Archie's Interesting nitro burning dragster facts:

       * One  dragster's 500-inch Hemi makes more horsepower
          than 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 then 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 electronic 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.

Vance Jaqua - Rocket fuel data tables do not agree with this statement -
with pure
oxygen as the oxidizer, the flame temperature is only about 4700 F, actually
cooler than methanol with oxygen at 5070 F. not a suprize to see the highest
flame temperature with acetylene at 6010 F with it's triple bond, With air
which is over 2/3 relatively unreactive nitrogen, all thes temperatures will
be lower. - Vance
