90000 lbs of thrust and I'm only allowed to go walking speed when I get to drive

Nice Pic,
 I am pretty sure the Hayabusa can take that truck on a road course though...He will run out of Parachutes eventually, and without brakes, we should be able to get him...Just DO NOT try to Pick up a draft!!!

I think that is the same truck that I saw at an air show. Racing a f-15 fighter jet. The truck one. Jet was just coasting for a good show. I think I want one of those trucks for the Freeway. Pull away burn they up."

PDA Speed is relative





* 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 nitromethane measures 7050 degrees F.


* Nitromethane 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 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
those cylinders and then explodes with a force that can blow cylinder heads
off the block in pieces or split the block in half.


* Dragsters twist the crank (torsionally) so far (20 degrees in the big end
of the track) that sometimes cam lobes are ground offset from front to rear
to re-phase the valve timing somewhere closer to synchronization with the
pistons.


* 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.


* If all the equipment is paid off, the crew worked for free, and for once
NOTHING BLOWS UP, each run costs $1000.00 per second.


* Dragsters reach over 300 miles per hour before you have read this
sentence.


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


* The redline is actually quite high at 9500rpm


* The current TF dragster elapsed time record is 4.477 seconds for the
quarter mile.


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, gentlemen, 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.

Now....., tell me about the time you spun the wheels and laid rubber on dry
concrete in second gear. I really would like to hear the story.
