temperature at which water will start to break down into its elemental components is 4939 fahrenheit. which are hydrogen and oxygen, both of which would help burning holes. that temp will be considerably lower under high pressure (as in an engine). I might do the math tonight. and I also seem to remember something about water injection to make engines run better on the salt flats. california bill's book on stovebolt speed. any old hotrodders that know more? this IS getting interesting..
