| Because just running the same boost wouldnt have made any sense? Might as well throw that comparison out the window, I dont know what the limitations of that turbo are, but at 40psi im sure its got to be pretty damn close to blowing 'hot air' considering they're making only 630whp @ 40psi I know what my IAT's are, and they arent bad at all.....its all about where you're at in the turbo's efficiency range. Either way....thats a bad comparison
