But that alone isn't enough for me to say the whole thing is bogus.

Hi
When I go for a 10 (even a high 10) next year...with my Nitrous.....I am going to have to run at LEAST 650 hp..possibly over 700....
I am sorry but I just dont believe that video...not on 500 ish hp....
And before anyone asks...YES I do have the expertise to say that...I was a Top fuel crew chief for a lot of years...
p.s....If I had to guess...that video is what we call ...a "cut n shut" ...like when you buy 2 wrecked cars and weld them together in the middle...
All the best Brett

One on the reasons the Z06's have been such kick-*** cars is that both the C5 and C6 versions were literally tuned by running at the Nurburgring. BTW, the C5 Z06 did 7:56 there.

I interviewed an enginer at GM regarding this topic for a story I'm writing. The Z was completely stock down to the tires and alignment. If the story ends up not getting published then I'll post the quote here.... but for now, just rest assured it was stock.
Also C5 Z06 time is from inside Chevy, not outsider. To me it really doesn't matter if those times are 1, 2, 5 or even 10 seconds faster or slower than some other manufacurer times. Both are very fast none the less. Still it would be interesting to see what SportAuto and Horst von Saurma would do with it. His time would give more equal data point as he has tested so many different cars in there. We (I and maybe others) are worst as someone in Corvette forum points out as I rarely believe manufacturer data on its own without any independent proof. In my case it has nothing to do with Corvette not being equal to Porsche. Latest fast Porsche times were set with engine at wrong end. Corvette with its currect (perfect) configuration is more interesting to me than 996 and 997 variants. As von Saurma has done fast lap in Carrera GT he should be able to give similar results with Z06. I don't know if he has already done so. If he has, I have missed it. If not, why? Z06 has been available in Europe for a while already and I think it would be interesting to see what he can do with it. If he could repeat the time it would be good press for GM.

I've seen times for stock Z06's that vary from 11.7 to 12.2 depending mostly on how good of a launch they get on the street tires......considering an 11.7 run on street tires....then 10.85 is possible with a perfect run on slicks (& some removal of weight).....clearly the driver in the video is a skilled drag racer and knows what he's doing!

Up here there is a very well known 928 PCA racer who shares his car with his wife (an excellent driver in her own right). Their lap times differ by as much as 10 seconds on some weekends. No modifications to the car except the seat is moved forward a bit.
You can also compare all of the top car magazines – it is rare to find the exact same data for any car. Most magazines (and car test shows) will admit they do not “power shift” since it is not a “real world” way to drive.

Are you also questioning Porsche's stated Nurburgring lap time with their GT2 (7:43.x) because it came 'from inside' Porsche, and not from some independent source?
And with that reasoning, let's say there was an independent source reporting on both Chevy and Porsche's lap times, and then the next protest would be, 'yeah, but, but, ...they were paid off to say the car went that fast'! It'll never stop...

And besides, there's nobody in Europe who's too keen on 'just a Chevy' kicking German and Italian *** from one end of the 'Ring to the other.

Production vehicles have variation in every single part of the car, does anybody here think its random chance that essentially a perfect combo ended up with a really hot driver? Or that any average person has even a 1% chance of walking into a dealer and getting a car that would dyno within 5% of Rangers car?
OTOH I met a husband and wife team that walked into the Chevy dealer and bought a pair of Z06 a few years back and went out and raced competitively on a regional level.
Stock is whatever Chevy or Ford or Porsche decide they want to sell. Whats the point? Plenty of daily drivers will wipe the floor with ANY stock vehicle. Thats why racing has classes, to make it a driver competition, not just a wallet competition. Not that wallet competition ever gets far behind.

Read what Ranger posted, launching at 3650, running right one the edge of what would blow the clutch, this is a guy that is getting 99.9% out of the car, a GREAT and lucky driver.
1.5 sec variation on a drag strip with an automatic must have had some real talent behind the wheel. Chalk talk before the race something like, green means push the right pedal all the way down. 1.5 sec is what you get maybe if you include runs that have large driver mistakes, smoking the tires, lifting the gas when the car gets squirrelly, getting a call on your cell and missing the green, that sort of mistake. Normal variation on best run is a lot smaller, and normal variation between good drivers is smaller still.
OTOH with a high power car, PLENTY of amateur drivers can't or won't powershift. It does tend to break your toys.
Road course is a different matter since driver style can be more suited to one course over another, and not many drivers could put a car very close to the edge for a full race. Errors compound, tires get out of the optimal temperature range, something knocks you out of the rhythm and you have to work back towards the edge.
Foo, all this thread has done is make me want to go racing, and I don't care if it was in a Camry.

Just so you guys know, the guy who made those 10.85 runs is WELL known in the vette community as an incredibly good driver. He currently holds the record for fastest times run in a stock C5 and stock C6 both with and without drag radials.

When publishing those numbers, each company will have their best pilot at the wheel; why would they not?
