ACCELERATION PUT INTO PERSPECTIVE
* One Top Fuel dragster 500 cubic-inch Hemi engine makes
more horsepower than the first 4 rows at the Daytona 500.
* Under full throttle, a dragster engine consumes 11.2
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 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 lock 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 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
* Dragsters reach over 300 MPH before you have completed
reading this sentence.
* In order to exceed 300 MPH in 4.5 seconds, dragsters must
accelerate an average of over 4 G's. In order to reach 200 MPH well before
half-track, the launch acceleration approaches 8 G's.
* 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 9500 RPM.
* THE BOTTOM LINE: Assuming all the equipment is paid
off, the crew worked for free, & for once, NOTHING BLOWS UP, each run costs
an estimated $1,000 per second.
The current Top Fuel dragster elapsed time record is 4.441 seconds for
the quarter-mile (10/05/03, Tony Schumacher). The top speed record is
333.00 MPH (533 km/h) as measured over the last 66' of the run (09/28/03,
Putting this all 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 &
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 & pass the dragster at an honest 200 MPH.
The 'tree' goes green for both of you at that moment.
The dragster launches & starts after you. You keep your foot
down hard, but you hear an incredibly brutal whine that sears your eardrums
& within 3 seconds the dragster 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 & not
only caught, but nearly blasted you off the road when he passed you within a
mere 1320 foot long race!
That's acceleration !
Big Daddy is in this Beesh...........

Can't believe those things are still getting faster. When I first started watching them, they topped out at 275 - 280mph. I stopped watching about the time they hit 300, it was a huge deal. Now they are at 330+?! Dayummmm

Yes they are. I've always said that when they launch the world stops for until they finish because you are so consumed and mezmorized by them. EVERYONE should experience these once in their life there is nothing else like it in the world. 10 times louder than a monster truck.
