Definition of Acceleration.
* One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows of NASCARS at the Daytona 500. * Under full throttle, a dragster engine consumes 1-1/2 gallons 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 Hemi V8 engine cannot produce enough power to drive the dragster's supercharger. (note: would that be the current "hemi" V8 or the REAL hemi V8 - 426 cubic inch that Chrysler offered in the 60's ? The REAL one put out over 500 HP and ??? torque with 2 four barrel carbs on gasoline !) * 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 mixture for nitro methane, the flame front temperature measures 7,050 deg F. * 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 a pa$$. After halfway, the engine is dieseling from compression, plus the glow of exhaust valves at 1,400 degrees F. The engine can only be shut down by cutting the fuel flow. * If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow cylinder heads off the block in pieces or split the block in half. * In order to exceed 300 mph in 4.5 seconds, dragsters must accelerate an average of over 4G's. In order to reach 200 mph (well before half-track), the launch acceleration approaches 8G's. * Dragsters reach over 300 miles per hour before you have completed reading this sentence. * Top Fuel engines turn approximately 540 revolutions from light to light! * Including the burnout, the engine must only survive 900 revolutions under load. * The redline is actually quite high at 9,500 rpm. * a$$uming 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 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 pa$$. You have the advantage of a flying start. You run the 'Vette hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph. The 'tree' goes green for both of you at that moment. The dragster launches and starts after you. You keep your foot down hard, but you hear an incredibly brutal whine that sears your eardrums and within 3 seconds, the dragster catches and pa$$es you. He beats you to the finish line, a quarter mile away from where you just pa$$ed him. Think about it, from a standing start, the dragster had spotted you 200 mph and not only caught, but nearly blasted you off the road when he pa$$ed you within a mere 1,320 foot long race course. ... and that my friend, is ACCELERATION! ------------- - waterdog - http://www.correctcraftfan.com/diaries/details.asp?ID=3896&sort=&pagenum=2&yrstart=1978&yrend=1978" rel="nofollow - 78 Ski Tique |

| I always thought that a Top Fueler was fast and you have explained it extremely well. After I saw my first Space Shuttle launch, a Top Fueler is nothing. How about 0 to 17,500 MPH in less than ten minutes!!! And capable of a top speed of 22,500 MPH. That's also not horizontal, but vertical and running well into 1 million +HP. The acsent into orbit burns approximately 10,000 lbs. of fuel/sec. I think the Top Fueler might still beat the Shuttle off the line, but the Top Fueler wouldn't have time to hear the whine of an engine going past him before he got vaporized by the exhaust. That, my friend is FAST. |

Motor Trend pubished http://www.motortrend.com/roadtests/wagon/112_0509_performance_wagons/street_racing.html - this article not too long ago comparing the original 426 to the new 6.1 Hemi available in the SRT Chryslers. The 425 hp rating (net) on the new motor matches the 425 published gross rating of the original (reportedly closer to 470). Not bad for a ULEV motor. ------------- |

Waterdog,
A friend of mine hangs with the "Plumb Crazy" drag boat team which is the current world record holder for the quarter mile. I believe it is 258 mph. He tells me the boat has over 7000 HP and burns 8 gallons of fuel in a quarter mile. I've seen videos, and when the driver gets on the throttle from a standstill, he lifts the entire boat out of the water. Quite the site. BKH ------------- Livin' the Dream |
