If you thought Top Fuel Dragsters were fast (over 300 mph in less than 5
seconds), this really puts it into perspective.
This came from a guy that makes connecting rods for the racing industry.
* 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.
* 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 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 lockup 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 stacks at night is raw burning
hydrogen,
dissociated from atmospheric water vapor by the searing exhaust gases.
* Dual magnetos supply 44 amps to each sparkplug,
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 enough force sufficient to blow the cylinder heads off, the block in
pieces or split the block in half!
* Top fuel 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 9000 revolutions under
load.
* The red line 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 $1000 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 starting 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 sears
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 planet when he passed within a mere 1320 foot
long race!
