>* Top Fuel Engines turn approximately 540 revolutions from light to

>333.00 mph. (533 km/h) as measured over the last 66' of the run

>Putting all of this into perspective:
>You are driving the average $140,000 Lingenfelter "twin-turbo" powered

>and blast across the starting line and past the dragster at an honest 200

>The dragster launches and starts after you. You keep your foot down
>but you hear an incredibly brutal whine that sears your eardrums and within

>line, a quarter mile away from where you just passed him. Think about it,
>from a standing start, the dragster had spotted you 200 mph and not only

>That folks... is acceleration.
