That's what I'm reading. Spoke on this topic with the builder from TrueStreet Performance last year & I believe thats what he said 6psi on street use is just fine. He also said aggressive cams don't work well with forced induction. What do you guys think? I need that oldschool popcorn exhaustI think 6psi is safe with the stock 6.4
Damn!I wouldn’t even call it “safe”
Cause it’s known to kill 6.4’s prematurely
in general
Yeah there is no dragstrips in NYC & I ain't no drag racer so won't be competively racing on a strip or anything. I'm just a blvd cruiser doing normal driving and open it up in backroads once in a whileWell it’s a high compression engine so if u add boost and don’t race it should be “safe” as in normal driving you shouldn’t be going into boost much
if ur racing constantly “dragracing” it will wear out everythingin due time
