        One top fuel dragster 500 cubic inch Hemi engine makes more
        horsepower than the first 4 rows of stock cars at the Daytona 500.

        It takes just 15/100ths of a second for all 6,000+
horsepower of an
        NHRA Top Fuel dragster engine to reach the rear wheels.

        Under full throttle, a dragster engine consumes 1-1/2
gallons of
        nitro methane per second; a fully loaded 747 consumes jet
        fuel at the same rate with 25% less energy being produced.

        A stock Dodge Hemi V8 engine cannot produce enough power
        to drive the dragster's supercharger.

        With 3,000 CFM of air being rammed in by the
supercharger
        on overdrive, the fuel mixture is compressed into a
near-solid
        form before ignition.

        Cylinders run on the verge of hydraulic lock at full throttle.

        At the stoichiometric (stoichiometry: methodology and
        technology by which quantities of reactants and products
in  
       
chemical reactions are determined) 1.7:1 air/fuel mixture of nitro
        methane, the flame front
temperature measures 7,050 deg F.
       
        Nitro methane burns yellow. The spectacular white flame
seen
        above the stacks at night is raw burning hydrogen,
dissociated
       
from atmospheric water vapor by the searing exhaust gases.

        Dual magnetos supply 44 amps to each spark plug. This
        is the output of an arc welder in each cylinder.

        Spark plug electrodes are totally consumed during a
        pass. After halfway through the pass, the engine is dieseling from
        compression,  plus the glow of exhaust valves at 1,400 deg F.
       
The engine can only be shut down by cutting the fuel flow.

        If spark momentarily fails early in the run, unburned
nitro
        builds up in the affected cylinders and then explodes with
        sufficient force to blow cylinder heads off the block in 
       
pieces or split the block in half.

        In order to exceed 300 mph in 4.5 seconds, dragsters
must
        accelerate an average of over 4G's In order to reach 200 mph
       
(well before half-track), the launch acceleration approaches 8G's.

        Dragsters reach over 300 miles per hour before you have
        completed reading this sentence.

        Top fuel engines turn approximately 540 revolutions
from
        light to light! Including the burnout, the engine must only survive
        900 revolutions under load. (race and burnout)

        The redline is actually quite high at 9,500 rpm.

        Assuming all the equipment is paid off, the crew worked
for free,
        and for once NOTHING BLOWS UP, each run costs an 
estimate
       
$1,000.00 per second.

        The current top fuel dragster elapsed time record is
        4.428 seconds for the quarter mile (11/12/06, Tony Schumacher, at
        Pomona , CA ). The top speed record is 336.15 mph as measured over the
        last 66' of the run (05/25/05 Tony Schumacher, at Hebron , OH ).

        Putting all of this into perspective:

        You are driving the average $140,000 Lingenfelter
        "twin-turbo" powered Corvette Z06. Over a mile up the road, a top fuel
        dragster is staged and ready to launch down a quarter mile strip as you
        pass. You have the advantage of a flying start. You run the 'Vette hard
        up through the gears and blast across the starting line and pass the
        dragster at an honest 200 mph. The "tree" goes green for both of you 
       
at that moment.

        The dragster launches and starts after you. You keep
        your foot down hard, but you hear an incredibly brutal whine that sears
        your eardrums and within 3 seconds, the dragster catches and passes you. 
       
He beats you to the finish 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 caught, but near ly blasted you off
        the road when he passed you within a mere 1,320 foot long race course.

        ... and that my friend, is ACCELERATION!
