Faster than a speeding VW.

Older post but still interesting. And people thought their big trucks and Hummers got lousy fuel mileage.
Ever wonder why a Top Fuel d**gster gets a rebuilt engine after each run? - even if you aren't a 'car nut', this is interesting.
One Top Fuel d**gster outfitted with a 500 cubic-inch replica Dodge (actually Keith Black, etc) Hemi engine makes more horsepower (8,000 HP) than the first 4 rows of cars at NASCAR's Daytona 500.
Under full throttle, a d**gster engine will consume 11.2 gallons of nitro methane per second; a fully loaded Boeing 747 consumes jet fuel at the same rate but with 25% less energy being produced.
A stock Dodge Hemi V8 engine cannot produce enough power to even drive the D**gster'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 lockup at full throttle.
At the stoichio-metric 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, disassociated from atmospheric water vapor by the searing exhaust gases.
Dual magnetos supply 44 amps to each spark plug, which is typically the output of a small electric arc welder in each cylinder.
Spark plug electrodes are totally consumed during a pass. After 1/2 way thru the run, the engine is 'dieseling' from compression and the glow of the 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 enough force to blow the cylinder heads off the block in pieces or split the block in half!
D**gsters reach over 300 MPH + ... before you have completed reading this sentence.
In order to exceed 300 MPH in 4.5 seconds, a d**gster must accelerate an average of over 4 G's. In order to reach 200 MPH well before reaching half-track, at launch the 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 for, the pit crew is working for free, and NOTHING BLOWS UP, each run will cost 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)
6 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 D**gster accelerates quicker than any other land vehicle on Earth ...
Quicker than a jet fighter plane ...
Quicker than the space shuttle ...
Or snapping your fingers!
The current Top Fuel d**gster elapsed time record is 4.42 seconds for the quarter-mile (2004, Doug Kalitta). (I think the time is now closer to 4 seconds, as of Winter 2014.)
The top speed record is 337.58 MPH as measured over the last 66' of the run (2005, Tony Schumacher).
Update:
Only going 1000 feet (320 feet less than 1/4 mile) they do it in 3.7 seconds at around 332 mph with 10,000 horse power with 90% n itro - methane 10% alcohol.
THEY THOUGHT THEY WERE GOING TOO FAST FOR 1/4 MILE AND COULDN'T STOP.
Let's now put this all into perspective:
Imagine this: You're driving a new $140,000 Lingenfelter twin-turbo powered Corvette Z-06. Over a mile up the road, a Top Fuel d**gster 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, on up through the gears and blast across the starting line and pass the d**gster at an honest 200 MPH. The 'tree' goes green for both of you at that exact moment. The d**gster departs and starts after you. You keep your foot buried hard to the floor, and suddenly you hear an incredibly brutally screaming whine that sears and pummels your eardrums and within a mere 3 seconds the d**gster effortlessly 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 d**gster had spotted you 200 MPH. And it not only caught, but nearly blasted you off the planet when he passed you within a mere 1320 foot long race!
That, my friends is acceleration.

I have never understood the public's fascination with racing speed in vehicles of any kind, animals or human beings. :roll: However, at a point in time, I was fascinated with fast women. :mrgreen:

The only thing I would dispute is your statement that only does 900 revolutions during a run . At 9500 rpm for 3.7 seconds it's way past 900 rpm.

You may want to revisit your math on those numbers.

You, Sir, are fascinated with women period, but all in jest as you have your love of your life~~ :thumbup:

Yup, leave it to the master calculator of pricing and parts~~~ :lol: :lol: :thumbup:

And i h**e math....if ya live by the numbers, ya die by the numbers....stupid decimal points get you every time :-D
Have a good trip back did ya? TSA get a little handsy on ya? After 3 cookies i wouldn't care....may have even gotten a little handsy back....right before the beat down :shock: :-D

So was I many years ago my problem was not being fast enough to catch as many as i liked.

I don't know where some of these details came from either but 900 revs with a top out at 9500 revs per minute mathematically seems close but practicality wise makes no sense.

Ya think...We'd do better to arrive at airport naked and breeze right through those dang lines...Going, it was a lot quicker, even with high alert status, but Denver is crazy.....Take off your shoes, your belt, all liquids out, laptop out, phone even, go through oh danggggg a bracelet still on my wrist...Asked him I needed to remove my toe rings too..He smiled....Asked if I needed to remove under wire bra, he blushed. Called female TSA agt. over, she did her thing, very professional I might add..
Then wait two hrs for flight....Get on plane, ready to taxi out, delayyyyyyyyy, have to load some luggage missed from prior departure...45 minutes later, ok we're ready...Wait, 15 more minutes, now they were waiting on the paper work for the added baggage..Finally, up, up and aaaaaaaaaawayyyyy...
Arrive and waitttttttttttt for dang luggage almost hr. and half..By then this girl was at the baggage claim customer service with Manager and I called American Customer service too, got a supervisor gave em a bit of my mind and while talking out comes luggage......lolololooll
But all in all, it wasssss not a good flight..lololololol Have 3 emails from American, confirming my complaint, apology from them over delays and confirmation of the complaint code...lololol I had told them I was going to write in my blog how bad they were, and write every board member sitting on the board of directors starting with the President, down..Little do they know I will......lololololol
Could have used those cookiesssssss for sure... :mrgreen: :shock: Then I would have just been skippen around the airport singing "somewhereeeeeee over the rainbow skies are blueeeee"~~ :lol:

I hear ya...i h**e airports, i would rather drive my truck to the waters edge, put it on a boat and float it to where i'm going...i do like the man groping me though :shock: the trick is to hold eye contact with them and smile....and when they finish you say...thank you sir, may i have another...makes people in line chuckle, TSA not so much....dirty blue gloved bastards!!
That's why we drive to Bama, only takes an hour and half more.....but no airport bullcrap.
Next time throw down some cookies, and bring some special suckers for the ride.
Glad you made it....and give them hell on the wait...flying was fun at one time not long ago, use to walk right on with my rifles, and archery equip...and all the peanuts you could eat :-D

Wait, archery?? Whatcha' got?? I had a Kodiak Magnum..Loved it because it was a shorter length, easier for me to use and the wood was beautiful..........Only for sport never k**led a thing with it...Loved going out an practicing it tho~~ Snapped my arm a couple times when learning..That hurts!!!!!Teaches you real quick too....Long time ago..Miss it now.......
lololol on the man groping thing...When I have had that, its a women and they have always been professional.. I tease them like I wrote above and it sets the tempo~~
Flying WAS fun..NO more..Traveling as I do I use a 4 hr traveling time for driving..Soooooooo much nicer, my coffee, music etc and I'm there...
I really did eat two of those "cookies"..Greg took me a dispensary because I wanted to see it..Walk, in, inhale and your done...No smoking allowed, but just the scent of the place was WOOOOWWWWWW...Pot from the ceiling to the floor~~behind glass of course...Cookies, brownies, herbs infused with oils from the pot, all sorts of eatables..I was actually surprised by that...
Not like the head shops used to be...Regulated and strict laws govern its open status...Nothing sampled, nothing open in the store..They do use those sealable plastic bags or if an ounce it goes into a box..Sealed and put in paper bag...Closed too...
Anyway I think I looked like a tourist inside as the guy was funny with me...High as a kite I am sure he was~~~ :lol: :lol:
