Boost ??
I have a 2005 GTO with an STS kit installed. It has a GT67 turbo with the STS intercooler and it also has a Devil's Own Meth kit as well. So far that car has shown just a hair over 500rwhp(with a poor tune). It made 7lbs on the dyno, and shows 9lbs on the street.
The car now has a 2 bar SD tune and runs seemingly safe on the street (A/F 11.5-10.9). What I want to do, is turn the boost up to about 11lbs. I just don't know if the motor will live okay. Anybody have any experience boosting an LS2?
Thanks in advance
Tony

from what I understand LS2's are better at handling boost than the ls1 and there are several guys pushing over 11psi on a stock block ls1. I think youll be fine with a good tune and you should put down some good numbers.

Thanks for the reply. Any others have any experience/opinions? I am really wanting to try this, but fear wrecking my engine. I may let this pass for a while until I have $$$ to fix it if it turns out like this one:

The tune has been great. I was just looking for opinions. I didn't want to push my stock motor over the edge. I have a 12 gph meth nozzle in it now, and will upgrade to a 14 if I do up the boost, as well as rework the tune.
Thanks,
Tony

I have Motoron 60lb injectors, and a 255lph intank pump. I have enough duty cycle left in the injectors to increase the boost, so fuel shouldn't be a problem.
I do keep the meth topped off all the time, but it really doesn't go through too much.
