That's a horrible idea, the SCer is not a heat exchanger so the cooling of the air would be minimal. But worse yet the bearings, bearing oil, impelers, gaskets, etc... would be subject to extreme swings in temp. Thermal expansion/contraction could be catastrophic for parts whirling at high rpms and tight tolerances. Plus cold metal is more brittle. Need I go on?I was playing with a couple of ideas with a buddy of mine who owns a Neon SRT and the idea of thermo wrapping the outside of the supercharger and hooking up a co2 to spray under the wrap. As far as how to manage the bursts of co2 or how much cooling the outside of the charger would do, I dont know. Just an Idea. It would probrably look ugly as shit as well.
