found this a while back and came across it again and thought I'd share it. Pretty crazy stuff!
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 top fuel dragster engine consumes 1 1/2 gallons of nitromethane every second; a fully loded 747 consumes jet fuel at the same rate with 25% less energy being produced
A stock Dodge 426 cubic inch (7.0 liter) Hemi V8 engine cannot produce enough power to drive the top fuel dragster's supercharger
With 3000cfm 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 nitromethane the flame front temperature measures 7050ºF (899ºC)
Nitromethane burns yellow. The spectacular whate flame seen above the stacks at night is raw burning hydrogen, disassociated from atmospheric water vapor by the searing exhaust gasses
Dual magnetos supply 44 amps to each spark plug
Spark 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 1400ºF (760ºC). The engine can only be shut down by cutting fuel flow
If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinder(s) and then explodes with sufficient force to blow cylinder heads off the block in pices or split the block in half
In order to exceed 300mph (483kph) in 4.5 seconds, dragsters must accellerate at an average of over 4G's. In order to reach 200mph (322kph) well before half-track, the launch acceleration approaches 8G's
Dragsters reach over 300mph before you have finished reading this sentence
Top fuel engines turn approximately 540 revolutions from green light to cut off. This one's confusing, but stop and ponder the fact that the engine is only used for approx. 4 to 5 seconds
Including the burnout the engine can only survive 900 revolutions under load. The redline is 9500RPM
