Hey guys just wondering what the max boost i can make with a hybrid S5 turbo? and if so what specs on the turbo would i need to achieve this. I'm looking to build a stock setup and to make as much power with this setup as possible, i have a front mount ready to go but i was thinking designing a top mount so that the boost would come on very quick, i know that everybody says front mount is the best but i would like to try to see how much power i can make with a upgraded tmic. I find that ARC wants way too much for there intercooler, so maybe i can make my own. Anyways really curious about the S5 hybrid question.
