SNOW PERFORMANCE BOOST COOLER SYSTEMS

Maximum power and reduced emissions for your turbo diesel
The Boost Cooler Stage 2.5 TD water injection by SNOW Performance enables 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.

The new Boost Cooler Stage 2.5 TD system is designed for all turbo diesel engines up to 3.5 bar boost pressure and offers excellent value for money. As with the Stage 2 and Stage 3 systems, the injection quantity is electronically regulated via boost pressure and offers optimised, variable injection control compared to the Stage 1 system.

Once the previously set boost pressure is reached on the 52mm OLED gauge, the patented high-pressure pump injects finely atomised water or a water/alcohol mix (methanol or ethanol) into the hot charge air. This evaporative cooling results in improved combustion efficiency and significantly reduces nitrogen oxide (NOx) formation.

With the optional Dual Stage upgrade, two Boost Cooler atomising nozzles are used. The primary nozzle begins injection early for temperature control, while the secondary nozzle is activated under high load. The result is enhanced cooling effect and peak performance – ideal for demanding road and track applications.
