HHO Systems.

Runs even better on an EFI engine too.

 

I guess I will have to figure out that one too.

 

You could set it up as they show it in that article, and see how you like it for a couple tankfuls, and then decide if you want to do anything else or take it all out. I like simple stuff.

 

Yeah I am also reading about WAI to see how it helps fuel economy.

 

I am sure it does, I just don't know the full physics behind it. I have recorded fuel usage on my cars for years and there is a clear difference between summer and winter. Summers are around 5% better, so I guess that would be the ballpark figure for gains when heating the airbox. But don't forget about the amount of energy needed to heat the box in the first place.

 

Something like this but it is a long read.
