yea they actually use CO2... see, its ogrinally made for nitrous+tubo applications. as the nitrous shoot thru the engine, it heats up (duh!) add in a turbo, and the heat is extra high. so they make a CO2 setup where you wire an oval like tube right in front of the intercooler. this ube has tiny holes in it. as you engage the N2O, the CO2 is set to flow at the same time. the CO2 travels thru its own piping and is blasted right onto the radiator. now you can use water of course but a CO2 app works better. and heres why, in case you didnt know... :gringreen haha, ok whos ready for a chemistry lesson?? :gringreen ok, well, CO2 is a gas, so its naturally (for the most part at least) go to be colder at room temp than H2O. now you can actually compress this gas. (dry ice is actually compress edCO2.) now as you compress the CO2 gas it drops it temperature. and now that its under pressure, you can bottle it, just like a CO2 tank on a paintball gun. now going back to the point, obviously shooting a very cold gas right onto you intercooler will lower your engine, oil, and turbo temps, and because the temps are lower, your car is going to run better! well, i hope somebody has learned a little bit from the post.... if not then, for the record, i DO indeed admit to how badly i sound like a total nerd. haha, thats all the chemistry lessons i have today!
haha!
