Hey guys,


I was wondering what kind of gains could be had by having an alcohol/water injection system on an EVO with the stock turbo? I know that the system itself does not add power but it allows you to run higher boost levels and at the same time deter knock. What kind of boost levels can the stock turbo support usually on race gas? 25 psi? If so, adding a system should be able to yeild an extra 40-50 horsepower, correct? Also, does adding an alcohol/water injection kit require a retune? Anyone?
