Listen.

The video of that 2.7 is pretty suspect imo ...

This look downhill?



those are screenshots of the "2.7" run..


That is a screenshot of some random runs he is making without the passenger who's taking the video.

To me he clearly launches and launches this thing all over the place trying to come up with some clickbait title for views. And he found some good downhill spots.

Do it ONCE in the other direction just once. A bunch ibunches videos out there already and none go the other way. Even when confronted about it.

And if we are going to be more brutally honest?

The body panel gap and fit and finish is perfect etc... is it? I mean you're excited to have it.. but take those rose comored glasses off for a second.

I only noticed this because HE pointed it out and i saw something all to familiar since the C6..



Oh well.
Each gen should be better. And they are. But it's still a Corvette. And it's 60k for a reason. Relax kid (who sounds like he may have some flu like symptoms as he travels all across the land.). Get some rest and stop infecting people.

His 2.8 sec try is almost clean enough to have a conclusion that this car is able to launch hard and get 0-60 (1ft) in 2.7-2.8 sec in ideal conditions. That’s fair enough to me.

Still I’m waiting for someone is using dragy app to confirm some interesting data

If these 2.8 sec guys are already; "rolling, and not from a dead stop?" That's not 0-60 mph 2.8 sec......that's; "from a roll."

do you think drag radials would help 0 to 60 and 1/4 mile times

It may help with consistency, but not on outright best time IMO. This 2.7/2.8 0-60 times seen from numerous owners and media outlets show the car hooking up and going. Traction is not an issue with this car like it has been with past corvettes.

Remember that 0-60 time you're looking at is 0-60 mph, not 60 ft time which is what gets measured at the strip.

Right, do you not think it’s going to take longer to get to 60mph if you run a slower 60’ or vice versa if you run a quicker 60’ then it’ll result in a faster 0-60mph time?

Dumb question, but the computer is calculating 0-60mph/1/4 mile distance off of actual GPS and not wheel speed correct?

It's wheelspeed in the C7s. I don't think anyone can spin the tires in a C8 past 60 yet to figure that out.

You can watch the C7s tainted zero to 60 times on pdr all over youtube. Trying to convince people of a ridiculous time..

Go to 1:15 in this for an example lol

Answered the question in the post above that one.

What are you talking about?

Did you watch the video? That's a C7Z06.. the point is the times are wheel speed determined.

Its how that C7Z06 outsmarted the timer by spinning from 45 to over 60 then it caught traction dipped below 60 and back up again.

punky. what you may fail to realize is - version 1.0 of anything is easily surpassed by 2.0 and beyond. patience.

Knowing that? i love my C7... it's the second one I have purchased new and my third corvette (my other being an 08.. when the C7 came out? i didn't jump right in because it was new and shiny.. but i loved that car from the first time i saw it. inside and out. the C8 EVEN IF it blew my socks off? i wouldn't buy the base car and MOST CERTAINLY not the first year.. I had the chance. and i WOULD'VE already taken possession of the C8.. I went with the best of the known to last me 4 5 years or so until the C8Z shows up. and the great thing is if...IF i don't like the C8Z? i have my LATE 2019 custom built beautiful white with black gut 3LZ exposed carbon inside and out suede beauty... and thankfully it can be modded to as fast as i want it to be so i don't have to time my rolls to somehow TRY to catch a Mustang GT good god...


I am here to learn and educate myself about this gen and so far? i am seeing things crop up and it is a little bit unsettling about the things (the only things) we know so far... The switch to ME was going to be painful and so far? there's a bunch of it.. Trans leaks unable to be repaired needing new trans installed. odd gears non functioning and needing TRANS replacements even though they thought it would be a solenoid.. now there's an airbox failure where bonded panels are causing CE lights? windows functioning on their own, horns going off for no reason and more and more... so i hope that when you receive a C8 it has NONE of these problems, but that's the risk you take to have a "crowd" of children and old men run up to your car and Ogle it... that means nothing at all to me. I actually regret not going with a stealthy color C7Z again.. i went racer and i am hating the attention. just me.

I really wish you guys would just stick to the C8 itself what it is and isn't doing and STOP being so confrontational with ANYONE who has an opinion not in line with your own. it's old. it's really childish as well.

Get over it Dude. The switch to ME was never going to be "painful" and is not "painful". Enjoy your C7, it is a great car.

VERY thankful for the ignore feature. Only problem is, I still see his/her posts when others reply. Oh well.

Dumb question, but the computer is calculating 0-60mph/1/4 mile distance off of actual GPS and not wheel speed correct?
I understood the question as being ET related and asked why the .2 wasn't carried all the way through the 1/4. I was just reminding him that the .2 difference in 0-60 mph is not directly ET related, but mph related. You may or may not run a quicker 1/4 based on 0-60. If you spin the tires a little, you may end up with a slightly slower 0-60, but the extra wheel speed may help you out in the long run. Are any of the speeds recorded by the C7 data recorder GPS based?

My understanding is no, so if it’s based off wheel speed and the distance the car supposedly covers based on the circumference of the tire then if it spins the distance is shortened no? The circumference of the tire is ~7’ so how much is each extra revolution worth if it hits 60mph in ~130’ if it’s doing it the high 2 second range? I’m calculating ~ a tenth, but maybe I’m making a mistake. The distance is the same at the dragstrip regardless of you spin or not which if you don’t move down track you still have the distance to accelerate to your trap speed, unlike with the car timer which is counting distance by how far it’s theoretically traveled based on wheelspeed.

what makes guys think the PDR does not use GPS data, along with accelerometer data to determine speed and other things. It literally creates a map of the track you are on the do lap speeds, track map and position. For some reason you guys think some $150 toy is going to be technically superior to the $1800 GM system. Why? I am sure Cosworth would not allow GM to associate them with crap hardware.

If you think GM is that incompetent you should probably buy from some other manufacturer.

I have no doubt that GM is one of the most incompetent companies of modern times - but I would certainly not say the same about the engineers working on the Corvette platform.

I’m not doubting the PDR uses GPS, but what is it’s accuracy exactly? The timer on dash doesn’t match the PDR people have posted, so is it subtracting the 1’ rollout? Is PDR doing the same? Why the discrepancy or is the GPS accuracy down to 1’?
