This was sent to me by a mate in Oz......
Some of these facts are just unreal !!!!!!!!!!!
* One Top Fuel dragster 500 cubic inch Hemi engine makes more horsepower
than the first 4 rows of Nascars at the Daytona 500.
* Under full throttle, a Top Fuel dragster engine consumes 11.2 gallons
(51
litres)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 ( 3900 degrees C ).
* Nitromethane burns yellow. The spectacular white flame seen above the
stacks at night is raw burning hydrogen, dissociated from atmospheric
water
vapour 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 RPM's from light to light!
This
one confused Stan, but stop & ponder the fact that the engine is only
used
for apx 4 to 5 seconds.
* Including the burnout the engine must only survive 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 Shumacher). 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'sgoes 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................
