I live in the Phoenix valley where the temps are ridiculously high in the summer. Don't tell me you're from Miami, highest average daily temps in the nation blah blah, fact of the matter is it does not reach the extreme temps that we see here in the desert, chart for those who don't know what hot is: Right, that means 30% of the year we are hotter than the hottest day of the year for most of you. I understand that many don't deal with these temperature extremes, and the importance of this kind of modification isn't very high. But for those who do experience heat soak or have to combat high ambient temps, I'd like to know if anyone has gone this route on our cars and which they decided to spray. I've read if you're running E85, or spraying nitrous or meth, the effects of an external applicator are partially nullified. I've ordered the 'Big' AD-E FMIC in hopes that the sheer mass of the unit will help this issue, but I know its hard to exchange heat when 120* air is passing through the intercooler fins. I suppose I'm curious if there is much benefit to running something like this in my situation and which is better to spray, C02 or N20?
