been tryin to search for this and havent found anything anyway I was wonderin what kinda numbers do stock bottom end ls1's with stock ls6 heads, stock cam,lt headers, offroad x pipe and borla straight pipe catback make. I'm gonna buy this kit pretty soon and I'm hoping for around 510rwhp is this pretty reasonable?

Check out the C5's in the project car and customer car section of my website. Depending on what dyno you are on, over 500 rwhp can indeed be achieved. Bob

From what I have read 510 should be attainable with that setup.

I have the A&A kit laying in my garage ready for install. From what I have read and talked to Andy, mine should be right at 500rwhp with LS6 cam, the kit and good tuning. He said to expect a good gain when adding the LT's, but I didn't ask exactly how much to expect. I would guess around another 25.

So you should have no trouble doing it with LT's, LS6 heads.

Quite a few people run 550 rwhp on a stock bottom end with a GREAT tune.
It is pushing the limits of the stock bottom end though.

510 RWHP can be had easily with the P1SC.

I have a 98 with the stock C5 heads and cam. I have LT headers and Borla Stingers with an A&A P1SC. It put down over 490 (522 before correction) on a very conservative tune. I am running 18 degrees of timing with an A/F ratio of 11.8 on pump gas. It could have easily put down around 525 with a more aggressive tune on a higher octane fuel. Once it gets around 500 it's all pretty much feels the same. I would guess the car should make right around 500. If you really want 500+, just tell the tuner. He should be able to get you there no matter what.

510rwhp is dooable, but you are going to have to limit your boost to 6psi. with the stock bottom end.

Mine made 501RWHP with a completely stock bottom end, manifolds cats, Z06 catback. I had around 20,000 miles when I pulled it and sold it. Never had an issue with it. Oh and 501RWHP was at 10lbs. I normally ran mine at 8-10 and i drive my cars. I fyou get a good tune 8-10lbs is safe by all means. And min was a mail tune for 18,000 miles.

I sold it because I traded my 2000 C5 for a 2006 C6

PS: My sig is before i got it retuned. I am in Iraq now so updateing my sig is not much of a priority

BadMonkey, I have saw your car at Clay City before, I was there the weekend the rear let go. The people on KYHP said the car was an animal.

Yea it was, it was too bad the rear went on that pass too because it hooked lol. Would have given me a good time that is for sure. Just you wait though, the C6 is getting something as well from a vendor on here. It will be at the Carl Casper car show later this year in Louisville while I am over here in Iraq Just look for a yellow C6 at the show.

it's a tough call.
i don't think it's reasonable with a STOCK cam - you really need a blower cam and the tune is EVERYTHING
we had a guy here in AZ that had a new blower cam put in his '03 and with the new tune, he picked up over 100 RWHP (put him at 575) can't recall where he was before that - but i'm thinking in the 450 RWHP area - perhaps even 425!
