1) Cars now use R134-a, not R22 or R12 anymore.

2) It's not a new idea to use the A/C system to supplement cooling. Having an independent A/C system just for the intercooler is going to be awfully heavy, but people have definitely sacrificed their cabin A/C to cool their intercoolers.

That said, at full-bore, an A/C compressor consumes a lot of power. Most cars, at WOT, shut off the compressor (in slow cars, you can feel the air begin to blow warm on long WOT pulls).

Is it worth the trouble? It'll keep heatsoak at bay, but it would provide for a very inconsistent operating temperature (especially if the compressor shuts down at WOT).

I'd consider a well designed AWIC before I invested too heavily into something like this. After all, I'd rather my A/C keep my cabin cool.
