If I understand your question correctly, you are suggesting routing cool air from the A/C to the intercooler, right?
I have to believe that you would get more power by simply not having the A/C compressor turned on than you would get by cooling the intake charge with the compressor putting drag on the engine.

It would be even better to remove the A/C belt.

No but he wants to keep the A/C and have an option where he can switch the direction of air. If its cool out he can have the A/C cool the intercooler, if its warm, forget the intrercooler and have it cool the cabin. Is that what you mean? It sure seems like an interestnig idea, but as these guys already said, simply leaving the A/C off would result in more power than using it to cool the intercooler. At least I'm pretty sure it would

Eventhough you lose more power by having it on, you could leave it on for say 20 minutes before a race to ensure it isn't heat soaked and what not. Then you could turn it off and kick ***.

I think it would be eaiser to rig up a welded pipe that goes through the IC that circulates liquid c02. You could have a small tank and an electric pump in the trunk. This would cool the IC and save the engine drag. Of course this would require a custom IC and it would probably be eaiser to just get a front mount. I am current ly looking in to an electric fan that i can attach to the top of the IC that will run off of a temp switch. I have friend who has Celica gts that has a topmount and he has done it it helps quite a bit and still allows good airflow to the intercooler when its not running. The hard part is that his IC is square and ours is rectangular.

There are many commercially available Co2 and NO spray kits for intercoolers, which would deliver exactly what you are describing. Routing your A/C coolant through the intercooler would most likely boil your coolant, and all the extra tubing you'd have to add would probably play havoc with the pressure levels.

I have heard things like the N-tercooler product can crack your intercooler.

The n-tercooler is a co2 based product i believe that sprays the co2 gases directly onto the tmic surface. If what i've heard is true then rapid cooling of the i/c is not good and will damage the unit given enough time.

Perhaps i could interest you in a safer alternative like water spray?

According to nitros express it can use either co2 or NOS *shrugs*

This is a little off-topic, but whatever happened to "Speedmonkee" and his turbo heatshield chimney part? I can't find his web site, and I'm curious to find out if anyone installed that part and what affect it had on heat soak...

EDIT: strange, now the site is back again; it was MIA when I looked a few weeks ago. His last news update is 02/04...

Ford have come out with a similar technology for use on the next Lightening pick up truck. It uses the AC compressor to provide a really cool charge for the supercharger. Has the effect of providing a temporary boost in HP. Needs some time to recharge between use though

removing all a/c equipment in our cars would result in more power and less weight. Thats more than 50lbs off the front of the car and removing the a/c condensor will allow more direct air flow to the radiator.
and i have never heard of a n2o or co2 messing up an intercooler, maybe a radiator.
