Snow Performance

The Boost Cooler® is Snow Performance's latest generation water/methanol injection system. The primary function of water/methanol injection is to provide "chemical intercooling".

In gasoline engines, as with any intercooler, this suppresses detonation so more power producing boost and timing can be utilized. Water, with its high latent heat of vaporization cools the intake charge and combustion. Methanol cools the charge and combustion but also acts like an extremely high octane fuel (some researchers claim as high as 120 octane) as well as adding more oxygen to combustion.

In diesels, the effect is three fold: 1. The intercooling effect provides for more available air and all the benefits of a higher positive pressure ratio (more power giving fuel can be utilized safely without high combustion temperatures). 2. The combustion of water provides for more power on the power stroke. 3. Methanol acts as an additional fuel for more power.

Diesel Engines

What are the benefits of Water/Methanol injection?

  • Greatly reduced EGTs - Decreases of 250 degrees F are common using a 50/50 water-methanol mix. Increased EGTs are an engine killer in today's performance diesel world.
  • Low cost power - Where else can you get 70-100 HP for as low as $469?
  • Greatly increased air charge densities - 3-5 psig boost increases are common.
  • Great for towing - more power/cooler EGT's to haul the heaviest loads.

Why is Water/Methanol injection so effective on Diesels?

Unlike gasoline engines, the power in a turbo diesel is largely a function of fuel. The problem with continually adding fuel is that you create an overfueling condition and reach a point where the exhaust gas temperatures become prohibitive (over 1500 degrees F). A 50/50 water/methanol mix will decrease EGT's approximately 200-300 degrees F while increasing power 70-100HP.

    Power is increased through:
  • Intake charge cooling - Water/methanol will lower air charge temps over 200 degrees F in this application.
  • Methanol - this acts as a combustion catalyst as well as a cooling agent.

Diesel Engines

What are the benefits of Water/Methanol injection?

  • Low cost - where else can you get up to 60HP for as low as $299? More power than other means of detonation control. Efficiency - leaner air fuel ratio can be utilized for normal operation.
  • Greatly increases air charge densities for huge horsepower increases.

Can the Boost Cooler be applied to naturally aspirated and nitrous engines?

  1. Naturally aspirated/high compression engines:
    In this application, water/methanol injection allows the use of pump fuel in all but the most extreme situations which effects tremendous cost savings as well as horsepower increases due to air density increase and realized timing potential. The system is activated by a boost referenced switch so that injection takes place only during high engine loads when needed.
    Engines using nitrous:
    With nitrous, water/methanol injection allows the use of full timing even with large (250HP+) quantities. Injection is controlled by the same means that controls nitrous injection.
  2. Naturally aspirated/stock compression: With naturally aspirated engines with less than 10:1 compression, water/methanol is used typically in warm climates to get the intake temps back to 60f. Benefits include: 10-15 HP increases from air density increases and full timing, Increased gas mileage, and carbon free combustion chambers. Activation is by a throttle switch adjusted for onset engine load. With this application, the nozzle is sized so that no more than 10% of total fuel consumption at peak flywheel HP is injected.
