Infinitesimally small levels of HHO will yield even infinitesimally smaller levels of results.

If you want to increase oxygen levels do what all the old people who smoked all their lives are forced to do, get an oxygen concentrator.
If you think Ozone is the key to everything take the oxygen concentrator and run an electric arc through the oxygen stream. That will get as much or as little Ozone as you want. It will far surpass and be much more controllable then what an HHO cell will provide.
If all you are trying to do is increase burn speed there are several things that can be done to increase a gasoline engines air fuel burn speed. The addition of nitrous oxide or just simply increase compression.

Everything you want to test would be so much better tested with something other than an HHO cell. So why the obsession with HHO when its clearly not what you need to do the test?

Seems you have already determined you need an HHO cell for what ever reason, now you are just trying to justify it.

If you don't like it, there are plenty of idiot free HHO forums out there to spread your pathological science on.
