Too much boost?

How much is too much boost? I have a 2002 ford powerstroke, and the only modifications i have to my turbo is a banks wicked wheel. My truck puts out 32lbs of boost is that too much for my stock turbo, will it last?

Rule of thumb is try to keep it under 30 on the stock turbo. Can you go over 30psi, yes...but it isn't going to last as long as it would normally, and the turbo is pretty inefficient above like 25-27psi. I used to hit about 31psi....but now I'm back down to 25-27psi....and it feels like it's missing something around there. Big Oil and injectors will fix that though.

im guessin your running a tuner? and exhaust? 32 is actualy prety high for an obs truck not a bad thing tho at around 38 psi you blow head gaskets and at those boost levels your stock turbo gets fried too. you wont see those numbers till you get big injectors

Yeah I'm running a 6 pos chip, 4in exhaust, zoodad mod, rapid flow intake, a banks trans command and soon water meth. injection. My truck is a f250 extended cab, long bed, what are some good quarter mile times for a truck like that with about the same amount of modifications? Rankroddin250 you're from lewiston? Thats awesome, I am currently going to school in Moscow, it is good to hear from someone in good old Idaho!

It's a 7.3L, not a sicko. Tuning plays a huge role.

Yeah i would back it off a little, down to 27 or so...32 your head gaskets should be ok...once you consistently get over 40 psi head studs would not be a bad idea.
