There are no rockets or airplanes built by any government in the world that can accelerate from a standing start as fast as a Top Fuel Dragster or Funny Car..and that includes any aircraft launched by a catapult from an aircraft carrier. Nothing can compare.. * +

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 (0.15) of a second for all 6,000+ horsepower (some believe 8,000 HP is more realistic - there are no dynomometers capable of measuring) of an NHRA Top Fuel dragster engine to reach the rear wheels. 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'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 mixtur * +

of nitromethane, the flame front temperature measures 7,050 deg F. (Oxy-acetylene on cut is 6,300) 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 one pass. After halfway, the engine is dieseling from compr * +

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 a 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 accelerati * +

before half-track, the launch acceleration approaches 8G's. Dragsters reach over 300 miles per hour before you have completed reading this sentence. The redline is actually quite high at 9,500 rpm. a55 uming 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 * +
