    An e-mail from Bill Neely to David E. Davis, Jr.
    of Automobile Magazine…


    A lesson in acceleration but first some useful information:
    One Top Fuel Dragster 500 cubic inch Hemi engine makes
    more horsepower than the first 4 rows at the Daytona 500.
    Under full throttle, a Top Fuel Dragster engine consumes
    1.5 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 426 Hemi V8 engine cannot produce enough
    power to drive the dragster’s supercharger.
    With 3000 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 1.7:1 air/fuel mixture for nitro methane
    the flame front temperature measures 7050 degrees 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 half way, the engine is dieseling from compression
    plus the glow of exhaust valves at 1400 degrees F. The
    engine can only be shut down after cutting the fuel flow.
    If spark momentarily fails early in the run, unburned nitro
    builds up in the affected cylinder 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 at 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 mph 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.
    The red line is actually quite high at 9500 rpm.
    The Bottom Line; Assuming all the equipment is paid off,
    the crew worked for free, and for once NOTHING BLOWS UP,
    each run costs an estimated $1,000.00 per second. The current
    Top Fuel dragster elapsed time record is 4.441 seconds for the
    quarter mile. The top speed record is 333.00 mph 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
    Corvette Z06. More than a mile up the road, a Top Fuel
    dragster is staged and ready to launch down a measured
    quarter-mile as you pass. You have the advantage of a flying
    start. You run the Vette up through the gears and blast across
    the starting line and past 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, but you hear a brutal whine that sears your eardrums,
    and within three seconds, the dragster catches you and
    beats you to the finish line, a quarter-mile from where you
    just passed him. From a standing start, the dragster spotted
    you 200 mph and not only caught you but nearly blasted
    you off the road when he passed you within a mere 1320 feet.
    That, my friends, is acceleration!!
