    This is from a friend of mine that I ride 3 wheelers with. The funny car below is the one that he and his dad raced in the 80's.

    Heres our old racer..................... [​IMG]
    We used to run Top-fuel dragsters and alky funny cars in the pacific n.w and throughout the U.S.. Heres a shot from the 80's at P.I.R. We won the 64 funny car event at seattle twice. Too much fun. Heres a pic;

    Then I thought this was cool;

    Some interesting Top Fuel Dragster Facts. *
    One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. They have over half again as much horsepower in one cylinder as a Dodge Viper has in all ten. No one has ever successfully run one long enough on a dyno to get a horsepower reading; current estimates are right around 6,000 horsepower.

    * Under full throttle, a dragster engine consumes 1-1/2 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. The fuel pump alone requires more horsepower to turn than the average street car produces.

    * 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.

    * The 1.7:1 air/fuel mixture for nitromethane produces a flame front temperature measures 7050 degrees F.

    * Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, disassociated 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 the run, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by running the car out of fuel. There is no way to cut off the fuel; the engine stops only when it blows or the tank runs dry.

    * 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. To put this in perspective; a top fuel dragster, parked next to a Super Hornet on the steam catapult on the deck of an aircraft carrier, would be in the water and sinking before the Super Hornet was halfway down the deck.

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

    * Top Fuel Engines only turn approximately 540 revolutions from light to light!

    * Including the burnout, the engine must only survive 900 revolutions under load. They only survive about 80% of the time.

    * The redline 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 engine is entirely rebuilt every run, or every 900 revolutions. New pistons and rings, new rods, new rod bearings. Sometimes a new crank. The crew does this in about two hours between rounds.

    * 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).
