Today my roomate, who works at Advance Auto, came home and told me of a guy that stopped in and had a hydrogen setup where he had a tank in his truck and it would "shoot" hydrogen into his intake. He said he gets about 25 mpg in town and about 36 mpg on highway with a '94 chevy 2500 with a 350!! There are plenty of "claims" online that say it can help, is there anyone here who has tried this themselves or knows of someone who has??

 

was it a dihydrogen oxide shot? AKA HHO or more commonly known H2O?

 

From what I was told he had a hydrogen converter set up inside his engine bay with a small tank that will convert H2O to hydrogen gas and has it tied into his intake. I've read a little online about them and they "claim" to improve gas by up to 70%, he also said he has a small 4 cylinder car that gets 56 mpg.

 

For a limited time does it come with snake oil? That stuff also improves gas mileage.

 

Kinda glad this was brought up.
A week or so ago I had a guy in my shop saying he was gonna build a HHO kit for $25. So we chit chatted for a few and I got curious came home and searched on youtube about it and found lots of info. I really am intrested in trying what I have seen. But I am still doing alot of research cause alot of the kits I seen were sketchy on details. Seems easy to make but there are precautions to take. Like installing a "bubbler" aka arrestor (spelling) and whether to use baking soda or some other sort of additive I forget what it was called. But seems like a fun project and something I would really like to get into.
Anyone have experience with HHO?

 

I dunno, there is alot of lies and cover ups about HHO gas. I DO know that baking soda is out, you should use potassium hydroxide, much more H2 production.

 

yeah thats what i was thinking of potassium hydroxide. the baking soda works but quickly rusts the plates or windings depending on which you use.

 

I've been monitoring my engineer neighbor for a while now. He's got the kit set up in the engine compartment of his cavalier. Said he went from 30mpg's to 50mpg's at first. Then he began tweaking for more and dropped to 40.
He continues to tweak it. The first setup with crossed plastic configuration wrapped with wire, oxidized quickly...he is using baking soda mixture. He then went with 2 stainless steel threaded rods instead of the plastic. Seems to be working better. I'll mention the hydroxide to him, maybe he'll give that a go.
ONce he gets it ironed out, I'm planning on sticking the system into my 4.6 Screw.
Can't think of any reasons to not try it and being so cheap a system, would pay for itself rather quickly if it pans out.

 

TazzRider, keep us updated on his project. The baking soda might be why he is getting the accelerated oxidation on his wires. He is using stainless steel correct? Every setup I seen they said to use 409 stainless steel IIRC.
Also find out how much voltage and amps he is running at. And or if he is using an amp gauge. From what Ive seen the soda is to get the amps up and that creates more HHO. Also if he knows how many liters or gallons of HHO a minute or an hour hes making. There are videos on youtube that show you how to test and see how much HHO your creating.

 

yes, he went with 2 - 3/8 threaded rod last i checked. He previously used tap water, which is really nasty here, so that didn't help. Said he would try distilled water next.
While watching the bottle in his setup, he started the Cavalier, I don't know the hydro measurement but it began producing it within 15 seconds or less.
I would love to get another 5 mpg's out of my 4.6, especially for under $50 setup.
Will report back as i learn.

 

Thanks for the info. I will be indulging in this project asap myself.

 

I think I'm going to give this a try but still trying to figure out what all i need. Does anyone know where I could get some plans for this that wouldn't cost anyting?

 

just search on youtube.com for HHO do it yourself and stuff like that

 

there are already a lot of threads on this board about "HHO" setups. Serach and read. I've been looking into it extensively. You'll have to do some modifications to your MAF or use something like an EIAA or something. (think thats what it;s called) It will modify your air to fuel ratio to either richen or lean out your system for the added Hydrogen. Once again, I forget which. Google hhoforums and read there also. I'm almost to the point of being scared about running the motor lean or rich and running out of water to created hydrogen and ruining my motor.

 

The "HHO" by itself is worthless.

You have to screw with the O2 or MAF sensors to force the engine super-lean to up the fuel economy. At that point, you can throw the HHO in the trash since is't just a drag on the system.

Of course, running an engine super-lean that was not designed for it will mean either valve or piston damage.... So, enjoy your "savings" while they last since you'll be spending that money on engine repairs or repacement.
