Top Fuel Dragster Fuel Pump Demo single cylinder

1st at idle, then full throttle... remember this is for only 1 cylinder, they have 8












Some interesting facts about Top Fuel Drag Racing!:

-One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. They have over half again as much horsepower in one cylinder as a Dodge Viper has in all ten. No one has ever successfully run one long enough on a dyno to get a horsepower reading. Current estimates are right around 6,000 horsepower.

-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. The fuel pump alone requires more horsepower to turn than the average street car produces.

-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.

-The 1.7:1 air/fuel mixture for nitro methane produces a 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, disassociated from atmospheric water vapour 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 the run, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by running the car out of fuel. There is no way to cut off the fuel; the engine stops only when it blows or the tank runs dry.

-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. To put this in perspective; a top fuel dragster, parked next to a Super Hornet on the steam catapult on the deck of an aircraft carrier, would be in the water and sinking before the Super Hornet was halfway down the deck.

-Dragsters reach over 300 miles per hour before you have completed reading this sentence.

-Top Fuel Engines only turn approximately 540 revolutions from light to light!

-Including the burnout, the engine must only survive 900 revolutions under load. They only survive about 80% of the time.

-Redline at 9500 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 engine is entirely rebuilt every run, or every 900 revolutions. New pistons and rings, new rods, new rod bearings. Sometimes a new crank. The crew does this in about two hours between rounds.

-The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile. The top speed record is 333.00 mph (533 km/h) as measured over the last 66' of the run.

-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.

Love this write up and video. I've seen both before, but they never get old.
If you're a gear head and you've never experienced NHRA fuel card in person, make it happen. It's a mind-bending spectacle.

I’ve only been once since the fuelers stopped running the quarter mile but they still make the ground shake. The numbers in that article are a tad outdated. HP has risen and the e.t.s have lowered.

That was an awesome read! Wish I could “like it” more than once.!

The backend of that car just crumbled! Wonder if they ever figured out what exactly caused it.
Eddie said his wing failed and still under power, over 300 mph the forces caused the frame to bind and collapse in front of him. Watching it was really scary. Ercie, his wife went to the hospital with him and before the finals, returned (with him)! He had a back up car but hadn’t qualified with it so he couldn’t run in competition. His Pennzoil dragster is mounted on the wall inside his ‘Fun Cycles’ dealership in Wichita Falls TX. Here’s a Buck knife he gave me and some pics of his garage at home. He was an Ariel

Good post. I have seen 2 shuttle launches from across the lagoon at the Cape. A top fuel cars roaring off the line is actually more violent and pretty dam amazing. My first time watching it a buddy said cover your ears. Being a man I didn't and it was partly the noise but the entire area around the track goes negative as the cars suck so much air and your ears pop like you have never felt them pop.

I still don't see how a human can survive these kinds of forces. Just amazing.

Eddie Hill certainly a legend.... Good stuff, this thread has me smelling sweet ole race fuel, funny but my youngest daughter always wanted to tag along and follow me around at the track, race fumes is still her favorite smell to this day lol.

Lots of fast girls out there bro on 2 and 4 wheels.
My youngest daughter has been going to the dragstrip literally since before she was born. She's definitely a gearhead, she loves the speed and noise. She has yet to express interest in her own car, but I'd say it's not long off. She's gonna be 10 in March.
