Not too shaby for an auto car that grandma can drive

I would be happy to race either of those '07 ZO6s heads up for ET. It's common for automatics to be 2-3mph slower in trap speed, but still get to the finish line first.

Last week Friday went to Great Lakes to try to validate the car's performance. Ran 10.47 @ 133.2 mph off of a 1.55 60 ft. Density altitude was about 700-800 ft - fairly good air. Very similar to the DA during the 1/2 mile shootout and very similar to the day from a year ago with the 10.44 @ 133 from US41.

I think it's safe to say the difference between the 159 mph in the 1/2 and the 133 mph in the 1/4 is about right since the weather was very spot on. 26 mph gain seems about right for the 441.

Kevin,

It seems that 25mph may be a good number for estimating 1/2mile based on 1/4 mile trap. As an example, Pete's 129 1/4mile goes ~ 154 1/2mile. That would suggest Al and BobG at about 159+. So it would be a GLORIOUS race between them and the Z06s.

The results for the Chicago 1/2 mile WANNAGOFAST event is posted on their web site. I took the liberty of beginning the compiling and sorting the raw data and a piece of that preliminary work will appear in the HOTB, perhaps yet this week.

Some pretty interesting stuff. I'm curious what some of us number-crunchers are going to glean from this event! I know Lance will be all over it, and I'm working on an article for next edition of the HOTB that will merge Marc Haibeck's piece on torque and acceleration with average torque under the curve (of the LT5s vs. others) and see how the race data compares.

Good stuff!!

I think you're math is on target, but as for a hypothetical between Bob G and the ZO6s that won the N/A class, I'd lay some cash on Bob G and not bat an eyelash. Bob's 1/4 trap is faster than my car by 2-3 mph and I know that shifting into overdrive with the automatic after mid-track hurt my mph a lot. My RPMs were only about 5800 when passing the 1/2 mile mark - way below power peak. With the 6-speed, that wouldn't be a problem for Bob. I predict he'd gain 27-28 mph in the 1/2 mile over the 1/4 and run about 162-163, and take the ZO6 comfortably.

At the risk of sounding like a spoil sport, I wish they had an ET clock out there. My first run was a 159.0 mph - went heads up against one of the shop tuner cars - entry #171 the Nissan 350Z Dynosty Twin Turbo who ran 165.5 mph. He was about 5 car lengths behind me. I think he thought he was going to win when he lined up against a poor old N/A C4 Vette.....
