Sounds sweet.
One thing I'm thinking about is when a gas combusts it releases it's energy as both heat and pressure. H2 and O2 not only burns quickly, it also produces steam which wveeyone knows has a huge expansion ratio.

Yes Nitrous Oxide
The test will be a very simple one. I'm basically using a leaking nitrous solenoid I have laying around to use for the test. Set fuel cells so it can't hunt for a richer cell, then lower the ignition advance at 50mph 30:1 A/F with nitrous enable and repeat with nitrous disable and increase ignition advance.

I've seen some calculations there suggest the theoretical maximum thermodynamic efficiency of any OTTO cycle ICE is around 46%, and both Honda and Toyota have exceeded 40% without direct injection. That really doesn't leave a lot of room for HHO to improve things in an already well-tuned engine.

I think the key is engines that are lean burn will need always have a slow flame front. So the manufacturers are working on different ideas to increase the flame front during lean burn. The non lean burn engines are pretty close to ignition at TDC and are producing great numbers, so they wouldn't gain to much from a faster flame front.
