I wonder about all this stuff sometimes..... I need to get over to my buddies shop and take a look at his M4 GT4 race cars and see what they run in different places. I am sure they got regulations on what they are allowed to bolt on and run in the WRL & Trans Am series but I don't remember seeing any couple grand intercoolers under them hoods and I would think they operate in the most extreme conditions. Now of course they probably are not making over 450 hp or so but.......
Still makes me wonder sometimes
