There are no rockets or airplanes built by any
government in the world that can accelerate from a
standing start as fast as a Top Fuel Dragster or Funny
Car!

DEFINITION OF ACCELERATION
One top fuel
dragster 500 cubic inch Hemi engine makes more
horsepower than the first 4 rows of stock cars at
the Daytona 500.
It takes just 15/100ths of a second for all 6,000+
horsepower of an NHRA Top Fuel dragster engine to
reach the rear wheels.
Under full throttle, a dragster engine consumes
1-1/2 gallons 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 Hemi V8 engine cannot produce enough
power to drive the dragster's supercharger.
With 3,000 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 (stoichiometry: methodology
and technology by which quantities of reactants and
products in chemical reactions are determined) 1.7:1
air/fuel mixture of nitro methane, the flame front
temperature measures 7,050 deg 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 halfway, the engine is dieseling from
compression, plus the glow of exhaust valves at
1,400 deg 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 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
from light to light! Including the burnout, the
engine must only survive 900 revolutions under
load.
The redline is actually quite high at 9,500 rpm.
Assuming all the equipment is paid off, the crew
worked for free, and for once NOTHING BLOWS UP, each
run costs an estimate $1,000.00 per second.
The current top fuel dragster elapsed time record is
4.428 seconds for the quarter mile (11/12/06, Tony
Schumacher, at Pomona, CA). The top speed record
is 336.15 mph as measured over the last 66' of the
run (05/25/05 Tony Schumacher, at Hebron, OH ).
Putting
all of this into perspective:
You
are driving the average $140,000 Lingenfelter
'twin-turbo' powered Corvette Z06. 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 'Vette
hard 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
moment.
The dragster launches and starts after you. You keep
your foot down 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 1,320 foot long race course.
...... and that my friend, is
ACCELERATION!
