To get a supercharger that flows more volume and more air to make more power I've read on here ours get out of efficiently around 22psi and run hot ....putting a bigger pro charger would solve that problem and going with there inter cooler it might push past the 450whp mark lol just thinking didn't say I was going to do it ...just thinking of ways to make more power of course u would have to do all the fuel upgrades to handle the power and a dyno tune
