It reduces the air inlet temperatures (in all applications) and also raises the resistance to detonation and pre-ignition because alcohol has a much higher octane rating than gasoline from the pump. These allows the user to run higher static compression ratios, increased timing, and so on. While gains from meth injection in an N/A application are not huge, they are certainly measurable.To further a comment by quickstang about ice bags on the intake...Here in Phoenix, we have pretty crappy air. My old combo would run typically in 13.0s at 110mph pretty consistently with no real effort involved. However, when I would ice the intake down for 30 minutes before a run, it would net me a guaranteed tenth and 1 mph. Chemical intercooling is not much different. All combustion engines can benefit from a colder air inlet temperature, (within reason) supercharged or otherwise. Obviously, the gains are more significant in non-intercooled forced induction applications where the air inlet temperatures are very high.Paul.</blockquote>
