Cranking up the boost on a T4 mk1

I also found out the standard boost pressure on a t4 is 13psi, and taking that each turn rases the boost pressure by 0.75 psi (for arguments sake), I am looking at a max pressure of 15.6 psi. Or am I increasing this wrong, and is it just the baseline pressure increased? Barney

So assuming that is the case, I should be running just over standard basline pressure, and it should'nt be creating any terminal stress to the engine?

hi, ive done this to saab 9000's and T5's without making them go bang. the car is equiped with an overboost protection system, so dont loose any sleep. all i would say is dont stamp on the gas too hard at low revs cos high boost at low revs is where possible con rod damage can occur, running hard at high revs wont be a prob. as has been mentioned, safest way is to find out off the forum what is a safe boost level to run, fit an MBC and boost gauge and stay below the safe boost limit. wayne

i run mine at 14 - 15 psi and it flyes it got a kn induction kit s/s exhaust and a mbc bypassing the bcs and a dump valve it sound really good and goes well to
