427 Convertible 1/4 mile times?

Racer aren't verts banned from tracks w/out a roll bar? Also I agree in that most vert owners want a nice cruiser with a little umph under the hood, even the GS vert is very adequate.

12.0-12.5 is not great, considering some members are calling this a Z06 convertible. 200lbs is 2 tenths, with this thinking the car should be able to pull an 11.2- 11.4 with the right driver. Don't think so. I think with its extra power, if a driver can't launch it without spinning the tires on the street, it could lose some races against the Grand Sport, which won't spin off the line as bad.
As far as losing to a LS3....the 427 better spin a lot. We have all seen someone light up the tires at the lights, and it will loose a race without a problem, tho.

DITTO.
Speaking of Grand Sports (2010) the coupe weighs more than the GS vert from the info I have seen. It's about the heaviest vette out there with an A6.
Oh, and I have had no problem "Kicking A$$" on even "modified" supercharged Cadillacs & ZL1 Cameros at the track lately and I'm still running on run flats, this stuff makes my day.
PS: The last time I went to the track I still pulled off an 11.57 using new replacement "Bridgestone" runflats that weigh approx. 2 lbs. more per tire than the original OEM Goodyears.

I am thinking that the owners of these cars are not the same type of owner that would own a Z06 or ZR1 as their sole Corvette. I think they are more not into the speed but maybe more show than go, with the ability to press that loud pedal once or twice to scare the crap out of themselves.

Maybe another reason we do not see too many of these on the strip.
This is NHRA regs for 2009, not sure of current regs but this has probably not changed.
11.49 1/4-mile (7.35 1/8-mile) or quicker:
-A 5-point minimum roll bar on a fixed roof car (t-tops okay as well if in place while racing) from 11.49 to 11.00 (7.00 1/8-mile). If the hardtop / t-top car has un-altered floors, firewall and frame rails (wheel tubs are okay), then the 5-point roll bar is good til 10.00 1/4 mile (6.40 1/8-mile). Convertibles require the 5-point bar from 13.49 (8.25 1/8-mile to 11.00 (7.00 1/8-mile).
The rollbar must be constructed of a minimum o.d. mild steel or chrome moly tubing (moly can be a smaller o.d and is lighter but more expensive), see diagram below for specs.
The roll bar can be bolted or welded to the floor, see diagram below for specs.
Roll bar must be padded anywhere the driver's helmet may contact it while in the driving position, see diagram below for specs.
The 5-points are:
Main hoop; 2 "down bars" (bars that go from the main hoop rearward to the trunk floor/hatch area. These can be straight or bent like a "package tray" style, search for photos); Welded crossbar for belts (can't be removable), see rulebook for exact location. Driver side door bar (can be a swing-out. Many put a passenger's side bar in as well (6-point) because it strengthens the car on both sides, but if you have subframe connectors the difference may be minimal).

I know that I for one wont be taking mine down the quarter mile. Those days are in the past for me. Our local track requires too much safety gear for me to even attempt it in a vert. Mine is a fun car, and will be driven fairly hard on warm dry ground, right up until I start to exceed posted limits, lol, or otherwsie when no one is looking or around.
I suspect that many of the owners are of the same mindset, whereby its a cruiser, and would likely only see qurter mile tracks from the parking lot. In order to get one of these to run good quarter mile times would require a good driver, nice hot tires, and the whimsy to approach redline to get on down the track in a manner that would make the onlookers proud. I think many of the guys wont be doing that anytime soon, especially those of us that would have ot install rollbars, harnesses, etc to do so.
I would think that the track minded folks would likely have steered away from the 427 vert for those reasons alone.

What is this Camero you speak of?
Just bustin' your chops, bud.
I have been to a track like that. My friends 98 WS6 A4 vert ran faster than the 13.49 and they told him he was done....and he was stock!
It would be cool to see someone take it down the track.
Though most wont I dont hold anything against them for not taking it down the track. Me, I would have to. lol

If I could get a run down a track without all of the safety requirements, I would give it a go, its just too restrictive these days, but obviously with good reason. For me, its just a fun car, that "may" hit quarter mile speeds every now and again when no eyes are on it, but there wont be a christmas tree or timer....

Thanks for letting me know, I really hate spelling errors. I don't know about you but it makes me feel like an IDIOT, English/spelling was my "worser" subject.
Now the story behind "Camero".
I can not tell a lie! I had it spelled with an "A" but I double checked with my significant other who owned a "Camero" and is usually a much better speller than I am. Well, she was wrong!!! and I told her so?

Or GM uses <160 lb. professional test drivers for the 1/4 mile.

For her being wrong you should something "special" from her. lol
Real World Times= My 2010 Grand Sport A6 Coupe best "stock" 1/4 mile time is 12.31 @ 115.75 mph and I hold the "Total Stock" GS record for a while now and the next to me is over two tenths slower, and I weigh 260 lbs so my car or me must be an "odd ball" to be that quick.

I bought my 427 because I had wanted GM to build a convertable Z06 since they came out. I know, I know, it's not a convertable Z06, but let's say it is as close as we are going to get. I would love to be able to take it to a track somewhere just for peace of mind that no speed limits to break and no cars coming the other direction around the next turn. I know that isn't going to happen so I'll press the pedal very carefully in what I consider safe conditions when I get the opportunity. That said, I want the prestige of having a bad iconic motor under the hood and just knowing that baby is in there is enough for me. For those wanting Youtube proof of this car's ability, here is a couple of links to reviews that are not GM connected. I think this shows this car's performance ability quite clearly and I consider it pretty impressive.

3404 lbs. curb wt. is what the second video (Ignition) has the 427 vert listed as, not 3475 so it comes down to who you want to believe. If I had one I would use GM specs or weigh it on a good scale myself.

Car and Driver's tests - 3421 for the 427, 3261 for the last Z06 they tested (had the Z07 stuff).
GM's figures probably don't include a tank of gas, and AFAICT they aren't trim-level specific.
