how much psi???

[TurboDreamz]

i run mine open boost about 20 psi daily been like that for two years.. spikes 25 psi in 5th lol oh its a t25. it hates stock boost so i give it what it wants, no restrictions.

14psi is about the max for the t28 turbo to be pushing.

15 would be chill... i had mine at 15 forever with no problems

I have a GT2871R and I run it at 15psi all the time, I've run the car at constant 18psi before but the head doesn't flow that good at that PSI, I been on stock gaskets the whole time and I never had a problem, but I also have 550cc injectors and a good tune.
