Now that we have solid numbers, lets talk performance

There are the 'average' numbers (also known as: "magazine times" and/or "manufacturer's data") and then there are the all out bests (also known to some as: "hero runs"). 
One needs to be specific which one they're actually looking for when asking what they think a particular car will do.
I remember the good ol' days of 'C6 Tech/Performance' when we all used to debate this crap LOL.
Bone stock (including tires) C6 LS3 A6s have gone high 11s.
And while I agree that many (most?) will only run in the mid 12s in their stock C7s, I don't think it will be 99.5% of the time.

Why do so many people think the Z51 will have a quicker 0-60 and 1/4 mile than the non-Z51 C7?
The power is the same in both, and the weight will be pretty similar, Z51 actually have a slight weight disadvantage.
What am I missing?

I agree, the "Lighter" base car should be quicker!

Question to the pros: would the larger rims / design of the Z51 make a difference? Would the wheels on the Z51 be a little lighter with the thinner profile?

The C6 GS and the C6 Z51 has the same lower gearing as the C7 Z51 and the base C6 has the same gearing as the base C7. That's why the C6 GS is quicker 0-60 and the 1/4, even though it's heavier than the base C6.

I may have been misunderstood - I posted Z51 NPP in response to another poster JoesC5 who referenced Base vs Z51.

Also, thanks for transmission gear ratio info in the previous post. I never took the time to check it out; I didn't know. I thought you only get gear choices with the Automatics only.

It will be a 11 sec 1/4-EASY. My guess is 11.5-11.8 based on the track and altitude. 120mph+ trap close to sea level.
I drove my 2001 C5 Z06 to 12.27 @ 116mph and my 2006 C6 Z51 LS2 to the same time 12.27 @ 116mph. Both these cars had cat back, intake and tune nothing else and on a crap track. I did get 1.8 60' in both cars running the run flat pieces of crap in the C6 and Michelin PS2's on the C5 Z06. And the C7 will have GOBS more HP and torque then my 385 hp 2001 Z06 and C6 400 crank hp motor. My C6 dyno'ed to 385whp at the wheels uncorrected.
But it won't be faster then the C6 Z06 no way! BUT I hear the PCM is cracked so with E92 tune it will be close to C6 Z06 whp then I think
I am not a drag racer, I want it to keep up or beat the C6 Z06 around a track. I will do track days with it.

Hope the new tires live up to their expectations.
I'd expect a 12.2-12.3 @119 at our local track. For comparisons sake my 2010 Grand Sport went a best of 12.61@116 out of 4 or 5 passes.

Gearing. The Z51 manual transmission has lower gearing in the transmission, and the Z51 automatic has lower rear axle gearing. The lower gearing increases the engine's torque to the rear wheels.
The C6 GS and the C6 Z51 has the same lower gearing as the C7 Z51 and the base C6 has the same gearing as the base C7. That's why the C6 GS is quicker 0-60 and the 1/4, even though it's heavier than the base C6.

I'll say based on the hp rollout of greater than 450, the 0-60 time of less than 4 seconds means 3.9. I will agree with the others with the 12.2 1/4 mile time.
The majority of it will depend on the driver.

Yes it will. It remains to be seen whether its more advanced than the C6's pretty basic setup. I think a good driver will be able to beat it again, until they are able to get a DCT trans with LC in it.
