Boost Cooler Stage 2 Water Injection

Electronically controlled water/alcohol injection incl. LCD display and 20 bar pump system!

The Stage 2 Boost Cooler progressively injects more or less water or water/alcohol, according to manifold boost pressure (MAP sensor included). The system can be set in seconds using the LCD programming unit supplied.

BOOST COOLER STAGE 2 ADVANTAGES AT A GLANCE

Electronic control: The VC-30 controller dynamically adjusts the Boost Cooler injection rate according to boost pressure.
LCD programming unit: Separate display with real-time boost and injection rate monitoring.
Performance boost: Higher boost pressure and/or earlier ignition timing – power increase of up to 20% possible.
Thermal relief: Effectively reduces thermal stress in already modified engines such as those with chip tuning, LPG/autogas, NOS, or increased boost pressure.
Efficient charge air cooling: Reduces intake air temperature by up to 60°C without boost loss, unlike conventional intercoolers.
Fuel savings: Reduced specific fuel consumption due to optimised combustion process.
Eco-friendly: Reduction of CO2 and NOx emissions.
Engine care: Cleaner combustion chamber and intake system – no carbon deposits or buildup.
Universally applicable: Suitable for all turbo/supercharged engines up to 2.1 bar boost pressure.
Easy installation: Includes all necessary components for trouble-free setup.

SNOW PERFORMANCE BOOST COOLER SYSTEMS

Maximum power and reduced emissions for your turbo engine
The Boost Cooler Stage 2 water injection from SNOW Performance enables a performance increase of up to 10–20% in turbocharged and supercharged engines, without causing thermal overload. By cooling the charge air by up to 60°C and effectively lowering the combustion temperature, thermal stress is reduced and performance enhanced – ideal even for already tuned engines.

The new Boost Cooler Stage 2 system is designed for all turbo and centrifugal supercharger engines up to 2.1 bar boost pressure and offers excellent value for money. Like the Stage 2.5 and Stage 3 systems, the injection rate is electronically regulated via boost pressure and offers optimised, variable injection control compared to the Stage 1 system.

As soon as the previously set boost pressure is reached (via LCD screen), 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 and the vaporisation process within the engine lead to improved combustion efficiency, preventing uncontrolled combustion ("knocking"). The effect is proven to be comparable to 116-octane racing fuel.

Another benefit is the steam expansion effect: The evaporating water in the combustion chamber generates additional pressure on the piston, increasing torque and optimising power output. This technology has already been successfully used in aviation to improve engine efficiency.

VC-30 CONTROL UNIT WITH MAP SENSOR

VC-30 controller – precise boost-based injection control
More power, less hassle: The VC-30 control unit with external MAP sensor controls water-methanol injection precisely via boost pressure – ultra-fast and fully automatic. Setup is simple: enter boost pressure, done. The separate smart LCD screen constantly displays system status, boost pressure, and pump output.

The LCD display can be installed in the driver's line of sight if desired. The control unit is splash-proof and can be flexibly mounted in the engine bay or vehicle interior.

Recommended for all turbo/supercharged engines up to 2.1 bar boost pressure.
