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.

VC-50 CONTROL UNIT
WITH OLED DISPLAY

VC-50 – Precision control at its finest
The Stage 2.5 system is the consistent evolution of our successful Stage 2 kits, developed to production readiness in cooperation with our sales and technology partners. The VC-50 controller, housed in a 52mm OLED round gauge, features a two-colour display, 7 freely selectable colour modes, and provides all critical system data at a glance – stylish and functional.

Intuitive control directly via the display
Boost pressure values can be set precisely and easily on the display. Injection responds dynamically and ensures consistent performance with high efficiency. Real-time data such as boost pressure (in BAR), injection quantity, fluid level or error messages make the setup transparent and safe.

Recommended for all turbo diesel engines up to 3.5 bar boost pressure.

PERFORMANCE

With the Boost Cooler Stage you’ll achieve a noticeable power increase of up to 10–25% – even with already tuned turbo diesel engines. Injecting a finely atomised water or water/alcohol mixture into the charge air improves oxygen density in the combustion chamber. The result: greater efficiency, more torque and clean, controlled combustion.

OPTIMAL COOLING

Water injection effectively cools the charge air via evaporative cooling, reducing the charge air temperature by up to 60°C. This allows for higher air density and more oxygen for combustion. Additionally, combustion chamber temperature is lowered (in-cylinder cooling), improving performance and efficiency.

DUAL STAGE
TECHNOLOGY

Dual Stage Upgrade – maximum performance under heavy load!
The Boost Cooler VC-50 controller is equipped with a second output which allows the activation of an additional, larger injection nozzle (“Power Mode”). This second nozzle is engaged depending on boost pressure and can be flexibly configured to ensure maximum cooling effect and performance development in high-load conditions. (Optional, upgrade SP10350 required).

 

LOWER CONSUMPTION –
LOWER NOx

Integrating a water-methanol injection system into turbo diesel engines allows for significant reductions in nitrogen oxide (NOx) and soot emissions. Studies show that NOx emissions can be reduced by up to 30% and soot particles by up to 70%. At the same time, fuel efficiency improves, with savings of up to 5–15%, depending on vehicle type, driving style, and usage (e.g. towing).

LESS DEPOSITS IN THE COMBUSTION CHAMBER

Thanks to cleaner combustion with the Boost Cooler, fewer soot particles and carbon compounds are produced that could lead to deposits. Additionally, the water injection prevents excessively high temperatures in areas such as the exhaust valves or piston region. High temperatures promote oil coking as they accelerate the burning and breakdown of oil. This cleaning effect is not only preventive but can also help reduce existing deposits (oil coking).

EASY INSTALLATION

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.
