I've heard some of the older racers talk about running on 1000' tracks. I didn't know there were any still around.
Anyway, one of my time slips from Bowling Green shows a 9.87 at 1000' on an 11.86@113mph quarter mile.
One car might run the quarter at 12.00@110mph where another car might run 12.00@130mph. It depends on the cars displacement, hp, torque, gearing, weight, traction, etc.
There are calculators that I've seen to calculate 1/8th to 1/4 and hp and torque based on mph and et but haven't seen anything that uses 1000' as a mark to calculate from.
