How are these numbers for stock motor, 6 psi? 453 hp at 6000 rpm, and still climbing pretty fast. Absolutely stock motor, with the exception of longtubes, with cats, and a loudmouth exhaust. It is a 99 wiht LS1 intake. How much would you think it would gain with a ported TB, and a LS6?
A/F was 11.8-12.0, timing at 5500+ was about 18 degrees

It was a customers car, so hopefully I can convince him to do all the little things that add up.
I wonder if a LS6 wil make much difference on a boost car, because its not like we're relying on an inerial charge to fill the cylinder anymore. Wil outright more volume help?
This was an ATI 'charger. I hate Vortechs

I can't imagine anyone would be disappointed with those numbers on a totally stock engine. My powerdyne only made 390 on a stock engine for reference. I'd spend the money on a cam before an intake, too, IMHO.

Good numbers for stock motor and headers.
I think most 6PSI inter/after-cooled kits give between 420-430RWHP (100 extra ponies).
The headers probably helped a ton.
BTW, I see you hate Vortechs. But where are all the 10-second ProCharged 346ci LS1's in Maryland?

Jeff, that is pretty good...hopefully we can see 460+ on my car.
I started the install this weekend, and got held up on a few pieces. ATI is sending them ASAP, so i'm looking at being finished next weekend.
