Highest boost pressure engine can safely handle?

Postby Barnsey8008 » Sat Jul 23, 2016 7:48 am

Saw a video on a guy running 20 psi and his city getting off the clock. Obviously that's pretty extreme but what have other people set there's to and still felt safe about not blowing the engine up?

i think around 16 psi the fuel cut, cuts in

23psi ive heard of, but it destroys the turbo (not the engine as its crazy low compression rate).

if you upgrade with a fuel cut defender and a new turbo, you could prolly do 18-20, esp if you use a 2 stage and use 15 daily and click to 20 for special moments (or even a little more).

the race cars had 23psi.
