Charging down the course in low gear, Mickey
Thompson accelerates his machine up to 210 mph
before shifting to second gear. In second the car
goes to around 325 mph before the shift into high.
Planned maximum velocity is in the neighborhood of
425 mph. Mobil-blended nitro fuels bring the horse
power rating for each engine up to 510 hp.
