What is the stock psi setting on the STI and how high can you go?

Someone tells me that some guy is running 30psi on STI. Is that even possible? I don't buy it at all but I just want proof first from you guys.

 

14.5 psi is stock on STi
13.5 psi on WRX

You need to be a little more specific with your question. If you mean what is the max boost a perfectly tuned stock STi motor can handle, no one knows yet. My guess is 20 psi.

Anything is possible, just require money.

How much boost you can run depends strictly on how deep your pocket is and how long you want your engine to last. There are engine that run on 60 psi that cost $100K, that would last 30 minutes of running time.

To answer your question, no, I don't think a stock STi motor can handle 30 psi.
