I have been pondering the idea of installing an intercooler somewhere in the intake line, and then cooling it with a spray of liquid CO2: <a href="http://s1.promotionsupplies.com/ebay/just-intercoolers/images/intercooler/au-ic0045-30-1.jpg">http://s1.promotionsupplies.com/ebay/just-intercoolers/images/intercooler/au-ic0045-30-1.jpg</a> I will need to find one that will admit enough flow, or install two, since most of these things are made for imports and are only ported to 3 (<600 CFM).
