there's an easier way. i saw a device set up in a magazine. it used freon to cool the air before it entered the chamber as well as cooling the intakes. especially useful for turbo cars. but i forget what it was called. it was relatively cheap as well.

besides the a/c is a drag on the engine so i don't think it would be a good idea. taking energy to make energy. i'd remove the a/c if i wasn't leasing this thing any way.
