UnhandledException

Jim,

What's your take on this "R" compound Porsche specific Michelin Cup 2 tires? I bet if ZR1 wore those tires, tires were warm, and conditions were ideal, ZR1 would run a sub 6:50 ring time and go head to head with GT2RS.

It's great to see you post on this forum. It's even greater for me to be able to quote your post You are a legend

I don't think the zr1 can go head to head with the GT2RS. Weight, 4wheel steering, dct prove the RS is superior.
Also from what I remember the RS dynos a little under 700hp to the wheels. So crank hp is definitely higher that what they claim.

ZR1 is not a 755 hp car under majority of the circumstances. ZR1 is a 755 car with 91 octane gas 4000 ft above sea level. With 93 octane and at sea level, I think it is easily over 800 hp/740 torque car.

GT2RS weighs 250 lbs less than ZR1. It's not a lightweight car by any means.

The Ring time may not matter to 99.999% of the 7.7 billion people on Earth, but that means approximately 77,000 care about the time. That's quite a few and I'm 1 of them. Thanks Jim!

I'm surprised, I thought that when we finally found out the time it would be quicker than the Viper ACR that did 7:01 with a manual transmission and 110 less hp.

If I had the money, I would fly jim there own my own dime, get a car out there, rent the track, and do this properly for ZR1 once and for all. I think the manual transmission ZR1 is a 6:50 capable car. That says a lot for the chassis. Porsche has way too many electronic advantages.

When I read "cold tires", I was actually amazed how it pulled 7:04 time. Have you driven a ZR1 with cold tires? I have and it's not fun at all. Car breaks traction in 4th gear if you are not careful.

ZR1 was already dyno'd by:
hennessey - 654hp/645tq
https://www.thedrive.com/news/22854/...-at-the-wheels
630hp/626tq

Acceleration isnt close either, the ZR1 is more equal to the New Ford GT, while the RS is closer to a 720s. 720s easily leaves the american cars behind.

Welcome to the forum Jim Mero. Its great to have you here!

"Nothing" is a little too much of an absolute. I was looking for a new, modern, American-made track car. I cancelled an early C7 Z06 order and later passed on an available ZR1, not because of a poor Ring lap time, but because GM had both cars there for extensive periods of time and NO time was forthcoming. That raised red flags - possible overheating, handling issues, poor performance compared to the competition - who could tell???? I am glad to hear that both cars performed well. I just wish GM had been a little more upfront at the time - it would have gotten them at least one more sale.

Still a Corvette fan!

Valid point...but your's seems to be an issue with a lack of Ring times, not Ring times themselves.

There were lots of press before the ZR1 was available where the target was sub 7 minutes on the Ring. If they would have come out before the car was available to the public that with all of their testing and development, the best actual time on the Ring for the ZR1 was 7:04, would that have made you say "Not buying the car because of it's Ring time"?

Even if you're "vague" we still love ya, Mero!

mfain

You are correct. It was the lack of a Ring time and the way GM was handling the situation that bothered me. The advertising hype at the Z06's release didn't help. As it turns out, I think I made the right decision on the Z06 due to subsequently identified overheating issues. And in all fairness, by the time a ZR1 time could have been released I had already purchased an American-made car that had demonstrated a 7:01 at the Ring and was proving to be quite competitive on the local tracks. The ZR1s 7:04 is an excellent time and is an indicator of the car's potential.

Super cool having Jim Mero reply to this thread (even with his name dropped in the title)! Thank you for chiming in, Mr. Mero!
I really enjoy lap times wether it is the Nurburgring, C&D Lighting Lap, or just people on here posting times/videos. It is a fun way to compare all aspects of different cars that more simple things like drag racing can't provide.
I like the Olympics comparison that was brought up. That said, it isn't even close to as regulated or as easily repeatable as a 100m dash. I have absolutely no doubt that the ZR1 is a 6:5x car and wish GM would have stayed until they proved it. I'd love it if they took a ZR along when they have the ME car over there again but I fear that we will have to resort to a Viper-style crowdfunding effort if enough owners/fans care about putting our car where it belongs as the first American to break the 7 minute barrier.
Until then, I'm happy with the current time by an amazing all-around car!

This "Ring" stuff is a big deal for a very small number of enthusiasts. It is however amazing to have watched guys on forums break their ***** and fight with each other about which car is a Ring bad *** and why certain vehicles have no posted "RingTime". Much of this comes down to which car is north or south of 7 minutes by 3,4, or 5 seconds. Ridiculous even if nobody cheats and all runs are under the identical atmospheric conditions and there is no such thing as human error.

10 seconds is like 2% of 7 minutes. It is really not worth even talking about, stupid.

dsevo

Yeah, that thing is an archaic piece of junk according to many on this forum. Real head scratcher that it's quicker around a high power track where it should have the biggest disadvantage. But, but, tires! Lol.

Jim,

It's pretty damned cool you have become a member of the Forum and have chosen to post. We all know and greatly appreciate your huge contribution to Corvette.

Welcome to the neighborhood.

Fantastic to have you among us.

Oh - and Thank You for all you've done for us enthusiasts.

Let people enjoy things...

And for people saying that "track times" aren't why people buy these cars, that's simply not true. Posting track times is a piece of a larger marketing campaign. Lots of guys out there at Cars and Coffee that love to brag about their ACRs performance, even though they don't track or even drive their cars. It's a you-know-what measuring contest for a lot of guys.

You don't think a guy deciding between a Demon and the new GT500 is going to being comparing their time-slips before he makes that decision?

Sorry, but someone had to do it


Welcome aboard Jim, and good luck on the new venture!
