Top speed OEM?
Hey Gents...Pending my PPI I take delivery tomorrow over in Sarasota...yep I am excited! Anyway just thinking out loud, not trying to set any land speed record just curious from an Engineer's standpoint. I have read that the published Top Speed for the Z06 is 195 MPH. Haven't done much research but I believe that is with the level 3 aerokit (which obviously is going to restrict top speed) and a coupe. My understanding is the final drive is 2.41:1, I don't know what the top OD ratio is in 8th gear (auto), but that can be gotten and I can get the redline RPM number pretty easily along with the tire circumference so can calculate a theoretical top speed but I am asking real world...has there been a top speed test of the stage 1 aerokit in the coupe and Vert? Top up vs. top down? Does Chevrolet have any Top Speed limiter in the vert or any guidance on usage with Top up or down? Thanks for any and all information. Also for those who have driven their vettes up near 200MPH, how does the Z06 feel? My 997TT had a real world TS of about 198 MPH and I had her there a couple times...Dead Solid...but yeah the road got a little skinny.

Your top speed doesn't matter between models as much as your 60-130 or 100-150.

Wouldnt the limiting factor be the fact that its a convertible? Those would have a lower top speed than the regular coupe right?

too speed stage 3 aero is 180 to 185. Top speed stage 1 is maybe 190 to 195 and takes 3 or 4 days to get there . After 150 mph the c7z dies off — no one’s at home.

Let's see, you live in Sarasota, so in my experience, the only high speed roads you have are I-75 and some out of the way places on Rt. 41. Not that I really care, but why the fascination on what the car's top speed is? You won't likely do either of those speeds on either of those two roads unless you are drinking, smoking or shooting something. That comment on 60-130 being important and "fun" is probably the best advice to you. Truly, killing yourself is your decision, but taking someone with you, which quite often happens, you should be punished severely and won't deserve to live. Enjoy the car, don't kill yourself in it.

Sun Valley Road Rally last year I took an almost stock Z06 past 200mph. We had 2 miles from start to finish line. I did remove rear spoiler pieces and front splitter side winglets to free up some drag. About 1\8 mile before finish line we actually hit 207mph but dropped 2mph by the finish line.

Lol. The nay sayers will never accept that the stock Zp6 can crest 200mph because..... they read on the internet that it can't..
They also read on the internet about how slow it is.
If you beat on it itll overheat..
Even a hyundai can kick its *** above 120...
Shall i go on?
I've been pretty high up in mph in mine woth stage III on and in full effect and rate of speed is relative..... the Z06 is pretty dam fast above 120 and is still pretty dam fast above 150..
Plenty of videos to back that up.
Sktck Z06 can do 200 if there's room. They sacrificed the top end for downforce in a cost effective way. It works. You get a lot more than what you pay for with this car. As you do with every model in the line up going to back to C5...
There will always be the haters..most are self hating and never happy no matter what.
Enjoy your mew Z06.. i know i will (again) when i trade my 16 for a 19 in a little more than a month once it's built.

Here is the link to the full PDR video in Sun Valley Idaho last year. To answer your question my car has an A8 trans.

At first I thought the video was sped up. But anyhow. That's awesome! Pretty stable too.
Likely that car has headers, upper and lower pulley and support mods. At that acceleration it's gotta be making 700+ whp

I have a car with a Corsa, had a car with a borla, and good friend has a borla. They don't sound like that. Borla actually makes the sound deeper. His sounds like an ARH setup.

A pair of headers isn't going to take a car from 185 to 207......
So either the car is heavily modded OR haters are misinformed.
Not sure which.

That doesn't sound right. And it's way too fast for a stock Z06 with just intake TB and xpipe.

This video is at Daytona with a passenger, both windows down and of course the banking. My car is a m7 and completely stock.

I have a 2015 Z06 with Z07, M7, and stage 3 aero.
At Arkansas Mile the first time car was stock, but I removed the rear wing down to stage 1 and removed the stage 3 winglets completely from the front. 178.5 MPH was my best run. Starting in first gear.
Year 2 I went back with LMR mods, now at 767RWHP, best speed starting from 2nd gear was 184.6, I know one would expect more improvement than that but just keep in mind that was starting in 2nd gear and there was a pretty strong head wind that day and the temps were in the 90’s. I think I only remember getting one run in on that Sunday before the rain came.
Unfortunately for the M7 you have to go to 5th gear and its .82, forget trying 6th (.68). With a 3.42 rear gear.
The A8 has an advantage in the standing mile with 6th gear being 1 to 1. (4th gear is 1 to 1 in the M7)
