Psi rating on stock motor

[fasternu_674]

Is it safe to run 11 psi from twin turbo's on a 5 speed V6 with 75000 miles on it? Thanks

yeah...........if you got a good tune. might not last as long, especially if it sees full boost every time you take off

[fasternu_674]

What do you recommend for psi then? Lets say with a good dyno tune.

maybe... ive heard 9 is the safe bet though for a stock engine v6.

Good answer !! Run a safe tune

[sledgehammer]

you could just run under what is safe by a little bit to be extra safe and get some engine work done. then go for big boost +11!!!

I run 10.6psi on mine, stock motor and I used to drive it everyday to work until gas prices started creeping up again.

yeah.. i agree... why not do some engine work first, then get the turbo.. might be more worthwhile and a better investment.
