The generic design goals? Or one random sampling of a customer owned C6??

design goals or advertized ratings - here's what i'm driving at - a friend of mine test drove a c6 convertible (z51 6sp, i think) - said the low end performance wasn't that impressive - NO FLAME HERE. now, my understanding is that, from a performance standpoint, the z51c6 will damn near run with the current z06 - again no flames here i'm not sure of the stats, but the ls2 is rated at 400HP @ ???? rpm, and the torque is ??? @ ???? rpm! i'd just like to compare that to the current z06.

I haven't seen the graphs for quite some time so I can't give you the specifics. I remember that the torque curve looked surprisingly strong in the low rpms on the LS2 though.

That was backed up by my drive in a '05 vert. The low end performance was impressive to me (and I'm used to close to 500hp in my C5).

Do a search for a forum member 'Scissors', as he had the graphs posted from the GM introduction. I believe there is a direct LS6 versus LS2 overlay. The LS2 definately has a fatter torque curve that comes on stronger faster.

Nice graph. Remember that the C6 is heavier than the Z06, probably by 150 to 200 lbs. Even with the better tq curve, that weight matters.

Someone else posted the GM data but another interesting
source for this is the article at:

http://hotrod.com/techarticles/113_0504_ls2/

This includes a dyno pull of a stock LS2 wherein they
duplicate the GM hp rating (make sure you read the stuff
on the SAE correction factors) and provide a numeric
table of the data.

Last published numbers I saw were 3106 lb for the C5 Z06 and 3179 for the C6 Z51 coupe. Which of these is incorrect?

Okay, thanks. The Corvette Black Book shows the same weight for the 2002 Z06, but has 3106 lbs for the 2004 Z06.

those curves need some work. No wonder ppl want the LS2 edit.

Torque curve should be flat. 380-400 ftlbs from 1500 rmps up to 5500 where it crosses the HP curve. The HP curve should climb to 6400 then drop. if redline is 6500 RMPs

Pretty stinking close no matter how you slice it.

Of course, we'll have our tails between our legs when the new Z06 comes out.
