The other point is if the HHO is injected far enough from the MAF so there is enough time and space for the HHO to mix with air there is no way, with the amount of HHO being injected, it could ignite. Injecting it right next to the MAF, where pure HHO could hit the heater on the MAF, would be dangerous and should not be done. I think it is more a safety issue than any thing else.
Some tests reported by others have shown that injecting after the MAF does give better results but why, is not at all clear to me anyway, and in some resent tests I have done I found no difference that was measurable. I have only theories but no hard science or test data that show why. The amount of HHO injected compared to the total volume of air is so small that I doubt the MAF can tell the difference. I can only see where large amounts of HHO or HHO that has large amounts of moisture in it making a possible difference. I would like to hear what others think.
