BOOST COOLER
SYSTEMS
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 charge air temperature is lowered by up to 60°C, the combustion chamber is cooled and the thermal load on already tuned vehicles 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.
VC-30 CONTROLLER
INCL. MAP-SENSOR
The included control unit varies the injection quantity, with a reaction time of 1.5msek, flexibly to the boost pressure. The settings on the LCD screen can be made within a few seconds without prior knowledge. You only set the boost pressure (start/full) - the system does the rest for you.
The VC-30 control unit can be placed in the engine compartment or inside the vehicle, protected from splash water. The LCD display can be installed in the field of view if required and provides general information about the status of your system (boost pressure display as well as pump performance).
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.
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.
OCTANEBOOSTER
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.
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.
MOTORSPORTS KNOW-HOW
As an OE supplier and through its activities in a wide range of motorsport areas, SNOW Performance proves the quality and durability of the high-quality water injection systems "Made by SNOW PERFORMANCE".
Pressure Diaphragm Pump
SNOW Performance 300 PSI UHO methanol injection pumps offer unmatched pressure, technology and reliability. All 300 PSI 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.
Hyper-Sonic Injection nozzles
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.
3l Reservoir with Fluid Level Switch
Boost Cooler water injection 3l tank with separate level indicator and warning LED (orange) for installation in the vehicle interior. 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.

Frequently asked questions
Why turbo / naturally aspirated engine achieves more power with the Boost Cooler?
The main problem of any internal combustion engine is the thermal load. In nearly all engines, the power is restricted by the temperature in the combustion chamber. If a certain temperature is exceeded, uncontrolled combustion ("knocking") occurs. 
Uncontrolled combustions results in a massive loss of power and engine damage. In a turbo engine, this problem is compounded even further. The intake of the turbo engine heats up strongly in the turbine (through compression and heat transfer of the exhaust gases) and the thermal limit is quickly reached. In conventional turbo engines, one tries to get this problem solved with the help of intercoolers.
The performance of a turbocharged engine is therefore directly dependent on the efficiency of the intercooler, as well as the cooling rate of the intake and charge air. The efficiency of intercoolers, however, is constrained by the ambient temperature and the maximum size of tight physical limits. An increase in boost pressure no longer produces more power and the damage to the engine is virtually inevitable. This issue can be solved using the Boost Cooler waterinjection concept. You can ensure additional cooling of the heated intake air through the injection of a water / alcohol mixture. The great advantage of the Boost Cooler is that the cooling is virtually unlimited in physical terms. That is, if the intake air is too hot, simply increase the injection volume to achieve the required cooling degree. This unique advantage can help fully exploit the capacity of turbo engines and the engine power is not restricted by the thermal limits.
Does the Boost Cooler cause any damage to my engine?
No. At a relative humidity of 50% and ambient temperature of 25° C, a turbocharged engine consumes (2.0 l displacement, 1 bar boost pressure) approx. 160 ml of water per minute. For example, if a gasoline engine is used, the combusted air / fuel mixture consists of approximately 50% of water vapour and carbon dioxide. 
With the injection of 250 ml/ min of water per minute at full load, the Boost Cooler accounts for less than 1.6% of the exhaust gases Horror scenarios ("water hammer", rusting motors, etc.) that some of you might have read on the Internet tuning forums are only based on a lack of understanding of the technical writer or improper systems.
Study of Porsche Engineering (excerpt): “The technology of water injection into the intake manifold provides significant potential. This technology can use a stoichiometric air-fuel ratio in the entire operating area and an optimal ignition timing to increase the efficiency of the engine. In addition to a further reduction in fuel consumption, this effect also reduces the compression work so that the engine displacement can be further reduced."

Where can I mount my reservoir and pump?
The pump needs to be within about 60cm (hose length) of the reservoir, and as low or lower than the base of the reservoir. It is a “pusher” pump, not a “puller” pump. In the engine bay, the reservoir and pump can be placed almost anywhere, as long as they are not very close to exhaust heat, or in the path of debris from the road. Be sure that the pump is mounted at the same level or below the reservoir and that the reservoir is not located higher than the nozzle. If the reservoir must be located higher than the nozzle, a solenoid upgrade is required to prevent gravity feed. Trunk mounting is also fine, but the pump needs to be close to the reservoir and gravity fed. Lengths of 6-7m of tubing to the nozzle are fine.
Which mixing ratio and what kind of water are used?
Use distilled or demineralised water only. Distilled water is available in any hardware store (about € 1.50 for 5 litres) or gas station. Of course you can also use clean tap water when nothing else is available at the moment. Use methanol or bio-ethanol (approx. 45 € per 30 litres, including shipping), or isopropanol. A 50/50 ratio is recommended. This has been demonstrated to be the best for charge/air cooling, excellent detonation control, and safety.
Do NOT use E85 or any other fluid with gasoline mixed in. It will destroy the fluid delivery part of your Boost Cooler and instantly void the warranty.
How much range will a tank of Water/Methanol provide?
This depends on a number of variables. HP, injection system, settings, driving style, etc. For most gasoline engines in the 200-250hp range, the standard 3l tank will last around a tank of gasoline when driving on the road. Diesels use more fluid than a gasoline application, and are in heavier load states more often. Due to the higher consumption of liquid in turbodiesels and/or powerful gasoline cars, we recommend at least our 9.5 l or 26.5 l trunk mounting kit as needed.
Where can I mount the nozzle?
The best placement of the nozzles is in the area around the inlet to the intake manifold or virtually anywhere on the pipe leading from the intercooler to the intake manifold. The nozzles can be placed at any position on the tube, so long as they are pointing at a 90 degree angle to the direction of airflow. The nozzles can be placed in a series or right next to each other.
There is enough heat and velocity and flow through the pipe under boost to absorb the water/methanol regardless of the nozzle positions relative to each other. Placement before the intercooler or turbo(s) is not recommended. Cooling is not improved. Never mount an injector nozzle before a turbocharger compressor. Studies performed by SAAB, concluded that pre-turbo injection will over time cause cavitation on the turbo wheel leading edges.
Do I need to activate the Boost Cooler in some way?
The Boost Cooler will activate automatically. Depending on the system, it activates after receiving a pre-set boost pressure or engine load signal, and then starts injecting in a load-dependent manner.
Do I need an intercooler with the Boost Cooler?
Up to approximately 2bar of boost, water/methanol injection (using 50% methanol) will provide all the density increase/detonation control needed in most applications. Of course, intercooling and water/methanol injection would provide even greater benefits, especially beyond 2bar of boost.
Most air-to-air intercoolers are only 50-65% efficient. For example, with 0.75 bar of boost and the resulting 50°C air charge temperature increase, an intercooler reduces the air charge temperature only 25 degrees. Also, an intercooler will reduce boost 0.1-0.25bar on average.
