[immortality]

i've heard a 50/50 mix off water & alcohol works real good, water cools the intake charge and steam cleans the engine (hehehe) the alcohol has the same effect of increasing the octane rating of the intake charge. the combination alcohol/water injection i've sen a few time on turbo cars. one chap i talked to suggested that injecting the mixture directly onto the impeller is the best way to atomise the mixture. this was based on a centrifugal supercharger setup however
