C8 z06 vs C7 ZR1

Wasn't that a Chevy "Mark" that put the C7 ZR1 in the wall as a pace car for the Indy car race in Detroit?

^ Right now a C8 Z owner is thinking.....hold my beer, this theory must be tested.

It was Mr Reuss driving a C7 ZR1 pace car. I'm sure he just wanted to demonstrate how unsafe a front 755 hp engine Corvette is and it's time to move to mid-engine configuration.

I raced for 40 years in SCCA and IMSA. I quit wheel to wheel endurance racing when it took 3 weeks for my body to recover. Having raced "race cars" I know that great street cars are not race cars. For me, I enjoy the casual track days and am satisfied that I still turn good lap times in my street car. The last second or two isn't a big deal for me. When I drive 400 miles to the track knowing my front R888s are on their last day in my HCI stock suspension non-mag C6Z and I'm lapping the same times at Willow Springs that the two C7 Z06 guys rolling their cars off the trailers with brand new Hoosiers are running, it makes me smile. If I was serious about lap times, I'd need to drop about $25K into the suspension.
My C8Z will not be a Z07, but it will have CCBs and I hope Gyrodisk makes iron rotors that I can use for track days. Lifting the golf clubs over the Z07 wing was not going to be fun. My wife said no to the big wing and was really happy about all the rest of the car. WIN,WIN,WIN.

^^^ Got you. So, you're just planning to embarrass Z07 cars with your non-Z07 Z06! Driving experience is good for another 10 seconds.

Watched this video a while back . StreetSpeed 717 gets wealthy with big benefits from his videos ....He starts with supposed stock then mods up incrementally getting his follows...almost like a sponsor.
First view I thought as soon as the ZR1 pulled 1-2-3 he lifted. Then after the race they began talking about a bumper.
On the street with 715 Torque....hit at the right RPM that ZR1 as it pulled and would've kept pulling with 100HP more .....and at 130+mph there might've even been a gap.
Track ET is another thing. 60ft being the absolute key. C8 Z06 wins.
But the street with 20 -40 mph rolls is a whole different world....especially powershifting a manual with 470tq vs 715 ...then 650hp vs 755 advantage + 100 lbs curb weigh advantage for the ZR1.

lightening lap is just a consideration as same car same driver is probably 2 s slower in the afternoon. only thing matters is how fast you are with your car. take it to the track and enjoy it
I watched both participants’ videos and both agree the ZR1 won by “a foot and a half” according to HPObssessed’s video.
He said he shifted “no lift” in each instance..both participants seemed surprised at the Z06 ability…
I said to myself while watching both that the Z06 will run and hide from that manual ZR1 on a road course and I would not have thought that could be possible due to the blower and extra Horse Power of the 6.2 vs 5.5 liter motors…The differences will be the faster shifting C8 automatic vs manual shifting the Z06…meaning the Z06 will be under power for a longer period of time than will a similar manual car.
After 5 laps the Z06 will be way ahead…an auto ZR1 will likely be closer to the c8 auto equipped Z06 because its automatic will also shift faster than a human and be under power longer per lap than the manual transmission car.
I would not have believed this close outcome before today’s videos…the Yellow Z06 had muffler and cat converter work that DID help by about 24 rwhp vs pure stock number on The SAME Dyno a day or 2 before the work was completed.
Bottom Line: this new Z06 car is amazing…to run with a ZR1 as close as it did, you too should be impressed…this was a roll race to likely 120ish…
A road course Racetrack will see quicker times in the Z06 than a manual ZR1…is my forecast…we shall all see in the Spring or at next year Lightning Lap Competition.

The last few posts brought back this old thread.
I now have my C8Z, non-Z06 (02/23). First hand results - straight line. September 2023 at Ely NV, elev 6500'. 1-mile standing start event on an unprep'd two lane back road. 1. C7 ZR1 - 174.1 MPH, 2. my C8Z 172.5 MPH, 3. 2020 Shelby Mustang GT500 - 169.7 MPH.
I was very pleased NA going against these two supercharged cars at high DA numbers. My full HCI C6Z typically ran about 1.5 MPH faster than that same ZR1 at that venue.
No road course times yet. 1/2 mile at Gila Bend (800' elevation with rough paving in the launch area) was 153.5 MPH The PDR 0-60 was 1/2 second slower than up at Ely, NV.
My times were on the OEM PS4S ZPs mounted on Forgeline DR1s.

I currently own two C7 ZR1's and had a C8 Z06. I sold my C8 Z06 after four months of ownership because it was an undependable piece of crap that spent more time in the shop than in my garage. But anyway, that's another story. I can say from experience, that both my C7 ZR1's feel a lot faster than my C8 Z06. Now, I admit, I never raced them against one another, but even my wife mentioned how the ZR1 is '"scary" it's so fast and the C8Z just doesn't have the raw, brute power feel of the C7 ZR. In terms of driving thrills, the C7 ZR1 is by far the best I've ever driven! So much power and it's instantly on tap at any rpm or speed. Even if my C8 Z06 wasn't such a lemon I still would have parted ways with it because after driving my ZR1's the C8 was a letdown. I was originally planning on buying a C8 ZR1 when that came out, but after I experienced what a disappointment my C8 Z06 was, no way I'm going there. From what I observed, it's built out of cheap parts, is poorly engineered, and sloppily built. I guess GM did that to keep the cost down, but that killed the overall quality of the car.

Occasionally, randomly, the backup camera on my C8Z doesn't work, 5300 miles on it. Other than that it has been wonderful. Sorry you did not enjoy yours. Generally, the C8 materials and workmanship are quite a bit above that of the C6 and C7.

I think the z06 for what it is at the price point was very fair.

My C6Z had an aftermarket ZR1 style splitter and the factory available full width rear spoiler which was lower at the sides than the ZR1 spoiler but maintained that lower height across the full rear deck. Ride height was stock

With full HCI and that aero set-up, in 2018 I did two passes at the Mojave 1.5 mile standing start event at 201.2 MPH. DA that day during the runs was 4600'

Looks good!
