Oh screw it, after all is said and done its a Chevy, sharing parts with a C1500.

A stock C6Z dynoed 443 hp at the rear wheels - which, depending on the correction factor you use, is equal to or higher by ~16 hp than the factory claim.
I can tell you that the guy doing the dynos said that the "stock" numbers should be higher - said the car was pretty hot, and given a cool down he expects higher numbers.
I personally believe the C6Z is making more than 505 hp in stock form. I think American manufacturers want to be able to claim great performance numbers without claiming the higher power the car really has. Ford has done this with the '03 Mustang Cobra and Ford GT, and now GM is doing it too.

Although i think the C6 ZO6 is a beast, i dont trust every dyno i see.
I heard also in stock form it hit 440rwhp. Sounds ok but prob alittle too optimistic.
They added headers, removed intake and ecu adjustment the high numbers. Prob put some race gas in there too, who knows...

the car has LG long tubes with cats, NO intake (removed), changed all fluids to redline synthetic and NO ECU mods (ls7 edit isn't available yet).
When the car was stock, it laid down ~443 whp and 411rwtq HOT...after the headers and intake removal and oil it did ~492rwhp and ~472rwtq cold.

I can produce a very optimistic dyno sheet of my car if i wanted to. Im just saying dyno's can very well be decieving.
Im sure its a beast though, not doubting that at all.

I was about to say, that's insane power put down for a stock C6 Z06

< 500 miles from what I understand -
It's Andi's car (he placed top 3 in the OneLap in his Supra). LSx engines definitely "open up" a good bit after ~2500 miles.
FYI - some folks who know GM powertrain engineers were suggesting that the car - based on engine vs. chassis dynos probably has a loss factor very close to 12.5% meaning the ~440rwhp is just about right on the money given the 505HP factory rating.
The HP, BTW, uses the new SAE methodology which is supposed to be very accurate - you may have noticed the Viper Hp/Tq ratings both went up as a result of the new system (though everyone pretty much knows the SRT's were underrated).
The power from the headers doesn't surprise me too much - reminds me of the early GTS's that picked up a ton from just headers. LG was saying that the OEM header/manifold design uses cats that are very close the outlet pipes so they light off quickly (for low startup emissions), but that creates pretty bad flow/scavenging.
Definitely sounds like this is a 500rwhp car with LT's, intake and some decent tuning. I still bailed on a couple of opportunities to buy one though (neither at MSRP, though one was +pretty+ close).

You know Andi? Smart kid.
He built me a nice brake bias setup (Wilwood proportioning valve, -AN fittings, etc) for my Supra. I was always pretty impressed with how well he did in the OneLap given his whole effort was homegrown and financed OOP (and not deep pockets like some of the racers).
The Z interests me from a purely engineering/performance perspective (hmm, nice alliteration) - it's like the previous model (only much more so).
The engineering team does an outstanding job, then the design team does an "ok" job, then the car gets pushed through the GM machine and it gets cheapened up by the financial folks (final details like materials, paint, final assembly/fitment), and on the backside is handled by GM service (ugh). So where the running gear might be a A, when you factor in everything else, the car sort of averages out to a C+
I'll keep my plans for a 996/TT for now
