But the hard part is keeping it a closed system so that you don't need to have an extra tank (CO2, Nitrous, meth) but efficient enough to make it worth the cost.

I've read of some systems tapping in to the A/C system to cool the air but the added load on the compressor off sets any gains that could be made.
