My friend and I came up with this idea a while ago and never really decided to go through with it. Apparently we weren't the only ones, as it has now hit semi-main stream. Anyway, the idea is to spray CO2 onto an intercooler, to reduce the air temperature. Has anyone done this with their TT??? If so, please elaborate on how it turned out/if it was worth it. If you don't get the idea, check it out here:

Ironic side note: my friend drives an SRT-4...he shart himself when we found the above website!

 

A properly sized intercooler will cool the charge down to almost ambient. Add water/meth injection to the party and your below ambient and what the co2 can lower it to along with all the other benifiets of w/m injection.
