Just wonderin what a good heat exchanger would be for my setup?:shrug: I'm thinkin since my theme seems to be "overkill" with my 15gpm pump, spearco 2-170 i/c core(4.5"x9"x10.125"), and ~2 gallon resevior, that I will go with a 24"x7"x3" heat exchanger made for the lightnings and cobras just to keep it goin.:lol: Whatta you guys think? Recon it will give it away that I'm turbo'd with a big arse shiny heat exchanger out front? I want to keep it as "sleeper" as possible. :waytogo:
