I just read this on another car forum:

If you think your car/old farm truck/bike is fast, THINK AGAIN! Top Fuel Dragsters are absolutly incredible.


* 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
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'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.

* 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 7,050 degrees F.

* 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 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 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 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
(09/28/03Doug 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 200mph 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 friends, is acceleration!

I didn't know if it had been posted here but knew that it has been around for a while though. It is a pretty interesting perspective on things as far as acceleration goes...

It is almost hard to imagine that if the Corvette is going 200MPH that the dragster would beat the Corvette to the end of the 1/4 mile without sitting down to figure that it takes the corvette 4.5 seconds to travel the 1/4 mile.

That is REALLY hard to believe about the flying 200 mph head start. Still interesting! :)

Everything about top fuel dragsters is phenomenal.

To give you some idea of how far dragsters have come along and how old I really am, when I started drag racing (about how many years ago was that?) the fastest dragsters top speed was only in the 120's (MPH).

So while there are a lot of miles on this olddawg dragsters have improved greatly!!!...haha...

If you read this before I edited it don't answer the question "about how many years ago was that?"

But what about a Supa traveling at 200mph??? J/K Last I read the average dragster has 6000hp and the first 800-1000 is used just to turn the supercharger.
