Cool Top Fuel Dragster stats:
Some interesting Top Fuel dragster facts:
* One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona
* Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume.
* The supercharger takes more power to drive than a stock hemi makes.
* Even 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 nitromethane measures 7050 degrees F.
* Nitromethane 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.
* 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 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 pieces or blow the block in half.
* Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) 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 300mph 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.

I can't imagine.
How many g's do you think I'm pulling when I go down the line?

Would you be looking for uppercase G's or lowercase g's?

A few more interesting top fuel facts....

Top Fuel by the Numbers
It takes 900 horses just to drive the supercharger on this engine. Welcome to the world's most brutally powerful motorsport.
7500
Approximate peak output, in horsepower, of a competitive 2005 Top Fuel engine. That's almost 1000 horsepower per cylinder.
500
Engine capacity, in cubic inches. The block and heads are CNC-milled from solid billets of aluminum, and the oil pan is titanium.
45.5
Maximum boost, in psi, produced by the supercharger at wide-open throttle. That's more than 3.0 bar, twice the boost achieved by a Mitsubishi Evo VIII.
12,654
Rpm the supercharger spins at maximum engine speed. With the engine at 8500 rpm, just turning the supercharger soaks up 900 horsepower.
165
Temperature in Fahrenheit of the 14-71-type supercharger after just 4.5 seconds of maximum boost.
569
Number of times the engine's crankshaft turns during the entire quarter mile. Each intake valve opens 284 times.
16
Spark plugs per engine. The twin MSD magnetos produce 88 amps. You need just 12 more to power your MIG welder.
77
Gallons per minute the fuel system can pump at wide-open throttle. The engine will consume 22.75 gallons of fuel during warmup, burnout, staging, and the quarter-mile run.
900
Cost, in dollars, of a 55-gallon drum of nitromethane fuel. Current regulations allow a maximum of 85 percent nitromethane in the fuel mix. The rest is alcohol.
58,700
About what you'll pay, in dollars, for a new, ready-to-run Top Fuel engine.
29
Minutes it takes to tear down and rebuild a Top Fuel engine between rounds. Each engine is rebuilt 184 times a year (if the driver goes to the final round at every race).
28
Quarts of oil used during warm-up and quarter-mile run. The oil pan holds 70-weight oil mixed with special thickener.
6
The maximum number of clutch discs in a Top Fuel car. The multistage clutch is timed to progressively lock up during the run. Each $115 disc lasts a maximum of three runs.
Here's What It Drives...
2225
Minimum weight, in pounds, of a Top Fuel dragster. That's a power-to-weight ratio of 3.37 horsepower per pound, about 20 times better than the new Z06 Corvette's.
300
Wheelbase, in inches, of a Top Fuel dragster. About 3000 inches of chrome-moly tubing is needed to build the frame, which is left unpainted because of the need to constantly weld cracks.
1082
Greenbacks you'll need to buy a pair of new Goodyear R36x17.5 rear slicks. If you're lucky, they'll last you a bit over a mile--four runs.
58
Bead Lock bolts used to retain each rear tire to the wheel. Tire pressures are set between 6.5 and 7.5 psi.
...And Here's What It Does
0.84
Seconds it takes for a Top Fueler to accelerate to 100 mph from standstill. At launch, drivers are subjected to up to 4.75 g--more than a space-shuttle astronaut.
333.08
Top speed, in mph, of the 2004 NHRA Top Fuel Championship-winning U.S. Army dragster. When he pops the parachute at the end of his run, driver Tony Schumacher experiences peak deceleration of 6 g.
12,000
Downforce, in pounds, generated by the rear wing at 325 mph. The downward thrust made by the exhaust gases escaping the headers alone generates 800 pounds of downforce.
85
Distance, in inches, you'll need to be above the header pipes to avoid getting toasted by the nitro flames exiting those pipes.
8.5
Number of inches the rolling diameter of the rear tires grows during a 325-mph run, reaching a maximum of 44.5 inches.
It's Short but Sweet
4.441
World-record elapsed time, in seconds, it took Tony Schumacher's Army dragster to cover a quarter mile.
18
Seconds of racing completed if Tony makes the final. If he makes the final in every race, his total racing time for the season will be less than seven minutes.
