got my greddy profec b spec II in. so im wondering how much boost i can increase too on a stock japanese motor with full 3in exhaust, intake, FCD, FPR @ 65psi.

i was kinda hoping to hit 1 bar but right now im only running 0.5

can my stock S5 turbo take that much?

 

id keep it below 12psi.. what IC are you running? if stock, 12psi max.. if front mount maybe a bit more, but the turbo doesnt like the higher psi much, and will see a shorter life

 

Don't go over 12 psi on the stock unit, it really can't do much more than that without leading to trouble.

 

so will that be fine on my stock injectors? with a high flow fuel pump?

yep im on the stock intercooler

 

up

 

with a upgraded pump 12 is fine, dont go higher..

 

You are saying that 12 PSI is fine without upgraded injectors and just a big fuel pump? Can anyone else confirm this?
