Ok... so it looks like with a change in the muffler, catalytic converter, Cold Air Intake and Water Injection.... I should be getting 50-75% increase in mpg. At a cost of uder $700...
So that looks to me like about $6000 - $8000 a year in fuel savings. I can live with that ... and that does not even have to use HHO.
NOW... with all of these other enhancements... and given that my vehicle is a 2002 Ford Expedition (Eddie Bouer Edition)... And a calculated 70 Lpm need for HHO (per someones previous post in this thread). Am I really going to see enough extra benefit to proceed with a Hydroxy Generator?
