I'd like to know that too. My estimate (not that I am any good at estimating) is about 3,500' acceleration zone and about 1,500' braking zone.
I asked Wes by email. Stay tuned.
Edit: Wes responded that he thinks my estimate is ballpark. It's 3,000' to turn 1 and, it seems to me the flags were about 500' past the turn.
So...zero to 170+ mph in 2/3 mile and about 22 seconds by my video cam. Not too shabby for easy-on-the-clutch starts!
