C7 ZR1 ZTK vs 720S
#21
My point was, this claim of C7 corvette being the super car killer corvette is no longer true. All corvette kills is the 100-200k car segment which is mostly cars like 911 C2S/GTS/Turbo/GT3/RS (although last two are debatable as they will be much better track cars) or M5/M6 or Jaguar cars or maserattis or any other car I am missing in that price range. Now this was a decent price argument for Z06 since it was $80,000 and beating cars 2-2.5 times the price is decent. But when you consider ZR1 is $140,000, its no longer bang for the buck and its certainly not killinng anything 2-2.5 times its price range (i.e gt2rs or 720s).
There are a lot of early adopters here but when these news and tests sink in, I dont see many people buying ZR1. When the prices drop 15-20%, then it might be worth considering however.

I would say that Jim is an excellent driver, but he's out of shape and pushing 50 whereas Billy Johnson looks like a tri-athlete (and maybe is like a lot of pro drivers these days) and is 31. Drivers don't typically get faster after 40. If Ford didn't have the edge in the driver department, then Jim needs to quit his job right now and start circulating his resume.
As for cars, the Ford GT started life as a race car, is not really a Ford except for the engine, and was designed largely around the goal of getting as good of fuel mileage at Le Mans as possible.
So, while your point about the track conditions and different drivers is well taken, if the ZR1 had even been close to the GT would have been impressive to me, but having beaten the GT's lap by a considerable margin with a car that is based on a 4 year old, $50,000 street car design that is confused between roles of sports car and super-luxury cruiser has got to be the ultimate humiliation for Ford fans.

Mclaren at 3160 and ZR1 3600. To add to the issue the ZR1 had a driver that probably tip the scales at 220+ and a passenger who I'm giving 150 on the conservative side. The ZR1 on that day, with those people inside was knocking 4000lbs.

I don't call that a race in any form. The ZR1 seemed like it was broke or just not moving at all. There was no need to race several times when you have a spread like that....ridiculous. After the first so-called race, it was a waste of track time in order for the other guys to run. A mid 10 second car and high 9 second car should have been a little closer than that. My .02

Thats actually true as well.

I can't believe I'm spending so much time defending Corvette on a Corvette forum: you're saying that the ZR1 is a loser because of a straight line drag race? Am I wrong that most sports car drivers are hoping that their cars can go around a corner, also? Don't you remember that the C6 Z06 was frequently matched up against all kinds of Supercars by magazines? Almost always, the Corvette was one of the slowest cars in a straight line, and almost always, it was one of the fastest around the selected race track. Which is most important for a sports car, the straight line acceleration, or the lap times? Ideally, you'd like to have both, but if you have the faster accelerating car and are getting beaten in lap times, that's not a good argument for the superiority of your chassis.
I don't know how comparative lap times between the Vette and the McLaren will turn out, but McLaren has been surprised before in previous tests by slower accelerating Corvettes.

In other news Formula 1 cars can't rally cross for ****!!! Drag races between cars designed for turning corners is asinine. Making conclusions as to the performance of a car even more so.

If you compare the ZR1 you may as well compare a faster Z06 with mods
720 vs stock ZR1? It is apples and oranges as well! Forget it!

The 720 is a beast for sure but everyone wants to forget about the Corvette Z06 which is tunable with mods and with intake, the Magnuson 2300 headers and tune. Tune time performance
installs then on the Z06 A8 with headers and intake and they on stock rubber run in the 9's @ 138-139 faster than stock ZR1's
Several others members like Nic'd have the 2300 as well running 9'8's at 142 at high altitude The 720 I think may have trouble beating Nicks car!
I installed one on my Z06 M7 it made 673 rwhp on a Mustang dyno and weighs only about 3450. (Would love to run a Zr1 m7.) The ZR1's weight no less than 3650 weigh with the additional weight on the nose .

Since you’re such an expert, perhaps you can provide values for each of the following supercars the ZR1 dusted at Willow Springs...
http://fastestlaps.com/tracks/willow-springs
* 675LT (which is an insane car to drive btw)
* 911TTS
* Huracan 610-4
* 488 GTB
* R8 V10 Plus
* Aventador 750-4
* 650S
* NFGT (.01 & smoked at VIR)
LMK if you need help with the commas and/or decimal points😂
C’mon show us your cars hot shot. What seems to be the hold-up?

stack the race? I was invited out to race and lined up against whatever they wanted. The passenger in the ZR1 was lighter than the passenger in my car, we even gave the ZR1 the jump on the first race... 720s is stock, no mods at all... I think the heat effects the ZR1 more than the 720S, but still it's never going to be a close straight line race... even my Huracan gave the ZR1 a hard time that day and it weight about the same and has 150 less HP....

Drag time guy. Love the videos. Great job. Get that Ford gt out there will yuh!
any chance that ZR1 was running 91 octane and had the wing on full attack? Because they run pretty good? Low 10s mid to high 130s? Was very surprised to see it was the bad?
driver of ZR1 was pretty large probably 100 more than you as well?
do you have any stock Z06 v 720s vids?
your garage is killer and all that's in it as well.
livin tha dream. Good for you.

I'm not familiar with the whp in real world but factory has the Z at 750 and the 720 at 710 but you're saying the 720 does more whp than the Z in real world? That would explain a lot. Do you think the 720 has that much more efficient of a drive line or it's just underrated from the factory.

I have seen ZR1 dyno ranging from 630-670whp depending on milage and transmission. I have never seen one make 690whp stock. Anyways given the weight difference between the 720S and ZR1, the ZR1 will need 750whp at least to hang with the 720S and more if it is using ZTK package.

Pretty wildly, in fact. The 720's engine is probably making closer to 800HP at the flywheel. Remember that McLaren doesn't adhere to SAE when it comes to their engines' HP ratings. So they can claim whatever they want.
It's going to be pretty hard for the ZR1 in any trim to compete with that.
