The definition of acceleration. I don't know where it originally came
from but it is impressive.
The definition of acceleration.
* One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower
than the first 4 rows at the Daytona 500.
* 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 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 (stoichiometry: methodology and technology by
which quantities of reactants and products in chemical reactions are
determined) 1.7:1 air/fuel mixture for nitromethane the flame front
temperature measures 7050 degrees F.
* Nitromethane 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

As little as I like drag racing in general...you have to hand it to these guys for creating machinery that is at the absolute pinnacle of the sport. the numbers are downright incedible, particularly the example of the corvette. Thanks for sharing.

Yes, the example is flawed.
The dragster might be doing 0-200mph in 3 seconds, but that doesn't mean that it will catch up to the vette that was pulling away from it during those 3 seconds at an average rate of 100mph.
In fact, it will take 3 seconds for the vette to STOP PULLING on the dragster, which will still be quite a way behind (about 450 feet).
Actually, the vette would probably win the 1/4 mile race as was presented above. The vette starts with 200mph, but assuming it has some power left, it will continue accelerating throughout the race.
The vette would ONLY need to trap at 206mph (for an average speed of 203 mph throughout the race) at the finish line to beat the world-record dragster in the above scenario.

I'm pretty sure the 'Vette would actually pull out a win. Assuming of course that it is this Lingenfelter: http://www.lingenfelter.com/pac725ttls1y.asp
1997-2004 Corvette Twin Turbo LS1, ZO6
427 CID 725 BHP / 650 lbs-ft of torque
0-60 MPH 3.2 seconds with street tires
1/4 mile 9.50 @ 145 MPH with street tires
Estimated top speed 230+
This bad boy would definitely have some steam left over the last quarter.
Although, I think the key to the logic in the sample was a previous statement that the dragster gets to 200mph well before half track. So, it has accelerated from a dead stop to 200mph in less than 1/8 mile (660ft). We would need to calculate the time it takes to exceed 200mph and start closing the gap to accurately determine the position of the 'Vette when the gap begins deteriorating.
The average speed for the dragster across the entire quarter mile is 297fps. Obviously it isn't traveling that fast in the first 1/8th. So, the sample holds up only if the 'Vette cannot accelerate beyound 200mph and covers the quarter at 293fps.
But it would be a much closer race than the sample leads you to believe.
