Wow - great post indeed! Much appreciated.
The event I'm attending is actually a German car tuner challenge - my daily driver is a highly modified 2000 Audi S-4. With all-wheel traction & 480 HP, a lot of these cars get well into the 11's. But the organizers are begging me to bring the Cobra. I have no illusion that I'll put up world beating numbers (but you never know,) but I'm sure the violent launch of a Cobra is going to be a crowd pleaser.
As I've said, when I've done short burn-outs in the Beast, it can lurch all over the place & I lift for self-preservation. I didn't want to get up to the line, rev it to 3500 rpm & pirouette into a chain link fence. Sounds to me like a 1/4 mile launch is similar to the launch at my track events at the start - give it enough juice to keep hooked up and straight. Modulating the power will be tricky, but I have experience doing that - not just flooring it and holding on.
Thanks for the tips! I'll post results after the event on the 13th.
