Chip, we've been over this. But here's a refresher.
40 years ago (actually 39, in the fall of 1972), Tommy Ivo ran the first-ever 5 second run in Top Fuel. Probably running around 230-240 mph. Back when the shutdown was much shorter than 2011.
In 2011, the shutdown is longer. The brakes, parachutes, etc are better. But 150 mph S/R or 180 mph T/S-T/D can't stop?
