BOOST COOLER
SYSTEMS

Maximum power and reduced emissions for your turbo diesel
The Boost Cooler Stage 3 TD water injection system by SNOW Performance enables a performance increase of up to 10–25% for turbo diesel engines without overloading the engine thermally. By cooling the intake air by up to 60°C and effectively lowering the exhaust gas temperature, thermal stress is reduced and torque is increased – ideal even for already tuned engines.

The advanced digital 2D controller has been designed to reduce specific fuel consumption in virtually all load conditions. The Stage 3 controller variably controls a small Boost Cooler injector across the entire power curve. This increases combustion efficiency, resulting in more power without increasing fuel consumption. The improved efficiency leads to better fuel economy. Typically, depending on the vehicle and driving style, fuel savings range from 5–15%.

Once the previously set load range on the LCD instrument is reached, the patented high-pressure pump injects finely atomised water or a water/alcohol mixture (methanol or ethanol) into the hot intake air. This evaporative cooling improves combustion efficiency and significantly reduces nitrogen oxide (NOx) formation.

With the integrated dual stage technology, two Boost Cooler atomising nozzles are used. The primary nozzle starts injecting early for temperature control, while the secondary nozzle is activated under high load. The result is enhanced cooling and maximum performance – ideal for towing vehicles and demanding applications on road and track.

STAGE 3 TD
CONTROLLER

The multiple award-winning Boost Cooler Stage 3 turbo diesel controller from SNOW Performance progressively controls the water or water-alcohol injection amount based on boost pressure and exhaust gas temperature. The desired start and full injection points are easily entered via the included LCD display. The controller then creates a 2D injection map for optimal injection across all load ranges. By using both boost pressure and exhaust gas temperature, the Stage 3 controller enables highly precise water-methanol injection control, especially for towing applications (caravans, motorhomes, trucks, etc.).

In addition to the primary nozzle, a second nozzle can be independently activated by the controller. – This ensures optimal use of cooling and performance in all turbo diesel load conditions. The progressive injection of water or water/methanol based on the 2D mapping is very precise and positively impacts cooling and engine performance across the widest possible engine load range.

PERFORMANCE

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

OPTIMAL COOLING

Water injection effectively cools the intake air through evaporative cooling, reducing the intake temperature by up to 60°C. This enables higher air density and more oxygen for combustion. Furthermore, combustion temperatures within the cylinder are lowered (in-cylinder cooling), leading to better performance and improved efficiency.

DUAL STAGE
TECHNOLOGY

Dual Stage injection – maximum performance under heavy load!
The Boost Cooler Stage 3 TD control unit is equipped with a second output, enabling control of an additional, larger nozzle (“Power Mode”). This second nozzle is activated depending on boost pressure and exhaust gas temperature, and can be flexibly configured to ensure maximum cooling and power delivery in high-load conditions. Included in delivery.

LOWER CONSUMPTION –
LOWER NOx

Integrating a water-methanol injection system in turbo diesel engines enables 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 is improved, with savings of up to 5–15%, depending on vehicle type, driving style, and application (e.g. towing vehicle).

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. Water injection also prevents temperatures in areas like the exhaust valves or piston zones from getting too high. Excessive heat encourages oil coking by burning and breaking down the oil faster. This cleaning effect is not only preventative but can also help reduce existing deposits (oil coking).

EASY INSTALLATION

To ensure a straightforward installation, all necessary fittings are included in the system’s package. The comprehensive installation manual in English, with many illustrations and a clear structure, guides you step-by-step through the process.
