maybe GM should publish the best customer 1/4 ETs they can find on the internet for all thier vehicles.
I think GM says 11.7 @ 125 for the Z06
So GM's published numbers are 5/10ths slower than what the car is actually capable of? What is the point of that? Shouldn't the published numbers indicate the peak capability, rather than just an average time? Not being contentious here, but that seems kind of silly.

I think I saw Ranger's 11.2 on street tires...
So when 99% of owners can't achieve the factory spec you think they are going to be happy?

I don't believe GM takes the same approach as the drag racing crew - they don't show up with 1/4 tank gas, change air pressure, cool the car for 1 hour, wait for a negative density altitude day, etc. I'm not even sure GM tests on a real drag strip or uses NHRA process of having two trap timers and averaging the last 60 feet (1260 feet to 1320 feet) to arrive at trap speeds. So in the end, I think the 11.7 factory spec is about right ET wise (real hard core guys will go lower as we have seen on a well prepped surface) and the 125 trap is probably a bit inflated (assuming they don't average 60 feet like the drag strips do). I'd imagine they take the trap of 125 right at the 1320 mark and thats going to be slightly inflated versus a real nhra run.
High 10's, meaning 10.9, trap around 130. 138 is a bit optimistic. If this car traps at 138, that indicates low, low 10's.
If the car weighs in 200 lbs more than the Z06 the HP to WGT isn't going to be that big a difference, about like adding 50 rwhp to the Z. I would guess a decent driver low 11's around 130 would be my guess? But there is more to it than that, as the extra weight might not allow the car to leave as good as the Z or the extra torque combined with the extra weight might make traction near impossible? Or maybe it will be a 10 sec rocket ship! I think that we will just have to wait and see when they come out.

When conducting performance tests do they account for the weight of the driver? One driver might weigh 200 lbs, another could weigh 150 lbs, hence a difference of 50 lbs for the car to deal with. Pardon my ignorance on such matters, but it seems it could make a small difference in test results.
It looks like there won't be any way to run the ZR1 at it's full potential at the dragstrip based on current sanctioning body rules. 11.49 and quicker requires roll bars! I guess you might get one full pass, then you'd be gone. NHRA is going to be VERY aware of what these cars will do, so they will be watching very closely I'm sure.
I know a guy who made a PVC roll bar for his C5 convetible with metal covering so magnet would stick and he never got questioned. Car ran just under 12.50 @ 112; However, 11 flat at 130 is a much bigger hit if something happens, so that's a real bad idea.

Not yet! I am guessing 11.2
