You can NEVER have enough boost!

Seriously though, I don't think you'll be able to run more than 17psi on the street without seeing any knock (a WOT pull into 3rd gear). Especially if you have a stock intercooler, heads, and no alky.

I agree with Banning,judging by your sig I dont think you'll be seeing over 17-18psi on pumpgas without a more efficient turbo/intercooler combo.

Reminds me of the question, "How can I tell if I've over revved my engine?"

Answer: A localized pain in your right hip pocket and the realization that your motor will now fit loosely in a 5 gallon bucket.

Not making fun of your question, it just made me think of this.

I guess the only way to know is with a scan tool and looking for knock. No TR should be w/o a scan tool of some kind.
