some really cool top fuel facts.

WAVEBYE · January 21st, 2007, 03:30 PM

found this pretty damn amazing. enjoy!

60' 0.852
660' 3.148 (probably low to mid 270 range - they didn't say)
1000' 3.961
1320' 4.678 @ 308.92 (low mph - Hillary went 4.673 @ 317.49)

One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the NASCAR 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 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 nitro methane the flame front temperature measures 7050 degrees 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 one pass. After half-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 4.440 seconds for the quarter mile (10/01/05, Tony Schumacher) The top speed record is 336.15 mph as measured over the last 66' of the run (05/25/05, Schumacher).

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.

seems like they should have more rpm's.

my go-kart has more

one more fact that i didnt see up there:

they only run about 4-6 psi in their rear monsters. witch is also less than my go-kart...

Drgnracin72 · January 22nd, 2007, 04:42 AM

those are some amazing facts. amazing what those cars can do

If I race a top fuel car for 10 miles would I beat him on my kids gas scooter?

MSTGGT00 · January 22nd, 2007, 07:42 AM

I had fun reading that.

i'd almost pay to see that

Sheesuz that makes my head hurty.I guess I won't be challenging any of those bad boys to a go against my specially trained racing goat:

What? You're saying they run 4-6 psi on their engine?

Drgnracin72 · January 23rd, 2007, 12:50 AM

no on their slicks

I was telling me dad about how a top fuel dragster could beat a Corvette going 200mph in the 1/4. He was if was not so. I did the math and the vette's time would be 4.5, so the drag car would beat it.
