago (when it was banned), most World Rally Championship cars used water injection systems.

More Power
By using the Boost Cooler, you can expect up to approx.10-20% more power on charged gasolines engines, 15-25% on Turbodiesels and up to 5-15% on naturally aspirated gasoline engines. – Even on pre-tuned engines.

The Boost Cooler injection works in three ways: Firstly, when water is injected into the intake system prior to the cylinder head, the small droplets absorb heat from the intake air. ​Next, the small droplets of water start to evaporate. And so the intake air charge is cooled still further (up to 60°C and more). ​Finally, when the remaining water droplets and water
vapour reach the combustion chamber, steam is produced. When the water changes from the liquid to gas state, large amount of heat energy is consumed in sustaining the process. The latent heat of evaporation is 2256kJ/kg, approx. six times more than gasoline.

This chemical process acts as an anti-detonant and also keeps the interior of the engine very clean, so preventing the build-up of carbon “hot spots”. So water is the perfect liquid for regulating excess heat under certain engine-operating conditions and you´ll cool down your EGT, the valves, pistons and turbocharger!

Race Gas Performance
Methanol (alternately Ethanol) with a high octane value added into it both reduces the knocking tendency and improves the cleaning effect within the combustion chamber. It is also used as antifreeze and prevents limescale deposits. The injection of a water/methanol mixture together with 95-octane gasoline is similar in effect to high-priced 116-octane racing fuel

Many successes in motorsports were achieved by using the Boost Cooler Water-Methanol Injection Systems.
Among others, two 1/4miles Diesel Dragster world-records, different topspeed world-records for street-legal cars in 2005, 2006, 2008, 2009 and 2013 on VW, BMW, Porsche and Ford. Nowadays even the premium manufacturer BMW M is using water injection to increase horsepower and reducing the fuel consumption in their BMW M4 GTS.
