I was spraying before the throttle body and my IAT's stayed the same. Granted, I wasn't putting much through the supercharger. It seems the intercooler does a great job of heating the air after the spray cools it. Now I spray into the Y pipe. On short pulls it keeps the IAT's in check. After backing off the IAT's will drop like a rock from the residual effect then bounce back up almost as quick. On long pulls or while racing it helps keep timing from being pulled for much longer. I'm spraying 5 gpm at 15 PSI. The octane gained is really very little. With a huge nozzle the water meth is only about 4% of the fuel being consumed so that 116 octane meth is a small portion of the fuel ingested.
