In order, the top five spots currently belong to a 2018 Porsche 911 GT2 RS (1:21.08), 2018 McLaren 720S (1:21.75), 2018 Lamborghini Huracán Performante (1:22.53), 2015 Porsche 918 Spyder (1:23.54), and 2017 Ford GT (1:23.69). In sixth place by a mere 0.01 second, the 2019 Chevrolet Corvette ZR1 with the ZTK package made a 1:23.70 lap. With Chevrolet on hand to support the effort and three sets of tires sacrificed in the process, it was the best that car could do that day.
IMHO the ZR1 did well and exactly like it should "on this track" considering the extra cost of technology and/or "lightweighting" of the cars that completed quicker laps "on this track". There may be explanations why the car could have been quicker but for the most part I think the lap times represent the primary reason the ME is coming.

I will say what EVERYONE should be thinking here.....the chromies are holding the car back.* Twitchy chrome wheels.* First Belle Isle, now Willow.* Possibly the crazy taillights, but certainly the chrome.

I love the ZR1, but it is just too heavy. Drive a car like my FR-S(2,750), then get in a 3500+lb car, and they just feel awful. Power not withstanding.

Zr1 has two track records that I know of. Randy set one of them, so it may not be wise to blame him just yet, lol.

The ZR1 SPANKED the Z07 by more than a second on an 80 second track... that is HUGE! The ZR1 is a bitchen ride, and going to win on some tracks and lose on some others... but it will hold itself well, and while I'm getting a GT3RS... I won't take any encounters with a ZR1 lightly, and give them my respect.
I'm a fan, of both the ZR1... and Randy Pobst's driving!
Best Regards,

Dave -
A poorly veiled shot at me. I recommend you learn more about the PTM before commenting on it's efficacy. PTM isn't a nanny, as I've said multiple times (to the point of being a broken record). The Corvette Racing team's young Mr. Milner demonstrated that for us with the C6 ZR1 (I believe) a few years ago. With PTM on, he was faster. Call out Tommy as not a "most pro" if you'd like; let's see how far that one gets you.
No pro is faster than the PTM. I'm sorry if you think you're qualified to say otherwise, but you simply are not.
Now, that out of the way: let's be clear that I'm not blaming Randy. I was merely wondering if the twitchy feeling he complained about was due to him trying to push too hard and not using all of the tools available to him. He's been known to think he's better than the PTM and he isn't.

Maybe a better compromise here... would be... whether it's faster on or off... at these levels... for experienced drivers/pros... the 'time improvements' are hundredths of a second, to maybe a tenth one direction or the other. It's not like turning PTM Race on, is going to find a top caliber driver another 1/2 a second, and thus those calling out Randy's time due to not having PTM on is irrelevant to his actual lap time. (IMO).
I'm sure I'll get a chance to drive a ZR1 at some point, and I'll plan to do some laps with PTM on and off, and report back.
Best Regards,
Dave

Frankly! ;)
JVP I wasn't calling you out... frankly don't even know you. If truth must be told... my 'shot' was to JG! While I don't always 'trust' factory driver's... as they are paid spokespersons, making sure they remain employed. I remember Tommy's test with Road and Track, and I think it'd be remiss to not mention he WAS faster than 4 out of the 5 available settings, and that while he did beat his time on that portion it was by .05 (hundredths) of a second.

Sorry folks! The car is only twitchy when he is not taking responsibility for it by disconnecting its system, all or in part.
Maybe You have to be a run of the mill user type to see that.

Glenn,
Just to confirm, you're not even a "run of the mile user type". You have never tracked a C7 Z06 or ZR1, or a Corvette, or ever even been on a race track. But you have Google, so you can be a self-professed expert.
Watching you argue vehicle dynamics with somebody who has won SCCA and NASA championships is comical, at best.

Well the ‘fix’ to the C7 Z06 cooling issues is a porky 3650lbs with the ZR1. Now everyone is pissed off at how heavy it is.😒
I’ve said it before, what we needed was a 3300 lb N/A 550 - 575 HP C7 with ZR1 Aero. This combo would quite simply decimate all.
Maybe we should all get a C6 Z06 with good Aero and call it a day. We all know a properly equipped C6 Z06 can do 7:04 at the ring.

Interesting that he didn't seem to understand certain particulars of his new car though. I'm guessing there's room for some humbleness in some of us?

I see no mention of the fact that the ZR1 was running on 91-octane fuel vs. 93-octane fuel for the Willow Springs testing. From what has been reported and stated by GM, the ZR1 is going to be more octane-sensitive than the Z06.
From what I've read, the Dodge Demon and the upcoming Hellcat Redeye are similarly sensitive. This is what happens when you're making ~2 hp/cubic inch.

Glenn,
I'm sure Dave needs somebody who has never even sat in a Porsche to explain the chassis control systems of his 991.2 GT3 to him. In that case, you're well qualified.

The 12.9 miles is just the Nordschleife (what most quoted lap times are). The GP-Strecke is another 3.2 miles on top of that, so a full lap is just over 16.

casual owner of Z06
Can't run from weight. They tried with a lot more downforce and HP to overcome the drag penalty but the weight is still there.
For owners, if the car has a twitchy nature this will make it even more difficult for casual owners to push the limit in stock form. Driveability is something people should consider alongside laptimes. Just because a pro is able to put down a time while dealing with a nervous car doesn't mean that it's a good fit for most owners doing trackdays.

No one has contacted me so far.

Disallowing and/or lieing about a subject matter would seem to set a precedent towards ones invalidation on said subject. IE

A Grand Sport with 575 NA hp would be a great ride, no doubt. I am sure a number of people in the forum have built that car. It wouldn't compete for lap records with the very top sports cars at Willow Springs though. The power to weight ratio is too far behind cars like the 720s and GT2RS. And the ZR1 too.
