Award-Winning Water Methanol Injection System - our high-end model for every engine with direct injection.

The Boost Cooler Stage 3 DI Controller creates a 2D-delivery map based boost and fuel pressure sensor voltage. Easy programmable LCD-display with new Dual Stage Injection Technology.

Ideal for all turbo-/supercharged engines with direct injection (VAG TSI/TFSI, PSA THP, Ford/Opel Ecotec etc.).

Boost Cooler water injection can achieve a power increase of up to 10-25% in turbo and supercharged engines without thermally overloading the engine. The intake air temperature is lowered by up to 60°C, the combustion chamber is cooled and the thermal load on already tuned engines is effectively reduced.

Water or water/alcohol (methanol or ethanol) is injected at high pressure into the hot charge air in a finely atomised form as soon as the desired starting charge pressure is reached. The evaporating liquid achieves an extremely effective charge air and intercooling, which, among other things, prevents uncontrolled combustion ("knocking"). The effect is demonstrably comparable with 116 octane racing petrol.

The Boost Cooler is unsurpassed in atomisation! The liquid is swirled inside the Hyper-Sonic atomiser nozzle at supersonic speed before being forced through the Venturi orifice. With the included Dual Stage Upgrade, 2 atomiser nozzles are used to inject as early as possible with the primary nozzle and to achieve maximum cooling and performance in peak loads with the switched-on 2nd nozzle.

STAGE 3 DI CONTROLLER

The multi-award winning Boost Cooler Stage 3 DI control unit from SNOW Performance regulates the water or water-alcohol injection quantity progressively to the boost pressure and the fuel injection quantity (fuel pressure sensor signal). The desired start and full injection times are simply entered in the enclosed LCD screen. The controller then creates a 2D injection curve for the optimum injection quantity in all load ranges. By using boost pressure and the fuel pressure sensor signal, the Stage 3 controller enables very precise water-methanol injection quantity regulation.

In addition to the primary injector, another injector, independent of the primary injector, is optionally controlled by the control unit. - This ensures optimal use of cooling and power in all load ranges of the engine. The progressive injection of water or water/methanol based on the 2D mapping created is very precise and has a positive effect on cooling and engine performance over the widest possible engine load range.

OPTIMAL COOLING

In contrast to a conventional intercooler, the charge air can be lowered below the ambient temperature! In addition to the outstanding efficiency, there is no loss of boost pressure as with conventional performance intercoolers. The Boost Cooler efficiently cools the intake air and combustion chamber temperature ("in-cylinder-cooling"). The addition of alcohol (preferably methanol or inexpensive bio-ethanol) additionally increases efficiency and counteracts lean running.

PERFORMANCE

With the Boost Cooler, you can achieve a power increase of about 10-25%, even with already tuned turbo and supercharged engines. The optimum cooling compensates for typical power losses at higher outside temperatures. In addition, deposits in the combustion chamber and intake tract are reduced.

DUAL STAGE TECHNOLOGY

The controller has a 2nd output to control a further, larger nozzle with a separate mapping ('Power Mode'). The connection of the 2nd nozzle can be set individually to achieve the best possible performance results.

OCTANE BOOSTER

In combination with super petrol and a water/methanol mixture, you achieve a comparable effect as with 116-octane racing petrol. This also allows you to dispense with the considerably more expensive Shell "V-Power", "Ultimate 100", etc. and drive only with conventional super gas.

LESS CONSUMPTION - LESS CO2

The better efficiency improves fuel economy. As a rule, fuel savings are in the range of 5-15% depending on the vehicle, driving style and use (e.g. tractors).

The NREL test result clearly shows that NOx emissions are significantly reduced with the Boost Cooler System activated. As a positive side effect, the DPF regeneration cycles are extended due to the lower pollutant emissions.

LESS DEPOSITS IN THE COMBUSTION CHAMBER

The combustion chamber of your engine remains free of deposits, the heat dissipation, e.g. at the exhaust valves, remains optimal. Oil coking is reduced and prevented.

EASY INSTALLATION

To ensure a smooth installation, all connection materials are included in the scope of delivery of the system. The detailed installation instructions in German, with many illustrations and a clear structure, guide you step by step through the installation process.

SNOW Performance 300 PSI UHO methanol injection pumps offer unmatched pressure, technology and reliability. All Boost Cooler diaphragm pumps are made in the USA and individually tested before shipping to ensure quality and reliability. Although similar looking pumps are available, they do not have the features of our SNOW Performane pumps.

Double EPDM seals ensure durability and higher pressure. Proprietary internal wiring offers lower power consumption than similar looking pumps. Integrated thermal protection circuitry allows the pump to operate constantly without damaging pump internals.

The SNOW Performance HyperSonic atomiser nozzle is the world's best-selling and most advanced water/alcohol injection nozzle. The liquid is swirled inside the patented 2-chamber nozzle at supersonic speed before being forced through the Venturi orifice. This creates droplets or mists as fine as 20µ (microns) with enormous cooling potential.

The principle of evaporative cooling is a highly efficient technology and effectively reduces the intake or charge air temperature. Likewise, evaporation processes within the engine reduce the thermal load.

With the "reserve light" you can be sure never to operate your water-methanol injection without sufficient fluid. Completely incl. connection for 1/4" pressure line.

To extend the range of the water injection, you can upgrade this system to a tank with a capacity of 9.5l or 26.5l. To do this, simply configure the desired tank size.

The settings on OLED control unit can be made within a few seconds without any prior knowledge. The only thing you need to determine is at what boost pressure the injection is to begin and what the maximum boost pressure is. - The variable injection of the Boost Cooler is performed within these two preset boost pressure points. By using the optionally Dual Stage Technology, you´re able to set a 2nd nozzle mapping for optimized injection quantity especially at higher engine load states.
