Gotta love the awesome power of a 'Top Fuel' dragster.
Nitro for the win!!!

Remembering the first time I got a good wiff of nitro and thinking I would never catch my breath it always amazes me to watch those guys just bury their faces in the headers and get soaked in it.

Amazing the kind of power they make. The ground shakes when the throttle is touched....

* 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.

*The crank in a top fuel dragster only rotates 540 times from start to finish of a 1/4 mile.

*Including the burnout the engine must only survive 900 revolutions under load.

unbelivable!!! just about breaks all laws of physics. NOW I been askin this question for about 5 yrs. when?? NITRO thru a rotary. Ron in Austin

I've been reading up on mixing nitro with my methanol for aux injection. There is no information about it and rotaries that i can find though. I've read about some of the buick guys that have had decent luck with it though.

Got to love it !! Best experience ever feels like you leave the ground standing next to the race car .(been there done that) nice

How do I make these cars legal to drive on the street?
