This other link you provided has an internal contradiction/handwaving:
http://community.discovery.com/eve/f...8/m/2321969559

It says first:
"There are thermal losses from heat engines. From Carnot, the MAXIMUM possible efficiency from our engine is 70-75%. The real value is about 25% due to friction and the fact that the combustion is not spontaneously reversible."
Then it says:
"We know we can't affect the thermal efficiency of the Carnot cycle by very much, so 75% is still going to be "wasted". Even if the hydrogen did act as a "catalyst", there is no more energy to be released -- 99% of the gasoline does undergo combustion. A 300% gain in efficiency would imply that we are now getting 399% of the theoretically-retrievable energy that the gasoline contains (well, actually more than 399% because we also need to cover the losses from the electrolysis). This is just asinine and Carnot says otherwise. Energy can not be created from nothing -- the gasoline can NOT give more than 100% of what it has."

The writer seems to have ignored/discounted the possibility that engine changes such as later timing could reduce engine losses of friction and heat transfer to the cylinder.
The energy calculations for gas production are interesting, if correct. So far all I have found is amp needs, and of course amps is current, not energy. Tells me what to google for, which is good.
