Their procedures answer your question. What bi-directional drag strip have you been to? So not a prepped track. And as explained, corrected for conditions.
It appeared you were assuming that CD don't know how to launch cars, despite testing hundreds of cars each year and having only one guy who tests acceleration on most of those for years running. He has a hell of a lot more drag launches than a recent youtube sensation, lol. But they do normalize their test data to account for weather variables and that might explain their times a bit:
OMG, So you are conveying something to me that I already knew about for years. First of all I never doubt the information from CD. I have been reading their magazines for years. And CD very seldom or never reveal time slips. The numbers in the magazine is fine with me and to everyone else. Now since you know so much about CD then you should know if this particular C8 Z06 drag strip test was done on a prepped or non prepped track or were the numbers corrected in relation to conditions. That should be a plan and simple question. Everything else you have already explained. Thanks

@PRE-Z06 You are correct. Here is a link to the Car and Driver article from September 2021 titled "These are the Shortest-Stopping Cars We've Ever Tested" - https://www.caranddriver.com/feature...%20four%20feet.
Take a look at the stopping distances of the C7 GS/Z07 , C7 Z06/Z07 and C7 ZR1.

Aftermarket builds have a lot more flexibility than something that has to meet emissions regulations and are factored into the CAFE BS. Also the fact that a production car is going to get an engine that is generally expected to last the life of the car.
They just aren't even comparable. Sure, it can be done. But will it last 100k+ miles?

The aftermarket? Now that is hilarious. The FACTS are that the C7 Z06 could not be tracked for more than several laps at a time. The way GM MADE THE CAR! The C8 Z06 has already done multiple tests on multiple tracks, and it never overheated lap after lap after lap. It has an abundance of radiators so cooling isn’t an issue. And the C7 ZR1 will lose power the hotter the temps. Won’t even be close. I ran my base C8 very aggressively on some nice backroads today, and the oil and coolant temp never got above 175-180.
Tadge said in a 'qualifying' (or hero lap) the C8 Z06 will 'hang' with the C7 ZR1 (meaning slightly slower). After a 20 minute session the average lap times will be faster with the C8 Z07 (with its improved tires). A C8 Z06 without the Z07 package does not have the sticky tires to compete. C8 SR is clearly not in the same league (from my personal experience). These are the facts.
I tracked my C7 ZR1 and once I get my C8 Z06 I will let you know how close they are the way GM MADE THE CAR. I believe the type of track (tight turns vs. long sweepers), tires and drivers will determine which will have a better lap time. It will be very close!
GM needs to build a TT LT7 C8 ZR1 with active aero to make a big performance difference.

And you know this how?

As you noted - On tight turned tracks that are more slippery in nature, I do expect the ME platform to shine (As it has done with other manufacturers models vs our extinct FE C7 ZR1s). At longer tracks, the C7 ZR1 will give it more than it can handle and walk it lap after lap. And note, I did not mention a tire change from our Cup2s to the Cup2Rs on the C7 ZR1... (Those tires will be available for the C7 Platform soon).
I am waiting for the C8 ZR1 (If it comes out). If it does not, then I will gladly purchase a last year C8 Z06/Z07.

c8z will be faster than c7z on track mainly due to extra downforce and stickier tires. But a well driven c7zr will outrun a c8z. Expecting a c8z to be faster than a c7zr on the same tire is dumb. It’s a 100 hp advantage with same aero and same weight.
the tire advantage makes any “out of the show room” comparisons dumb. Cup 2 vs cup 2 and cup 2R vs cup 2R are the valid comparisons.
in amateur racing leagues, like NASA, you can add 140 hp to a z06-weight car when running cup2s vs cup2R. That’s how much the tire advantage is.

For those who are interested, results of the previous car & driver corvette tests:
C7 Z06: Quarter Mile: 11.1@127, skidpan(300ft): 1.19g, 0-60: 3.0, 70-0: 128ft
C7 ZR1: Quarter Mile: 10.8@135, skidpan(300ft): 1.18g, 0-60: 3.0, 70-0: 134ft
C8 Z06: Quarter Mile: 10.5@131, skidpan(300ft): 1.16g, 0-60: 2.6, 70-0: 139ft
The C7 tests also dont mention anything about a '1ft rollout' like the C8 test does

That is what mid-engine traction does for ¼ mile times.

Back roads lol. Have you ever been on track? Just about any car can handle back roads driving. The 2017+ manual z06s did just fine on track. Many many cars out there get hot on track.

LOL, yeah backroads. The kind of road with no houses or cars. 15-20 MILES! As you may or may have not noticed, I have a LITTLE experience with the Corvette. Both FI and NA. And a supercharger creates HEAT. That is why the C7 Z06 -couldn’t cut the mustard. Not enough cooling. The C7 ZR1 obviously was a lesson well learned from the failure of the C7 Z06. May buy one if prices go down. But the C8 is a superior car. Base and Z06.

You can eat up a set of tires in 2 hours or less on the track. Same tires could last 4,000 miles with most aggressive street driving. Similar big difference with oil temperatures, lifespan of brake components, etc.

Just out of boredom/curiosity I was comparing these numbers to the Car and Driver test results for the GT500.
It looks like overall, the Z06 is considerably faster. But when you calculate a "roll race" from 60-130, they are basically neck and neck.
I know this isn't the car for roll racing/drag racing/any other form of racing that isn't approved by the forum snobs. No need to jump my *** over it. Just comparing the two cars as the GT500 was a bit of a "Plan B" car for me, but I'm just not really feeling it.
