I would imagine, with this information being from
2004 or so, the prices have likely doubled......but what the heck---
You go as fast as your wallet is deep!!!

Subject: Acceleration A must READ!! Off
subject, but intreseting
I would just like
to state, that to the best of my knowledge, they all run hemis. And the last
part is simple amazing. Hope you enjoy and don't flame me to much.

Gentlemen, It’s not flying as we know it but 747’s do get
a mention! Guys, this is a good read and please pass it on
to our buddies that like speed.... Read this thru slowly and try to comprehend the
amount of force produced in just under 4 seconds! 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!
