Thanks for investing in a pressure spark plug Rusty (and bringing such a device to my awareness). Would love to see the experiment in any event and I enjoy thinking about this stuff in more detail than I had previously. I do have one other operational caveat to theorize though, P&G hypermilers already target bsfc, which is on the low side of rpm and the high side of load, where ignition timing is fairly close to tdcc. I don't see how hho will help peak bsfc(would hurt it a tiny bit actually), or help a driver who's operating the vehicle with bsfc in mind since there is minimal, if any, area under the curve left of tdcc under those conditions. Am I missing something there, or is that fair speculation? Gasoline engine assumed.
