I'd have to agree there. I've driven a ZR1 and there is NO lag. Just pure acceleration. It is everything it's supposed to be.

I punched it in first at a low rpm and going maybe 10mph. It felt flat compared to my car. It did accelerate ferociously once the rpm got up higher. I think the ZRI may be geared a little higher than the Z06 as well - more for top end. I would need more time in it to make a good comparison.

I drive both a good amount and they are completely different cars the c7 z just feels pretty insane in cold weather you can tell a difference and feels more conformable to take turns. But the c6z on the other hand is just more raw and race car feel thing pulls on straight away's but in corners I preferred the c7z allot. Now for looks i dont know how to explain it but you are nuts if you sit here and say a c6z looks better than a c7z,,,,, thats not true at all lol i think they both look good but not better than the other its like in they're own class c7z has its great looks but so does the c6z. c7 looks more exotic and the c6 more classy. But if we did a world vote its obvious the c7z would win by far. no question about it....


Edit: oh and the c7z does have a weird little lag but once it goes it goes, also it overheats a good amount.

Who cares what you hate coming across?

See how that works?

Giving yourself way too much credit here bud

I am sure you have driven your fair share of cars and Vettes. But if you are going 10 mph in first gear in a ZR1 and you punch the throttle and the car is running as it should there is ZERO lag.

The tires would be roasted if you don't roll into with the right touch.

keeso6z

Not really. My C6 Z is my first Vette, although I did drive a C7 base model years ago and I thought that was fast at the time. I need more seat time in the ZR1 to make a fair assessment, but on both the first and second gear punches it felt flat to me compared to my car. But when the super charger did kick in there was a rush of acceleration. It's probably because the rpm was lower when I punched it. I really don't think that car would hang with my Z. I'm making 526whp, but it just feels faster than the ZR1. If you look at the road test specs there is only a .2 second difference in the ZR1 and the Z (both stock), or 11.4 vs 11.6 I the quarter mile and 3.4 vs 3.6 0-60. This is pretty astounding when you consider that the ZR1 makes another 133hp. I just didn't think that .02 seconds was worth the extra cost at the time of $30K over what I paid for my car. But I love the ZR1 and would like to have one because of the exclusivity. As far as the performance, my car is now making another 114hp+- over a stock Z and that should more than make up for the difference of .02 seconds. My guess would be that it is a high 10 second car now. But with some minor mods to the ZR1 you are up to 630hp and it's a new ball game. If I got one, I would immediately get that done. The ticket is to have them both. I just don't want to give up, or take a beating on my Z to get a ZR1. However, considering they were $125K new, they are looking better all the time now at half their original cost. I may give them another few years of depreciation and then pounce. Sooner or later they will bottom-out.

NotreOkc

That is your assessment and it is fair. I guess we each have our own feel for a car when driving it. I too owned a C6 Z for 4 years before getting my ZR1 and I can tell you from my perspective there is no comparison. The ZR1 makes around 500 lb feet of torque by 2300-2500 rpm's or somewhere around there which is more than the Z06 makes at its top end. Of course if you are modded then that changes the game. But an Evo can beat us if you put enough money in it. You are right about the exclusivity and that is the main reason I stepped up.
But I will have to completely disagree that the ZR1 is EVER flat in 2nd gear. It is a postiive displacement roots supercharger for a reason. ZERO lag. I felt no difference between my Z06 and the ZR1 as far as response time. It is immediate. And there is no comparison between the cars. I guess unless you want to look solely at 0-60 times. The ZR1 is not much faster to 60 but it is faster which should tell you zero lag.
I will completely agree with you on modding the LS9. A pulley, intake, maybe headers and a tune and you are probably in the 700+ range, give or take. It is very easy to make considerably more power. I plan to once my extended warranty runs out. Cheers!

With all due respect, your numbers seem off. Doesn't look like the Z06 is that far behind a ZR1 (stock to stock). See: https://www.corvetteforum.com/forums...post1591323101

NotreOkc

Pretty sure I said that didn't I? I said if all you look at is 0-60 times then the cars are close. If you take the entire picture into consideration then there is no comparison.
We know there are different dyno's that will report different metrics. I have reviewed many over the years and they are all in the neighborhood of what I stated above.2000 rpm:
680.8 Nm / 502.1 lb-ft / 142.6 kW / 193.9 PS / 191.1 hp
2100 rpm:

2300 rpm:

The Z06 and ZR1 should be a good drivers race under 100 mph. But above that there should be no question as to which is faster. The trap speeds tell the story.

I wasn't referring to the 0-60 times. Those aren't comparable since the cars have different tire compounds from the factory.

However, in looking at various sources of stock ZR1 dyno graphs, most of them I saw were much lower than 500 rwtq, about 430 rwtq at 2300 RPM. Additionally, the Z06 graphs I was able to find (including my own) show around 380 rwtq at 2300. So yes there is a 50rwtq difference, but by no means is there "no comparison".

keeso6z

For the street, 0-60 is more what you look at. In that case, if you really want the fastest Corvette at an attainable price for most people, the C7 Z A8 would be the way to go. It does 0-60 in 2.95 seconds - that is if you can get traction. I've never driven one and don't want to be lured over to the dark side in the C7 section (just kidding). I know they kind of fall flat up top compared to the C6 Z and ZR1, but down low they would be hard to beat with our cars, even modded. Just so much torque.

SPDKLZ1

Yeah, right. NO comparison. Good one!

corvettejoe09

I agree strongly with NotreOkc. I had a C6 Z, now I have a C6 ZR1. I don't know how keeso6z came up with his assessment.

This is with post 13

Well if you take a c6z and c6 zr1 and look at the nurburgring times there is what 1 sec difference over an 8min track length? So the ZR1 is about .02% quicker around the nurburgring as a real rough estimate.
