    started a topic damm quick

    damm quick

    got this on an e-mail an thought it fairly interesting. :shock:


    A lesson in acceleration
    * 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 11.2 gallons (51 litres)
    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 ( 3900 degrees C ).
    * Nitromethane burns yellow. The spectacular white flame seen above
    the stacks at night is raw burning hydrogen, dissociated from
    atmospheric water vapour 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 RPM's from light to light!

    This one confused Stan, but stop & ponder the fact that the engine is
    only used for apx 4 to 5 seconds.
    * 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 10/05/03, Tony
    Shumacher). 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 riding the average $250,000 Honda MotoGP bike. 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 RC211V hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph (293 ft/sec). The tree' goes green for both of you at that moment. The dragster launches and starts after you. You keep your wrist cranked 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 nearly blasted you off the
    road when he passed you within a mere 1320 foot long race course.

    That, folks, is acceleration.
Working...
