[QUOTE="hmwave, post: 1352540, member: 10968"] First time I'd experienced the Top Fuel and Funny Cars close up. Fastest was the US Army Top Fuel at 4.64, 320mph. John Force won the Funny Car race at 4.90, 309mph. Man, those things are visceral! 4.6secs of pure hell unleashed, an estimated 8000HP ripping down the quarter. Your whole body vibrates as they go by. 0-100mph in 0.8s, 5G off the line, 7G when the chutes come out, 280mph in 700ft, and one gallon of nitromethane per second (at $30 a gallon) with a fuel pressure of 500psi. We stood in the pits behind a Top Fuel they'd just rebuilt and were running at idle. Fingers in ears all round. When they blipped the throttle my eyes hurt and the air around was electric. Can't wait for next year. :-) Here's some other stats meantime... One Top Fuel dragster's 500-cubic-inch Hemi engine makes more horsepower than the first four rows at the Daytona 500. A stock Dodge Hemi V-8 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 nitromethane, the flame front temperature is about 7000 degrees Fahrenheit. Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, separated from atmospheric water vapor by the searing heat of the 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 can be totally consumed during a single pass. After half-distance, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees Fahrenheit. The engine is shut down by cutting the fuel flow. If a spark plug fails early in the run, un-burned nitro can build up in the affected cylinder and explode with sufficient force to blow the cylinder head off in pieces or split the cylinder block in half. In order to exceed 300 mph in 4.5 seconds, dragsters must accelerate at an average of more than 4 g's. In order to reach 200 mph before half-distance, the launch acceleration approaches 8 g's. A Top Fuel dragster reaches more than 300 mph before you have completed reading this sentence. Assuming that all of the equipment is paid off, the crew works gratis, and nothing breaks, each run costs an estimated $1000 per second. The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter-mile (October 5, 2003, Tony Schumacher). The top-speed record is 333.25 mph as measured over the last 66 feet of the quarter-mile (November 9, 2003, Doug Kalitta). 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. [/QUOTE]
