HHO: Is it alchemy? Or will it improve gas mileage on a ’99 4.0 SOHC Explorer?

[FIND]

Yeah, that is exactly what I am saying, because it wasn't any "Just" an HHO generator that gave you a 37% increase in fuel economy. Hell, the Jet Propulsion Labs testing with bottled hydrogen couldn't generate that kind of increase, and they didn't have to deal with the parasitic drag that you have generating the hydrogen. Why was your Celica only getting 22 mpg anyway? Those things should get pretty near 30 bone stock on the highway. You know, if you had such an efficient electrolytic cell then, what is the problem now? Ever notice how many "experts" that support HHO keep saying how they aren't using it right now, or they aren't getting X increase right now, but that is only because they haven't built their planned cell yet?

But hey, don't trust me. I only referenced testing by the Jet Propulsion Laboratories, Popular Mechanics and THOUSANDS OF SCIENTISTS OVER THE PAST CENTURY AT CREDIBLE UNIVERSITIES. Some guy on the internet wrote a convincing article utilizing massive amounts of psuedo-science and you have experienced changes in FE that you couldn't explain.

If it helps, even Nikola Tesla thought generating hydrogen through electrolysis was really inefficient and tried to improve on it. He claimed to have done it, but through much more exotic means than you are talking about.

Yes, adding hydrogen to combustion and proper tuning can increase FE and lower emissions, but as you'll see, the methods used for adding said hydrogen are much more exotic than a stacked plate electrolytic generator and not feasible for use in daily driven automobiles. Any testing by credible organizations using electrolytic generation of hydrogen has ALWAYS demonstrated it is an inefficient process.

My Celica only got 22 MPG before the HHO because it was a second gen RWD with cam and weber carb and a few other mods. I regularly thrashed it every time I started it. It basically lived at red line unless on a long trip. I regularly made a 150 mile trip from school to the parents house, I always used the same amount of fuel for the trip give or take some. After installing the generator, I used far less. I could then go to the parents house, do some mild driving around town, then return to KY on one tank of fuel. Before the HHO I would always have to top off @ parents.

I'm building another unit large enough for the Ex. Please don't call me a liar when I post my results.

Yeah, that's fine. I don't care how you waste your money. Just don't tell other people to waste theirs.

edit: Did you ever think that maybe the cause for your change in mileage was that your 22 mpg rating was based on the fact that you

I regularly thrashed it every time I started it. It basically lived at red line

Either way... I'm gonna take the rocket scientists word for it when they couldn't get an increase near as large as that when running bottled gas... Just saying, guys at NASA have a little better engineering credentials than a random guy with a Celica who buys into psuedo-science from the internet.

I wish you well, really. But the reality is that there are so many factors affecting mileage, that most people will not have every needed item(such as PCM programming different for both fuels used), or a combination of good and bad tune up items.

I would bet that your Celica could get very close to 30mpg with the right tune etc, but I don't want to spend time to debate that. Regards,

Just want to finish with this...

I think it is appropriate here. I'm off to the pool.

LOL, I like water slides too

After reading all of the threads, I realize that we can all add the hardware and make the same modifications to our vehicles but the missing link will be the PCM tune. The tune is what will bring everything together. The AH-HA moment just like post #461 of this thread. I would be glad to just get to 30mpg for highway driving.

Does anyone have any ideas that they are willing to share with the group?
Thank you.

I am a big guy who just likes his Explorer and loves to drive it.

I've started to build one and I'm currently looking for the best option to address the MAP issues. There is a lot more to HHO then they tell you in these cheap glass jar kits that you see for sale. I've been doing my research and studying a lot on the subject. I advise you to lean as much as you can about it before you attempt to install an HHO in your vehicle. I'll be posting my findings on this site when I get the bubbles flowing to share my knowledge.

Be sure and let us know how you are measuring the gas output, and how you are changing the engine operating parameters to compensate for that un-metered volume of gas.
