ok, here is the deal on those intercooler sprayer kits. It is a gimmick. Yes that is correct, a gimmick. The one's that use nitrous will show gains of up to 50hp because your intake is ingesting a good bit of the nitrous. Don't believe me? Have you ever seen how much those things spray? The use of co2 makes the kits completely worthless, as your car will ingest the co2 and will cause it to stumble and lose hp. This is the case on 99% of installations. Buschur racing has done many tests with these systems and these are their findings. I'm not saying that the kits don't chill your intercooler, but you are not going to see any significant gains from that.
here is a quote from David Buschur:
"Problem with the ntercooler intercooler spayer is this. The car ends up ingesting the Nitrous Oxide from the spray bar into the engine and this is where the big HP gains are coming from. This is a proven fact. Dan at Mach V called us with his huge gains and was so happy with the same mod, he picked up 48 hp and 56 ft bls of torque with it. Now come on, it doesn't take a genius that you aren't going to gain that from spraying cold stuff on the front of your intercooler.
To further prove the fact we loaned our dyno to another company that make these intercooler sprayers. This company was using Co2 instead of nitrous to cool the intercooler. Everytime the Co2 was engaged the car would miss and backfire. This test was run on a turbo Honda and a turbo Supra. We couldn't figure out why the cars would only backfire when the intercoolers were sprayed with the Co2 and wouldn't do it when run without it. Finally we made some dividers from cardboard to try and keep the co2 from getting ingested in the engine through the airfilters. As soon as this was done the misfires could be eliminated almost completely. It was impossible to completely seal the air intakes the way we were trying to do it. The gains from the just the spray bars on the intercoolers were then ZERO.
The spray bars, quite frankly, don't work. The only gains you will find is if you happen to get some of the nitrous in the engine.
Don't believe me? Next one of you guys that dyno switch the car over from the nitrous for cooling to straight Co2 and see what happens."

As far as putting alcohol in your intercooler sprayer like somebody mentioned. It sounds like a good idea. I mean put some alcohol on your fingertip and feel you finger get cold from the evaporation, right? Well, the alcohol has a much lower latent heat than water- Meaning it cant take nearly as much heat per volume with it before it evaporates- Hence why it evaporated so quickly at room temperature BY JUST YOUR BODY HEAT!- now you see the water (especially in mist form sheening in a thin layer like the IC sprayer is designed to do) is able to more efficiently move heat away.
I recommend using windshield washer fluid because it contains a little bit of alcohol along with water. Or just throw in some distilled water and some cubes for some quick runs.
