just stay below 400whp and you'll be ok. I see more and more running 400 - 450 with stock but there is low margin for error and you better have it tuned. either way it must be tuned what ever power you're adding. I'm not to worried about a SC since your power is linear compare to a ST or TT that get that sudden power once you hit boost... good luck.

I'd try to stay under 9psi; unless you want stuff to start failing so that you can replace 'em.

It depends on your tune and your surrounding mods. I thicker metal head gasket will help to lower the already ridiculously high compression. A methonal injection kit will also help you run a little bit more boost (this is not recommended as the injection pump could get clogged, fail, or run out of methonal and lean the motor out). The bottom line is that with Greddy's stock boost the G is a fast car, the power comes on hard and will put you in the back of your seat at 5.5 psi. That will usually get you about 350 to 365 at the wheels. Once you hit 8 to 9 you are on the edge of the limits with the stock rods (which do not like boost from day one). You have to keep in mind the effective compression ratio under those types of boost conditions are close to 16:1. It is hard on those weak little rods. If you are going for huge power you really are maxed at about 8.5 or 9 with an AMAZING tune and good luck. If you want to have one hell of a driving experience that is FAR less likely to cause serious problems over the life of your car, then 5.5 psi is a good safe number that will definately generate some serious power.

It's all about the water injection, baby. Stay tuned for my own offering in this department pretty soon.

now I'm confuse so a TT that is running let say 5.5 Boost with 360whp is less stressful than a ST who's running at 8 with 360whp?

I'd venture that the TT setup would be more stressful because it likely has more peak torque.

It depends on what kind of driver you are. If you put the car in gear and then hit it in a TT it isn't as bad as if you are dropping gears left and right and scratching gears here and thre and running to redline everywhere you go. The biggest fear in a TT (which I haven't heard of a problem to my knowledge) are the rear diff. and rear axles. You should already be running aftermarket clutch and flywheel so the problem won't be there (unless it's stock). The turbo on the ST setup will have to work harder to create the same power and 8 psi is less stress on the motor than 5.5 psi but if you drive like a sane human being the torque SHOULDN'T and I repeat SHOULDN'T break anything. But I hit 366 rwhp and 348 tq at 5.5 psi.
