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.

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: methodology and technology by which quantities of reactants and products in chemical reactions are determined) 1.7:1 air/fuel mixture for 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 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 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 (09/28/03 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, all within a mere 1,320 foot long race course.

.....and that my friends, is ACCELERATION!

Lets see one of y'all try and compete against that with your Rice xd

Now that was quite interesting to read. I need to put this in my sig...
Dragsters reach over 300 miles per hour before you have completed reading this sentence.

Thats great. I might have to stickey that for a while. Thanks for the info!

eek eek eek eek eek Can I pick my jaw up off the floor now? eek eek eek eek eek

I'd like to see you guys make that thing turn faster than 5 mph without crashing xd

Well in all honesty I would much rather go very fast in a straight line then turn. Maybe because I'm amreican? Not sure. Don't get me wrong tho, I would rather race SCCA then NHRA, but in the street, it's all about the drag race.

That's what I call settin' the night on fire... twisted

Let's get this back on the front page where it belongs wink
