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
