a lesson in acceleration
something to while away a couple of minutes
A LESSON IN ACCELERATION-
*One top fuel dragster 500 cubic inch hemi engine makes more horsepower than the first 4 rows at the Indy 500.
*under full throttle, a top fuel dragster engine consumes I gallon of nitromethane
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 dragsters supercharger.
*with 3000cfm of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near –solid form before ignition. the cylinders run on the verge of hydraulic lock at full throttle.
*at the stoichiometric1.7:1 air/fuel mixture for nitromethane the flame front temperature measures 7050degrees F, 3800degrees C.
*nitromethane burns yellow, the spectacular white flame seen above the stacks at night is raw burning hydrogen, disassociated 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 ½ way, the engine is dieseling from compression plus the glow of exhaust valves at 1400degrees F.the engine can only be shut down by cutting of the fuel flow.
*if momentarily fails early in the run ,unburned nitro builds up in the affected cylinders and then explodes with sufficient force to blow the cylinder heads off the block in pieces or split the block in half.
*in order to exceed 300 in 4.5 seconds dragsters must accelerate at an average of over 4G`s.in order to reach 200mph 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 540 revolutions from light to light!
*including the burnout the engine must only survive 900 revolutions under load.
*the red line is actually quite high at 9500rpm
*the bottom line; assuming all the equipment is paid off, the crew work for free, and for once NOTHING BLOWS UP, each run costs an estimated $1000.00 per second. the current top fuel dragster elapsed time record is 4.441 seconds for the quarter mile (05/10/03,tony Schumacher).the top speed record is 333.00mph(533km/h) as measured over the last 66` of the run,(28/9/03 doug kallita).
If that hasn’t made you think enough, let’s put all this into perspective:
You are riding the average $250,000 Honda motogp bike- a seriously fast machine. Over a mile up the road, a top fuel dragster is staged and ready to launch down a ¼ 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 200mph (293ft/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 incredible 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 the standing start ,the dragster had a 200mph disadvantage, and not only caught ,but nearly blasted you off the road when he passed you within a mere 1320 foot long drag strip.

well written and fascinating - dragters are utterly brutal - the sound, the smell and the resonance within your lungs utterly (to quote the Docter) - FANTASTIC!

Another oft seen SIAL is the infamous STI quad bike. If I got a pound for every time that has ben on here I could have retired by now.
BTW if you do a search someone came up with a list of all the acronyms used here eg LOL, BTW, IMHO, etc. Hope this helps (HTH).
