Hey Ya'll,
Just in case you haven't seen this I wanted to send it again after discussing the facts with some Top Fuel friends of mine. After crunching some more numbers pertaining to clutch settings this is what I believe to be a little more accurate;
7000 rpm burnout =350 rpms light load
4.5 sec run @9500 = 711 rpms
2 +secs before clutch lockup = 300+rpms
still only turns 1361 rpms in 1320 feet
With a 116" rollout rear tire thats 136 revollutions with perfect traction !!!
With a 250 mph roll thats a football field a sec. he ain't catchin' the roadster !!!
Drive fast and take chances, WILL
ACCELERATION PUT INTO PERSPECTIVE:
>
> >
> * One Top Fuel dragster outfitted with a 500 cubic-inch Hemi engine
> makes more horsepower (8,000 HP) than the first 4 rows at NASCAR's
> Daytona 500...
> ( Aaarrgh !! )
>
> * Under full throttle, a dragster 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 merely

>
> (awwwww man, come on... ??!! )
>
> * 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 locku p 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 stack s at night is raw burning hydrogen, dissociated from
> atmospheric water vapor by the searing exhaust gases.
>
> * Dual magnetos supply 44 amps to each=2 0spark plug. Which is
> typically the output of an 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 enou gh force
> sufficient to blow the cylinder heads off the block in pieces or split
> the block in half !!
>
> * Dragsters reach over 300 MPH +... before you have completed reading
> this sentence.
>
> * In order to exceed 300 MPH in 4.5 seconds, a dragster 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. ( Aiiiii chihuahua !! )This guy does'nt know Speedy's clutch setup !!!
>
> * 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, & NOTHING BLOWS UP, each run will cost an
> estimated $100 0 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=2 0starting 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....or snapping your fingers !!
>
>
> 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).
>
> So, in summary...Let' s now put this all into perspective:
>
> Imagine this....You are driving a new $140,000 Lingenfelter twin-turbo
> powered Corvette Z-06. Over a mile up the road, a Top Fuel dragster is
> staged & 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
> dragster at an honest 200 MPH.... The 'tree' goes green for both of
> you at that exact moment.
>
> The dragster departs & starts after you. You keep your foot buried
> hard to the floor, and suddenly you hear an incredibly brutally
> screaming whine that seares and pummels your eardrums & within a mere
> 3 seconds the dragster effortlessly catches & 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 it not only caught, but nearly blasted
> you off the pl anet when he passed you within a mere 1320 foot long race
!!!!

> That my friends..... is acceleration
