Top Fuel Drag Racing facts
One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona (or Bathurst 1000)
Under full throttle, a dragster engine consumes 1 1/2 gal. of nitro per second, the same rate of fuel consumtion as a fully loaded 747, but with 4 times the energy density.
The supercarger takes more power to drive then a stock hemi makes.
With nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition.
Cylinders run on the verge of hydraulic lock.
Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitro methane measures 7050 degrees F.
Nitro methane burns yellow. The spectacular white flame seen above the exhaust stacks at night is raw burning hydrogen, dissociated from atmosphierc water vapor by the searing exhaust gases
Spart plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression plus the glow of the exhaust valves at 1400 degrees F.
The engine can only be shut down by cutting off its fuel flow. If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in peices or blow the block in half.
Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the crank) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons.
To exceed 300 mph in 4.5 seconds dragsters must accelerate at an average of over 4G's, but in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.
If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second.
Dragsters reach over 300 miles per hour before you have read this sentence.
Top fuel engines only turns 540 revolutions from light to light! Redline is actually quite high at 9500 rpm.
To give you an idea of this acceleration, the current TF dragster elapsed time record is 4.477 sec. for the QTR mile. This means that you could be coming across the start line in your average Lingerfelter powered "twin-turbo" Corvette @ 200 mph (on a flying start) and the dragster would beat you to the finish line From a dead stop in the quarter mile distance!!!!

I thought it was pretty interesting myself, so I thought you gear heads would like it too.

The only way a PT Cruiser's going to beat that is if the Top Fueler had a cow-catcher on the front and it pushed the Cruiser along! [8)] *LOL*

Err, maybe if the TF'lr red lights, and sleeps at the light, then haze's the tires then breaks something major
Nah, never mind.

cool stuff. Do you think wheel hop will be an issue with Stage 28?
