Alcohol/water injection is a method for cooling the combustion chambers of engines by adding methanol/water mix to the incoming air-fuel mixture. This allows for greater compression ratios and largely eliminating the problem of engine knocking due to detonation. Many alcohol-water injection systems use a mixture of water and alcohol (usually 50/50), partly because the alcohol is combustible and will raise the octane level of the fuel. While water is not combustible, it has a greater capacity to cool the intake air temps down more than methanol alone. This effectively increases the octane rating of the fuel allowing performance gains to be obtained when used in conjunction with a supercharger or turbocharger, altered spark ignition timing, and increased boost levels.
thanks for posting, I didnt get around to do so... a little lazy.
