>
> DEFINITION OF ACCELERATION
>     
> 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 of a second for all 6,000+ horsepower of an 
> NHRA Top Fuel dragster engine to reach the rear wheels. 
>
> 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. 
>
> 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: ethodology and technology by which 
> quantities of reactants and products in chemical reactions are 
> determined) 1.7:1 air/fuel mixture of 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 pass. After 
> halfway, The engine is dieseling from 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 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. 
>
> Assuming 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 is 336.15 mph as measured over the last 66' of the run 
> (05/25/05 Tony Schumacher, at Hebron , OH ). 
>
> 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 pass. You have 
> the advantage of a flying start. You run the 'Vette hard up through 
> the gears and blast across the starting line and pass 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 passes you. He 
> beats you to the finish line, a quarter mile away from where you just 
> passed 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 passed you within a mere 1,320 foot long race course. 
>
>         ...... and that my friend, is ACCELERATION!
