ACCELERATION PUT INTO PERSPECTIVE

* One Top Fuel dragster 500 cubic-inch Hemi engine makes more horsepower (8,000 HP) than the first 4 rows of cars at the Daytona 500.

* Under full throttle, a dragster engine consumes 11.2 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 merely drive the dragster's 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 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.

* Top Fuel Dragsters are capable of reaching well over 300 MPH before you have completed reading this sentence.

* In order to exceed 300 MPH in 4.5 seconds, the dragsters must accelerate an average of over 4 G's. In order to reach 200 MPH well before half-track, the launch acceleration approaches 8 G's.

* 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 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 $1,000 per second.

* 0 to 100 MPH in .8 seconds (the first 60 feet of the run)
0 to 200 MPH in 2.2 seconds (the first 350 feet of the run)
8 g-forces at the starting line (nothing accelerates faster on land)
6 negative g-forces upon deployment of twin ‘chutes at 300 MPH

* An NHRA Top Fuel Dragster accelerates quicker than any other land vehicle on earth. Quicker than a jet fighter plane. Quicker than the space shuttle.

* The current Top Fuel Dragster elapsed time record is 4.420 seconds for the quarter-mile (2004, Doug Kalitta). The top speed record is 337.58 MPH as measured over the last 66' of the run (2005, Tony Schumacher).

Putting this all into perspective:

You are driving the average $1,500,000 Bugatti Veyron. A few miles 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 Veyron hard up through the gears and blast across the starting line and past the dragster at an honest 250 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 250 MPH and not only caught, but nearly blasted you off the road when he passed you within a mere 1320 foot long race!

That's acceleration !

A 60ft of 0.8 seconds at 100mph??...... psssshh, it ain't got nothing on the srt8 lol. I can't imagine my MIG welder putting out the power needed for 2 spark plugs, just insane.

I would like to experience that kind of acceleration. I wonder if there is an amusement park with a ride that is close to that. So far, haven't found one, but some of the roller coasters I've been on have been lots of fun! :)

The Top Thrill Dragster in northern Ohio does, I think. 0-120mph in bout 4sec, then 400 something feet straight down. Its a helluva rush but still doesn't even touch a real top fuel dragster.

Agreed, fun to be reminded of though and thanks to the OP for that. An indication of how old the news, it still relates everything to the 1/4 mile instead of 1000'. One of the tidbits of info that I didn't see in the list above that has always astounded me was the down force of the headers is 800 ft lbs! A great way to keep the wheels on the ground and give them some extra bite without adding any more weight the engine needs to overcome. Another thing that is pretty cool is their cooling system...

They are awesome bits of kit and do not get the credit they deserve, over here anyway.

I think one of the other facts that always astounds me, is that when on a full pass, by the time the rear wheels cross the starting line, it is already doing 100MPH+. Stunning.

If anyone has never gone to watch the Top Fuel dragsters and Funny Cars in person, I highly recommend it. I have been, and it is amazing to watch and hear them fly down the track. The sound literally shakes you as they roar by. Another cool thing is the flaming rooster tails you see coming out the headers if you watch them when it is dark outside. I recommend that you bring some hearing protection or you will be using your hands A LOT to cover your ears! In a pinch I suppose you could plug your ears with some bubble gum :)

Pfft, all these punk kids rolling around with sound systems are deaf anyways.

You're right though - night is the time to go, when they are just showing. The flames light up the sky - it's testosterone-based beauty.

I agree.. if you've never seen them run, go ASAP! Try to get about 1/3 down the strip and sit in the 1st row...

Another fun fact is that when two top fuelers leave the line at the same time they generate up to 3.9 on the richter scale!!! (measured at the track) :wink1:

We sit even with the starting line 20 rows up and this is what is soooooo good:

going to be about my 20th year at the Brainerd Zoo in August! :arms:
