I was looking at my friend Summit Racing Import catalog and it has some Cryogenic CO2 nitrous looking system...I was reading at it says it can spray CO2 into the fuel line and make the fuel really cold like -80 or something like that, or it can spray it into your intake and make a cold air charge...now would this be worth it? I mean what kind of gains can you expect and how good is it for the engine? I know colder denser fuel makes more HP, that why people add cool cans....AARON

Without a poweradder ther is no need for it. It is primarily used to keep detonation at bay. It's along the same lines as the propane and alky kits on the market. It may give you a slight bump in power(ability to turn up timing a bit more), but IMHO it's not worth the cost on your current setup.

NX has a system like that for intecooler called the N-tercooler or something like that.
