Maybe the ZR1 does hold the record, not sure, could probably look it up. But, the thing about those clips is that it's all the same driver on the same course. The record is probably held by a different driver but if this other driver also drove the other cars how would the numbers come out? I just put these on because of the previous posts saying that the 458 was faster and if you look cafefully at the drag race posts that was put up you can see that the Z06 was toasting his tires for the first 50-100 feet and still came in 3rd or 4th, almost like the driver was trying to lose. Also, another point is that if the C7 beats the C6Z then it's going to be better than all those other cars (hard to believe). Even though I own a C6Z I have no problem with the C7 being as good as it can be

From the link:
"1:33.70 in the ZR1, besting the old record of 1:33.99 set by Chris Winkler some three years ago. Winkler managed the task in a 2010 Dodge Viper ACR."
Driver of the ZR1 was Randy Pobst
So a record is a record but different drivers throw off the numbers to some extent.
By the way both are faster than the Z06s 1:34.4

Randy Pobst drove the ZR1 to the record and previous record holder was by a Viper driven by Chris Winkler that's what I was trying to say. Randy Pobst also drove a Viper but was not able to best the previous record with the Viper. The point I was trying to make is that if Chris Winkler could drive the earlier Viper faster than Randy Pobst could drive the later Viper, maybe he could have driven the later Viper that Randy Pobst drove even faster. Is that confusing enough

Since when did I say it was 75%? It was actually Dave Hill, chief engineer of both the C5 and C6 who said that. Someone with much more credibility than you or I. Then the quote was from MotorTrend who validated the claim during the actual performance tests.
I don't think anyone here really thinks a C6 is literally 75% of a C5 Z06 and I do believe the quote was misleading. However, the point has always been it was NOT a drivers race and they were NOT equal in performance. That is a FACT. There is NO performance benchmark that the C6 was better at than the C5 Z.
And you criticize me for not providing facts? Did you even bother to click on the link to the article that was posted? You know, the article with the FACTUAL performance benchmarks between the two cars? The one that shows the C5Z was better than the C6 in handling, acceleration, and braking?
Where are YOUR facts that suggest they are equal in performance?
Then you put out some desperate assertion that I want to 'defend' an older generation Z06 car I've never owned because somehow it makes me feel better about my own? Am I really defending anything, or is it you who is defending an incorrect wishful belief that your very own C6 has equal performance as a C5 Z06 and gets upset when someone disagrees?

It's very likely the C7 base could match the C6Z in weight or even be slightly lighter.
From the ZR1 information page;
We also know the current C6 versions weights.
2013 Corvette Coupe 1LT weighs - 3,225 pounds
2013 Corvette Z06 1LZ weights - 3,175 pounds
2013 Corvette ZR1 1Lz weighs - 3,333 pounds
It's also been highly discussed that possibility of some of the more exotic carbon fiber and magnesium components from the ZR1 moving down to base.
So lets say the 3,225 was their basis of development point, subtract the 138 lbs for the aluminum frame you have 3,087 plus lets say "some" carbon fiber parts because otherwise it's too expensive. The Z06 hood as cf weighs 11 pounds less than the fiberglass version so realistically you're not going to see huge weight savings, maybe drop the car down to 3,050 total from those changes.
We also know the new LT1 produces torque on par with the LS7 so in terms of initial starting force it could very likely be on par.
HOWEVER... the C7 is going to be more technologically advanced than the C6 meaning more weight for components in the car. So I would be very surprised if the C7 weighs less than 3,100 lbs.
Also a big negative in terms of performance for the C7 base versus the C6Z is going to be traction from the tires. The C6Z has larger rear tires that are stickier. The C7 might have some technowizardry for launch controls but I still think the C6Z will grip better.
From the ZR1 information page;
One example is the aluminum frame structure (the same one used on the C6.R race car), which weighs 138 lbs. less than an equivalent steel structure.

Does anyone's answer change now that we know it will be over 471 hp?

In the road and track thread with the magazine pics scanned, the guy with the magazine says he wont post the full text yet but that he'll confirm its 471 hp
