S2KI Honda S2000 Forums - Trivia for the 1/4 mile fans (This was emailed to me)

Wow! This is some impressive trivia...

Acceleration

For you guy's that like speed and power

-----------------------------------
* 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 1O 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 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 1/2 way, the
engine is dieseling from compression plus the glow of exhaust valves at

1400 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 at 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 red-line is actually quite high at 9500 rpm.

* The Bottom Line; Assuming all the equipment is paid off, the crew worked for
free, and for once NOTHING BLOWS UP, each run costs an estimated US $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 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 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 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 1320 foot long race course.

That, folks, is acceleration.
