^ Actually man, Meth/water injection is used to raise the octanage of the air/fuel mix so it doesnt pre-ignite in the cylinder. Its like runing race fuel... its not to cool the intake charge..

Oh ok, so does a higher octane mean cooler intake charge? I was under the impression timing was adjusted for colder air that would allow more fuel. But still I think the end result could be the same, more power without having to adjust timing and not having to worry about hurting the engine.

not sure if intake charge temps is the same as Intake Air Temps but when i was spraying meth/water in my supercharged cobalt. My IAT2 dropped ALOT by using meth/water injection. I was seeing 18* timing with 140* IAT2 temps, when i put meth/water on i was able to raise the timing to 22* and IAT2 dropped to 130~. Then once i got the TVS Supercharger and took the M62 off and also changed my mix to 75/25 (meth/water) put a bigger nozzle on (7gph). I raised my timing to 25* (max timing the LSJ Ecotech can produce power) and only seen 130~ after 4 runs on the 1/4. So in other words, it does both raise octane level and cool IAT's

Ive heard of turbo guys using the water/meth to help keep intake temps down and not even advance timing. It was a way of helping the stock IC not get as heat soaked and lose power. They would just let the ECU do it and this way if they ran out of the mix they wouldnt have to worry about the timing being off as the ECU would adjust it again. Kinda like a different type of IC system that they could get some bennifits out of everyday driving and then tune it for track time quickly and then back again.
