Didn't use any Delta T, just assumed 100% efficiency of transfer (which we know isn't the case, making the system even less effective than I predicted).

Keep in mind too fellows that even operating at 100% efficiency it takes almost 6 hp to operate a system with the cooling capacity of our AC system.

Another thought for on-demand cooling would be a liquid CO2 tank with a remoted valve. The weight may offset the benefit but if you blow some CO2 out of the tank it will cool rapidly in the direction of -40 C (or F, doesn't matter). Same Joule-Thomsom coefficient at work as in an A/C compressor. CO2 is also cheap in bulk. Of course you wouldn't want CO2 sucked into your intake but it would make a bitchin' heat exchanger medium and in a pinch you could use it as a fire extinguisher...

LOL, I like that.
Some sand drag cars use that exact idea, they're only going 100 yards though (sub 3 seconds )

A guy named Jim Griffin has already made a cooled/refrigerated air-water intercooler for a MR2 Turbo.

I'm not sure how his system compares to what you guys had in mind. I've seen it in person and have talked to Jim before about it and he seems very happy w/ it. And I'm sure he'd be happy to help you guys out.
