"Think about what a turbo does. It forces the engines exhaust gases, (which are very hot, hotter than any air charge could ever get ) and force feeds the exhaust gases into the engine.
Having a cold or hot air charge makes no difference when your pumping 1000 degree exhaust gases into the intercooler and than into the engine."
Yeah, from a technical standpoint, your inlet temps aren't going to make a difference when you're pumping exhaust into your engine..
