No disappointments whatsoever! Inexperienced Drag racer, unfamiliar with vehicle, using street tires, improperly prepared track, only two passes, shall I go on? This car in the right hands will easily produce mid 10's and mid 130's traps, ZERO doubt about it!
Not everyone can take a 755 HP RWD vehicle ESPECIALLY with a manual trans/street tires and have hero runs right off the showroom floor....clearly if you are a drag racer you understand this!

He JUST got the car! No seat time. Has he ever driven a ZR1 before? NO!

That was SS717 Car he is not inexperienced he has owned a couple of 1k hp Z06s. He has hosted a huge drag event made numerous passes and also has a McLaren 570s, so he has a lot of seat time in High hp corvettes and other cars.

I sure wouldn't have posted that video. There was a brand spanking new Jeep Trackhawk at Bradenton NMCA a couple of weeks ago. He was clicking off 11.2 - 11.4 with that tank. He trailered a new Demon that was yanking the wide fronts and broke into the nines (barely).

Every .1 in 60’ , will give us a 0.20 sec in the end
So considering an average driver maintains 60’ in 1.9 that means the new ZR1 will run 10.8 all the day

The only difference is a Stick other than that the Z06 and ZR1 are pretty damn close to the same car. He has ran many low 10s and I think some mid to high 9s in one or both of his Z06s. He does need practice in the stick. He has a 2nd ZR1 that should be delivered next week, not sure if auto or stick?

Repost. Probably the 3rd person to do so in the last few days.
But besides that...As others stated
Brand new car
Inexperienced driver and very poor launches
Street tires on prep = not the greatest
He made two passes:
Pass 1: 11.5 @ 129.xx with a 2.4 60ft
Pass 2: 11.4 @ 123.xx with a 1.9 60ft
So as you can see, on the pass that would have been fast with a 1.9 60 ft, he lifted before the traps. Had he stayed in it, he would have likely trapped 131-132 and ran an 11.0 or something in that area. The ZR1 he raced in the 2nd pass makes north of 900 RWHP on boost and the 18" tires and better driver (Fran) certainly help. Speaking of Fran, not sure how "Fran didn't help the ZR1 guys much" applies when he didn't do anything but show up and race his own car. What did you want him to do? Get in somebody else's brand new baby and race it?
So all in all, the ZR1 will easily eclipse the Z06 times with time. The Z06 is a high 10 second car bone stock all day long, manual or auto. ZR1s will frequent the 10.6-10.8 range with good passes and hero runs will be very low 10s. Z06s have run as fast as 10.4 on STOCK RUBBER. You can bet that ZR1 hero runs will be 10.2s or there about.
As for aero, owners notice and show differences between stage 1 Z06s and stage 3 Z06s (With the full front splitter/spats and wicker bill in the back), lots of drag north of 110-120 MPH. I bet even the base "small wing" ZR1 has more drag than a Stage 3 Z06. Take all the aero off and run it naked and I bet you can could grab a 10th or two once you're in the 10s. A lot of time is spent north of 120 MPH (For a drag strip run) with a car like that. Precious speed and therefore time is costed.
Finally, to cap it all off, this is a track car. With poor engineer drivers the ZR1 is already setting and smashing records. Hopefully they give it to a qualified driver for the 'Ring laps and the Laguna, Big Willow and similar laps. Put a better driver than the engineer in the ZR1 and probably take another 2 seconds off of the VIR record. The variables go on.

I don't know the guy from Adam, but just owning a few cars that have 1000 HP doesn't mean that you know how to drive them worth a $hit which is evidenced in the video of his launch. Plus, I would prefer to give the guy the benefit of the doubt...mark my words, with good air and a good driver this car will see 10 flat @ 140+.

I'm assuming you're talking about the Fran's white C6 racing in the video? It's a true ZR1 with a stock engine/bottom end LS9. There's lots of videos on it on their channel and he has build threads for it too. It's basically a Heads/Cam/FBO car, probably runs on E/Meth. He has a 150 shot on tap should he need it. Makes 916 RWHP on boost, over 1000 RWHP on spray.

There will be an A8 on DRs running soon and that will be a better gauge.

It's an M7 issue all of them have it! The tall 1st gear doesn't 60 ft well.
That was the Z06. Now even more weight out front and same gearing
and more rubber on the front. It will not be deep is the 10's nor upper 130's.. Highway monster but not a great 1/4 mile car! The A8 will be better.

I have a C6 ZR1 so I'm well-acquainted with an extremely tall 1st gear. It makes the launch more challenging, but the 60' is all in the driver and track conditions. Also considering my ZR1 makes 100WHP less and went 10.60 and trapped 132MPH... There is zero logical reason that car with a lot more HP, similar gearing a little more weight won't be right where I previously stated. It's a fairly simple equation --- X weight, Y WHP = a narrow MPH trap speed range, all things considered..

is the main difference. Stock to stock is not a 100rw less. Track conditions and driver will get so much. My ZR1 bone stock trapped 128
My Z06 with mods 132.

My ZR1 dyno'd ~570WHP with an average trap speed of 132MPH. The ZR1 in question dyno'd 668WHP (and should gain some with miles). The ~100WHP delta is more than enough to overcome the additional weight (190lbs) and drag. It should be at least in the 134-136MPH range. The sample size (1 car, questionable driver, 2 not-so-great passes) is hardly worth debating at this point, but it's all we've got.
Give it a few months and we'll be seeing respectable numbers for the power and weight.

Gutted cats and a tune. My overall point from the beginning is that based on the WHP and weight, etc.. a stock C7 ZR1 should be trapping mid-130's.

Hell yes! Runs with good air for the C7Z are in the mid 130's, adding 5 MPH more for 100 HP isn't a stretch. Granted, I wouldn't expect 140's to be the norm, I would expect most people to see mid 130's as the norm for a "decent" pass.
