I asked some similar questions when I first started posting on here. The answers I got were that the improvements would be mostly wasted, since our intercooler sucks so bad. To be fair I don't think anyone has actually tried it... But the answer I got was that you could wrap all the exhaust, shield the intake, put on turbo blankets, and it wouldn't matter much. The air gets heated up by the compressor, and the intercooler just isn't up to the task. You'd see WAAAYYY better numbers by improving the intercooler. Then worry about the insulation. At least that's the gist of the answers I got when I asked. I would like to see someone try the combo of exhaust wraps, turbo blankets, and hot pipe insulating/shielding. For science, lol.
