Dear god, people are still pushing the HHO scam, Can one single person provide a single legitimate dyno chart, Certified emission test, Or data logger that shows less fuel is being use with the system on vs off? If you have to look through 30 pages of post or hours on the internet you have already answered your question.
If you cannot increase horsepower without using more fuel at the same engine load then you cannot increase fuel economy period!! Nobody can even show a 5hp gain with this junk, let alone 20hp to 30hp which still would not yield you the ridiculous claims of 25% to 30% better fuel economy.
When challenged to do a simple $40 to $60 dyno test, or even cheaper emissions test to show more complete and efficient combustion HHO'ers will always fail to provide any proof. All these threads end the same, just a bunch of I'm still working, tweaking, experimenting, ect, ect with my kit.
Here is a simple way to prove when less fuel is use, Data loggers are cheap, I'm amazed nobody has bothered to do it.
This is just a example nothing to do with a gas engine but just shows you how easy it is to prove fuel savings.
Data logger cost all of $400 to $200 bucks.
This is water injection on a diesel 1.9TDI VW
Off
On
See easy
Dyno's to show hp just as easy but not one real one exist for HHO, Find one if you can. Lots of empty headed techno babble with out a real test to prove anything.
Sorry the whole HHO scam gets under my skin. Feel free to provide the above mentioned documents that are not copied and pasted from a scammer sight.
