That was only with a few hundred miles on the car though. Now with a few thousand miles it feels much more powerful so I'd imagine numbers increased as the engine broke in completely.

So here is one for the books! As you know i put the stock cat-back back on it, well i first dynoed it SINCE then today. The car belted out a max of 501.8HP and 460.7TQ today, and backed it up with a 499.6 and 457.0 immediately after! The highest tq was on the 1st pull at 466 ft/lbs! So it didnt loose power, it gained a few and gained a max of 15 ft/lbs and avg of 10 ft/lbs with the STOCK cat-back back on the car! Dyno sheets will get posted tomorrow and there was even video taken of the 499 pull and a celebration burnout vid where you can see the stock garbage cans for mufflers for any doubters hahah
2nd, thats pretty sad/weird that your 1 5/8 ebay headers&stock catback seems more powerful than your JBA catback!! and looks to be as good as the big $$$ headers!!!

Most 500RWHP LS3 Vette guys bump up the compression or have some head work along with some LG/Kooks/ARH LongTubes and possibly a ported intake. Lets not mention the fact that Corvettes have a less parasitic drivetrain due to a Trans Axle design
Im gonna say something is up with your dyno. Take it to a DynoJet and you might see what some are talking about.
The main thing is your happy tho!!

i have seen a 500rwhp vette with just headers, x pipe, vararam, cam and tuning

What compression Ratio??
Did you know Trans Axle's are less parasitic also??
Do you have an SAE corrected dyno graph?
What Long Tubes??
What Octane for the tune??
The list goes on forever. Point being 500RWHP N/A with less than 400ci, No Head work, Stock Compression Ratio, STOCK Internals, 91-93 octane, on a dyno jet is a VERY hard task to accomplish!! Let alone using 1 5/8 Stock size primary Flea BAY Long Tubes.
But as long as the owner is happy so be it. Myself, I would be a bit leary on the Dyno Numbers as others have stated.

in some majic intake that kills a GM intake...they don't and never really do.
It's hard to find people post that they went a faster ET with a FAST. I still love how TPIS proved that the LS6 intake is very good when they modded an LS6 intakes opening to 90mm. It out did the FAST and it only cost $350 when you send in your intake to them. And still LS6 intakes never split open and the FAST didn't even have a proper mounting system for the MAP. Thats a joke for the price they charged. I'll take my chances with my LS6 intake no matter what mods i do. If i ever go as big as a 427 i'd still use an LS7 intake, but never any FAST intakes. Just my opinion, to each is own. Let the FAST lovers scream away..LOL

but oddly with the same cam, but in a smaller ls3, not ls7 he is only making 40 less rwhp....
yeah they are called c6 z06's
these numbers are not real, the dyno correction factor is cranked up, you can see that clearly by the tq number, the motor simply does not have the enough dynamic compression with that cam and stock static compression ....
the OP can believe what he want or stay in denial of the truth... until you post up some quarter mile speeds to back his Hp this will go down as a BS dyno number

Calibration means a lot on Dyno's, as far as Mustangs reading low compared to Dynojet numbers, that's not always true. It's all in how the dyno is setup & how the correction factors are setup. It's nice knowing dyno numbers, but in the end a Dyno is just a tool used for tuning. A way to get a load on the engine to be able to datalog to be able to tune. My tuner has a dynojet that is notorious for putting out very conservative to low numbers compared to other dyno's in my area, but he doesn't tune for HP numbers, he tunes for track times. When we first tuned my car when it was just CAI, CAM, Muffler delete, it was only making 404 RWHP, lots of others claimed to make that power with just a CAI & Small cam, my cam is a pretty damn big.
I'm not sure if this is the same video I have in my signature, but listen to this,http://www.youtube.com/watch?v=ZEetM7I-vv8 it this is through mufflers but they are only bullets, I'm adding maganflow's shortly, I already have a set of oval Qtec's, just have to install them to bypass the maganflows for the track. My heads have been ported & milled since this video, but I did the retune on the street, so I don't know how much it added, probably another 20 or so RWHP.
I'm hoping to have gears & lightweight & shorter bogarts on it within the next few month's & I'll be shooting for 9's with the stock short block.
