So you think you\'re fast?

Just thought that I would pass this on to my pals in the Sportbike world. We know that we're fast, and can blow the doors off of just about anything. I've wasted vettes, destroyed vipors and made porsche owner's cry - we we're not as fast as we think we are.

A lesson in acceleration:
------------------------------------
First, some useful info:


One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500.

Under full throttle, a Top Fuel dragster engine consumes 4 liters 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 426 Hemi V8 engine cannot produce enough power to 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.

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 while traveling a quarter of a mile! Including the burnout the engine must only survive about 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
$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 riding the average $250,000
Honda MotoGP bike. 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 RC211V hard up through the gears
and blast across the starting line and past the dragster at an honest 200
mph (293 ft/sec). The 'tree' goes green for both of you at that moment. The
dragster launches and starts after you.You keep your wrist cranked 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.

That, folks, is acceleration

I've read that before but couldn't find it again. Thanks. That is crazy sh*t to think about. I can't believe the engine only see 900 revolutions in its life. Thats CRAZY!!!

Re: So you think your fast?

One of the loudest experiences in your life is to be right at the starting line when two top fuelers launch!!!! The sound waves blow your hair back. If you are unlucky enough to not have hearing protection... it is indescribeable.

Re: So you think your fast?

I used to live 5 miles from Indianapolis Raceway Park and even at that distance those top fuel dragsters and funny cars are flippin loud. and then i was only 8 miles from the Indianapolis 500 and THOSE cars are loud. Top fuel is bad but i'll stick to my sportbike and pro street 'stang thank you :grin:

Dragsters are nice and all...But I can't pick up the latest top of the line dragster for $11,000 from my local dealer. Or take it to work everyday and get the best parking spots. :smile:

Re: So you think your fast?

top fuel is the [censored] but for us average kinda guys, go for the streetable funny cars. I have a '66 chevy truck I have been restoring. Really fun because its not so overboard that I can't drive it to work but it can blow the doors off mustangs(...umm, not the shelby's though :frown: ) and other fast cars. I love seeing some pepper haired lawyer in his bmw thinking he is fast and then smoking him.

But you know, you would think that other guys in trucks of whatever would be the ones to try and race me but I swear, if I pull up to a light and a mini-van mom stops next to me, they ALWAYS try and race me then cut into my lane.

I mean, damn, its like you NEED a drag car just so you don't get mommy cutting you off.

:808918-ot:

Speaking of mini-van moms, a black one almost killed me the other night. I really need to get some marbles for windshields! ...or maybe roofing nails for the road. So far I have only had a minor close call with ONE male driver. All other close calls have been women. And most have been black. It would be such bullshit to die by the hands of a min-van mom who hates you....We deserve better!

Seeing the fuel cars in person is something everyone should add to their life's to-do list. It's an awesome display of power. :Wow1:


I once heard someone say that we could prevent a lot of military conflicts by taking a fuel car on a world tour. Let them watch it make a few passes. Let them consider this is what we do for fun. Let the implications sink in for a few minutes. :wink:

That commercial kills me... the guy on the bike has the CHEAPEST Harley POS you can buy, and acts like he has the right to look down on the guy with the dinette.
Tell you the truth, I'd get a nice dinette before I got a Sportster :lol:
Actually, I'd get a nice used R1 before I got either :waytogo:
