The hook was great, but there are definitely better times in there... there is still a fair bit of tire slip on the gear changes you can hear. Should find the low 10s under the right conditions at a good track. Not bad for a 3600lb car on street tires [/QUOTE]
That's exactly what I was focused on in the video. I agree....there still seems to be a bit more with the ET...at least 10.40s which a few of us predicted.
You didn't watch the video? Watch it if you can....that may answer some of your questions.
I have a C8 and you won't see a 2.5 0-60 on average not even on a PDR.
Not a fan as too dramatized for me.

You start the time when the speed sensor moves, you stop it at 60 where it’s not spinning how it got there is irrelevant? With a manual launching at around 5k rpms either the tire spins some or the clutch is slipped or a combination of both, there’s also a shift that has to happen. Could it sure if you’re spinning all the way to 60mph or the timer doesn’t start when tire initially moves. My assumption is the C8 timer doesn’t use the same thing to start as it does to stop.

Again, I know that track well and what a shitty environment it is to put down any kind of a decent ET there. Plus, it was 100F the day they were assigned to run. So... total respect to her for laying down that time, technical assistance or not.

Which do you think is harder to launch a manual car with a 3rd pedal car to a 1.4 60’ or a DCT launch control to a 1.5 60’? All I asked was what RPM was she launching at and what is the max rpm allowed, spare me the drama. The other thing is the clutch engagement can be adjusted though I’m curious how that affects traction management from interfering. If any knows the range of adjustment, I’m curious if you don’t mind sharing.
Please explain how you get 2200’ DA at 100*? Had a guy tell me yesterday his small block made 700hp, I just looked at the carb/intake and header primary size then shook my head.
My prediction for the C8Z06 in optimum conditions is a 10.2 as the C8 went .4 faster than it’s GM published time and it just happens to be what the C6ZR1 ran with drag radials only fwiw.
Just wondering how you know it doesn't have wheel sensors? How does ABS or traction control work without wheel sensors?
I was speaking of the standalone GPS timers like the Dragy. I am quite confident they don't have wheels sensors. If you have evidence otherwise, I would love to see it.
I know it was answered above but yes, in the app when you look at your 0-60 times, you'll see a 1-ft rollout time below in your additional metrics. It's super tempting to use those numbers but, I always tell people I'm slower than I actually am. You never know who is listening and wants to run you. Lol. I legit tell people that I just have bolt ons on my Audi--which isn't wholly untrue. It just doesn't properly outline what's done to it for those who don't know. The C8Z cutting 2.X 0-60's is impressive no matter how you look at it. If it cuts a 2.5, that's really, really impressive for a RWD car. If you've never experienced that or quicker on the street, with an ICE vehicle, it's a sensation to behold.

Got it. That makes sense. I thought you meant the C8 in general which didn't make sense to me so wondering if there was some new tech I was missing.

Here’s an interesting comparison if the C8Z06 did a legit 2.2 0-60mph, then the C6ZR1 with just drag radials was faster when comparing the breakdown of the slips. It’s great the launch control will do what the great drivers can and the C8Z06 won’t pull as much timing as the C7Z06 when it’s not ideal conditions though the back half even given the DA difference is 2 tenths slower than the C6ZR1. 2.8 and 23mph is on the slower side for a mid 10 second car that has a clutch and shifts faster than humanly possible. I saw she had the fronts pumped up and added higher octane fuel, so she was trying different things to help.
Most members with a sane mind know that's not a legit 2.2 0-60 displayed on board. If they do they need to go back to the drawing board so to speak. Now that is one fast C6zr1 which was getting the full power down it appears. But you know for a fact that since this c6zr1 is a manual and setup for the 1/4 mile, there seems to be a driver mod to go with that 10.26@135. I have seen these cars run at the drag strip and most guys struggle to break 10 seconds. If anything the C8Z doesn't have the brute torque as the c6zr1 which is most certainly missing. C8Z is just a different animal.

I think you’d be surprised at how many don’t have experience racing and believe it because they see it. Many don’t realize how fast previous generations did in the 1/4 with a good driver, so they don’t appreciate what it takes as technology does it for them now. LT6 doesn’t make the torque of the LS9, but the torque multiplication from gearing of the C8Z06 is double that of the manual only C6ZR1 so it actually makes more wheel torque though weighs more of course. They make very similar power to weight, so no surprise they run similar numbers.

Don't get me wrong.....I really like seeing manual Corvettes on the drag strip better than I do auto's. It's fun to watch. Okay good explanation on the torque difference between the two cars. Just doesn't seem obvious. And sorry that I misunderstood you regarding the comparison.

No worries, most only appreciate drag racing or road racing and not both. I happen to enjoy them both and have done my fair share of both, only other guy I can think of on here is Dr. Ron who has hundreds of passes at the drag strip in manual corvettes and hundreds of laps on the road course as well.
Track prepped drag strip is not "real world". Ya gotta do it where "we drive our cars". And use a draggy GPS. Then post ur numbers. The 0 to 60 number is very suspect!!

While I understand your point, people are always using their drag strip slips to post times and most people with any clue understand that better times are usually achievable on the strip. Doesn’t make them any less real because the car still has to be able to put those times down relative to other cars in the same conditions. Then you have those “real world” times people post when they are driving down a hill. I think the GM times are more realistic for “normal” street conditions and also gives a perspective on the difference between the Stingray and Z06.

Yes! There are just too many variables on the street.

Yeah. She doesn't have skills or anything...
Anyway, great time and some damn good PR for GM.
The Z is fast/quick that’s for sure and those complaining about Hartford, she’s a far better driver than 90% of the senior citizens on this forum, or most general forum posters. I’m glad GM is working with her.
Stumbled across the answer to one of my questions, 5k rpm is the max for launch control with 4500 being default. Couldn’t find the maximum amount of slip adjustment though if someone knows.

Looks like a supercharged C8 with a drag pack runs similar number though they didn’t use launch control, not sure about it making 700hp(205 more than stock) given its trap speed though.

Making a straight line beast out of the Stingray shouldn’t be that hard but I’d never want that over what the Z06 offers. Personally, if I had my Stingray I would have done twin turbos and transmission upgrade offers by Cicio.
