Congrats on the times..Any video from the night..? When do you plan on going back out on the 18psi. I bet you will see a good improvement with the addition of some race fuel...

We put 17psi on the stock LQ4 bottom end a couple weeks ago. Went 122 in the 1/8th but theres still alot left in it. Based on some online calc's we should be a little over 900hp at the crank.

we keep it under 10psi on pump gas for a cam only 5.3 with intercooler. at that level it is still mid 10's or faster in the fairmont. 12psi seems pretty agresive but that is based on experience with trucks where the load is higher and the run is longer.

O ok cool, I just thought I saw somewhere where you posted another specific turbo number. Sometimes numbers on them dont exactly mean the exact mm.

Also what exactly is a gm power center?

on the fender of a chevy pickup there is a little red box that the power from the battery comes to then from there goes else where I used the same thing in my car just for a more factory kinda feel.
