Interesting Drag Racing facts.....

  1. Found this on the Viper Club forums......

    * A Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower
    than the first 4 rows at the Daytona 500.

    * Under full throttle, a dragster engine consumes 1½ gallons of
    nitromethane 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 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 nitromethane the flame
    front temperature measures 7050 degrees F.

    * Nitromethane 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 1/2
    way, the engine is dieseling from compression plus the glow of exhaust
    valves at 1400 degrees 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 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 miles per hour before you have completed
    reading this sentence.

    * Top Fuel Engines turn approximately 540 revolutions from light to

    * Including the burnout, the engine must only survive 900 revolutions
    under load.

    * The redline is actually quite high at 9500 rpm.

    * The Bottom Line: Assuming all the equipment is paid for, the crew
    worked for free, and for once NOTHING BLOWS UP, each run costs an estimated
    US $1,000.00 per second.

    * The current Top Fuel dragster elapsed time record is 4.441 seconds for
    the quarter mile (10/05/03, Tony Schumacher).

    * The top speed record is 333.00 mph (533 km/h) as measured over the last
    66' of the run (09/28/03 Doug Kalitta).

    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 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 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 you,
    but nearly blasted you off the road when he passed you within a mere 1320
    foot long race course. That, folks, is acceleration.

  2. Well put, Anthony
  3. Thats awesome stuff, thanks!
  4. makes my car seem like crap : (
  5. 7050* F!!!!! Thats Hot!
  6. its got more hp in one cylinder than an entire nascar engine
