it'll make so much more power when you cool the intake charge like that. I actually took a Stillen intercooler, put it 1/2 way into LN2, and used a heat gun to blow hot air through it. The inlet side reached about 600F, while the outlet side stayed a cool 10-20F for almost 15 minutes. I got to thinking of a way to actually DO this on my car (think liquid:air IC instead of air:air), but other things took priority. Maybe will revisit someday...
