At CMP the drivers of at least two cars were using windshield washer spray nozzles to cool tranny coolers etc so I'm thinking that wouldn't be that big of a deal. IIRC alcohol evaporates more quickly than water so if you spray that instead of water you get better intercooling and less evidence, er, liquid on the track.

Does anyone else think that this is the MOST STUPID idea that they've ever heard? Spraying a flammable liquid inside an engine bay, onto a hot surface?

Depending on how you vent the engine compartment it could work as a pretty cool afterburner!

could make for an interesting experience drafting him... "honestly officer I haven't been drinking, it must have been the alky cooling vapors"

Actually, since you'd want to completely seal the intercooler from engine heat anyway it wouldn't be as big a problem as it sounds. The afterburner effect would definitely keep other drivers at bay.

You have to realize the amount of air flow going into the motor is way way more than your factory AC puts out cold. IIRC you said it is a 2.7L and assuming you run a nice and tidy 5psi with poor efficiency your looking at 253CFM, now how many CFM you think the typical automotive AC unit can push... really... 10 cfm... 20cfm.. and now your not cooling ambient air... it is gonna be heated... bad idea, stick to reliability and handling, your gonna commit time and funds to a job that is not going to be in your best interests...

best argument so far. i'll do the math and let y'all know.
