Max psi on a stock 2003 g35 engine
This might already have been asked a dozen time, but i cannot find the thread so.
How much boost will a stock g35 engine take and without any other mods (heads, exhaust) could you expect to make before the pistons shot through the hood??

Go to the Forced Induction section here or My350Z.com
But I think this video will do.

10 PSI should be a bit safer.

you do realize that psi does not mean, or often correlate with power.
i'm running 15psi on my setup and way less HP than say a Greddy TT with 15 psi, like hundreds of HP less.

The highest I would go is 10 PSI, with a good tune.

8psi with a good tune.
But I'll agree with "too general of a question"... while it may seem straight forward...
Here's some examples... a supercharged 5AT car may only make 320whp @ 8psi
A twin turbo 6MT car may make 450whp @8psi
I would say start off with HP, and go from there. Around 400whp is when you MAY start to see problems... which is NORMALLY between 8-10psi.

Well it took alot!!! I can't wait to go fuction:TUNED so they can work on my G!!
The lower the psi the better for your engine. Based on what I have seen the motor is at more risk running a higher PSI with the same power. Do not compare SC and Turbo since SC can run higher PSI since it only give you the power in increment all the way to redline, so basically your motor only see that Peak PSI if you shift all the time at redline. I'll pick a 5psi 400whp turbo over a 9psi 400whp turbo
Now to answer the question, on the safe side, I will stay below 9psi on stock motor with a Turbo.

It was a total stock block and dave at functiontuned just took it to its limit.Dave allready had another engine to put in it and would you believe that the stock block at 18psi and lower had over 150 pulls on the dyno.........and it still held up pretty damn good.
