Ok according to sts at 5psi it will give 414rwhp, is this likley what ill get...
what will the power difference be between a 02 trans am ram air and the a 02 firehawk, will the firehawk put out more hp? what numbers do people see with a bone stock motor with sts kit(5psi) and some bolt-ons(pulleys,ported tb, gears) assuming you have a good tune and upgraded turbo, on GOOD TUNE will the motor handle 7psi, im thinking thats the tops ill run on stock motor...say I have a 02 firehawk m6 bone stock with sts 7psi and 3.08 gears, would that make mid-high 11's on slicks, and low 12's on street tires all day long? anyone running 7psi on stock motor?

Well, i can answer for the pulleys, ported tb and gears... which we've discussed before... pulleys - anything that causes less parasitic drag on the engine will show an increase in horsepower/torque, period. Ported TB, people are saying it is not worth it in a forced induction setup, as it is not the restriction in the setup, and gears, like we have said, taller seems to be better for proper loading, don't go with 4.10's unless you're on 31" tall slicks LOL, go with 3.08's or 3.42's and a 2 step or transbrake, however your car is set up. I ran 7# on mine, and my tune was jacked up and the motor came apart cuz I had oil come through the top. You'll make more than 414rwhp on 7psi, I can guarantee you that, unless they jack the tune way the hell up or you have a major problem. Please use an intercooler, boost is addictive, do it right the first time, rather than re-doing it later. You can choose to use meth injection on top of that. If you can fire out of the hole, you can run 11's, I was running NA without anything fancy, not even a tune on et street radials 12.30's @ 112 with a 1.71 60', nothing real fancy, fast for a "street car", but boost is a whole different story.

My car was starving for fuel on the dyno and put down 426.16RWHP/ 432.6RWTQ (SAE numbers) at 5PSI. So, yes, this is a believable claim.

You were starving at 5# with stock injectors or the 42's?

With the 42#'s, 255gph pump, AND hotwire kit. That's why I'm making a return style system with a boost referenced regulator as we speak.

I read your post about that, not quite understanding, would like a better understanding of that topic... =\
