I quit reading when he claimed that he was running with a fuel/air (f/a) ratio of 40:1, Gasoline will only ignite with a spark in a very narrow range of f/a ratios;something like 12-16:1. My bet is it's snake oil. There's only so many BTU/gallon in a gallon of fuel. No ammount of spark energy is going to release anymore than that and the engine at best is maybe 28% thermally efficient so 28% of those BTU's in the fuel are going to be available to do useful work. Modern ignition systems are probably releasing 99.9% of the fuel energy already so I don't see where the big savings can come from.
