Some more little trivia:
If nothing goes wrong, and you have a perfect pass, and don't break anything, a top fueler will require $4500 in parts after a pass and it will have gone through about 17 gallons of fuel.

It's probably more like 1500HP. BTW, the displacement of the BMW he's talking about is 1.5L.

wrong again. I believe they are actually around 4000HP.

Meh, the Top Fuel dragster motor doesn't impress me. It's useless technology on the road and about the equivalent of a Saturn V rocket.

Then again, I always thought that Top Fuel racing was pointless anyway;)

At least we actually get something out of F1 engines/technology. Where do you think that the design basis for BMW upcoming V10 for the M5/M6 came from? :D

I figured you would appreciate the sheer insanity of 8000 horsepower.

I saw a show on Speed Channel or something where they had a segment showing the testing of fuel pumps for a funny car. At idle the fuel stream into the cylinder looked like it was from a garden hose. At wide-open-throttle it looked like a fire hose! Figure 17 gallons in 5 seconds, that's a pretty good flow rate.

Another interesting thing is that the blower takes over 400 hp to drive. That's pumping a LOT of air.

And TWO magnetos EACH pushing 44 amps :Q:Q:Q:Q:Q

F1 is all smarty-pants technology. Top fuel is a BIG F@CKING HAMMER. Both are interesting in their own way.

I love F1.... In fact, most of the engines in the maximum category are impressive. This season has been closest competition in years..... both pilot and team championships are within a few points.

Who is your favorite?

The blowers require 800 HP to run ;)

Kenny Bernstien goes through $80,000 worth of titanium valve springs each season.


Top Fuel Engines turn ONLY 540 revolutions from light to light!

The math does not work out, Max RPM = 9,500 divided by sixty = 158.3333 times 4.5 seconds = 712.499 revolutions.

Nope, you are about 15 years behind the times. These engines are naturally aspirated V-10s at 3 liters. The engines you are talking about were turbo 4 cylinder 1.5 engines that were run in the eighties but were banned long ago. Interestingly enough many of the 4 cylinder engines weren't much dfferent than some production blocks.

Wow, disinformation at its best.

I really wanna see Montoya storm the series like he did in CART. Once he matures a bit I think he will be an awesome blend of experienced talent and agressiveness.

They average 7500RPM.

The Dragster doesn't have a CVT or anything like that, it starts at a lower RPM and accelerates through the range...so to assume that it is at redline the whole race is false.

the offenhauser engine that was used awhile ago pushed 600 horspower out of an engine as small as my camry's. and it did 16000 rpm.

and it was good.

McLaren. I'm a Coultard fan. :)

Incorrect sir, dargsters leave the line at redline, the engine stays at redline, the clutch(s) slip almost all the way down the track.
This is why the clutch pack must be replaced after evry run ;)

Another (possibly false?) top fuel factoid I heard that was interesting:

There's enough torque on the cranks that the phasing of the pistons is off by ~20 degrees front to back from the nominal (unloaded) phasing. Supposedly this is actually accounted for by grinding the cams in a similar offset manner.

No idea if it is true or not, just heard it once and thought it was interesting.

Huh? What engine do you think they are using this season?

I don't think this could happen that easily..... ;)

I guess Schumacher will win again, as he usually performs well in Suzuka..... but next season it will be different.

For the constructors championship, team Williams will win by a few points over Ferrari.....

saturn V rocket is the biggest ballistic missle ever made. we showed the russians we could nuke the moon if we had to.

anyway, metallurgy from developing better drag motors is just as applicable as metallurgy from developing better F1 motors.

the street V10 will probably be somewhere near sqaure, so i have to wonder how much F1 technology is applicable.

Actually, it's a 3.0 liter V-10.

TOP FUEL DRAGSTER TRIVIA
  • One Top Fuel dragster's 500-inch Hemi makes more horsepower than the first 8 rows at the Daytona 500.

    Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume.

    A stock hemi will not produce enough power to drive the dragster's supercharger.

    Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition. Cylinders run on the verge of hydraulic lock.

    Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.

    At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitro methane 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.

    Spark plug electrodes are totally consumed during a pass. After ½ 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 those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or split the block in half.

    To exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.

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

    Top Fuel Engines turn ONLY 540 revolutions from light to light!

    The redline is actually quite high at 9500rpm

    The current Top Fuel dragster elapsed time record is 4.477 seconds for the quarter mile (06/02/01 Kenny Bernstein)



    Putting all of this in perspective:

    • You are driving an average Lingenfelter powered "twin-turbo" Corvette. 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, but you still run the 'Vette hard up through the gears and blast across the starting line and past the dragster at an honest 200 mph. At this moment, the dragster launches and starts after you. You keep your foot hard down, but you hear an incredibly brutal whine that sears your eardrums and within seconds the dragster catches and passes you. He beats you to the finish line, a quarter mile away from where you passed him. That, folks, is acceleration.

      Think about it, from a standing start, this phenomenal machine has spotted you 200mph and not only caught, but nearly blasted you off the road when he passed you within a mere 1320 feet.

And those engines are good for what, one or two runs before they have to be torn down and rebuilt?

pretty sure they're rebuilt after every run.
