I've heard the ring lands go, after 250hp you are on borrowed time.
Paul is running 14 or 15 psi on a stock 99. It is still holding together. If your motor is running good. I would run it 14psi with a good tune and not worry about it. When it blows, Then build the next motor.
Buy rods and pistons over time. Then push 17-18psi.

Or are you wanting to track it?

Capitalize the first letter of each new sentence. Is English your fist language?

Paul's now running 17-18psi on that motor. I'm running 15psi on a gt2560r on a lower compression 94 engine. All good so far.

Yeap. I have a GT3271 and I'm wondering how much I can safely run on my 99' with a lot of headwork. I'm thinking 12 is gonna be it.

^ Why?

If the compression is good, then why screw with it?

Oh, and the word is "goes."
