Re: Increased MPG
Just did a little math in my head. I may be wrong here but....
9.4 mpg to start
23.2 mpg after the test period
they said that was a 61% increase????
If it's all true wouldn't that be almost a 150% increase over 9.4mpg????
9.4mpg + 9.4mpg (100%) + 4.7mpg (50%) = 23.5mpg (150%)
Nice math Florida News Guy!

Re: Increased MPG
61% of 23.2 mpg = 14.152 mpg
14.152 mpg + 9.4 mpg = 23.552 mpg
Does that make sense?

Re: Increased MPG
Here's another hydrogen system- http://www.thermo1.com/index.htm

Not really, by the Florida News Guy math above a 61% increase on 9.4 mpg would be:
9.4mpg x .61 = 5.734 + 9.4 = 15.13 mpg

Re: Increased MPG
I've read thru both websites. The hydro-4000 sounds like the better option, although more expensive. I don't see why you can't have a larger reservoir somewhere so you're not refilling the small container so much. There's no mention anywhere about durablility or maintenance. I'd like to see some long term testimonies. I've sent both companies an email requesting more info but I think I'm going to give this a shot.
My brother is a green freak and I talked with him about this. He's checked into it before but hasn't done it yet. He's excited to try though. He mentioned that the only issues he came across was a problem with the O2 sensors reading to much oxygen in the mix and the computer increasing the fuel.
Is there anyone else here that has any knowledge of the pros/cons of this?

Re: Increased MPG
Must be popular, the website www.hydro4000.com is getting hammered right now. Gotta admit that watching that news story has me more than a little curious about it.

Re: Increased MPG
It would have been incredibly easy for the dyno operator to run the system with a very heavy load the first time, resulting in a below average MPG, and then with a super light load (lower than would be experienced on the road) the second time, resulting in an above average MPG rating.
The news reporters would have been clueless, as could be the general public.

Re: Increased MPG
If you are going to do this. You have to disable the sensors in your CAT. Which is illegal. I talked to a guy who was installing them in vehicles and the computer dumps more fuel in when the sensors say that the engine is running so clean. Put a loop signal on your sensors hooked up to a toggle switch so that when you go into a shop for inspection you won't get fined. I don't know how or if you would get fined but when I told the shop owner this he scolded me and said that "that is illegal". I am trying to see if you can get an exempt sticker if you prove that your vehicle is running cleaner then stock. But I doubt that it will go anywhere. And for anyone really looking into this technology research Stanley Meyer and see what happened to him (Poisoned). His ideas can be found online and there is a shop online selling kits to make the "H" "H" "O" generators. if anybody figures out how to trick your computer into not dumpiing more fuel into the engine after hooking the device up. Post it!

One of the simplest and cheapest solutions to the Check Engine Light's generated after removing a catalytic converter is to install to o2 sensor spacers, available from any auto parts store, before the o2 sensor itself, effectively pulling the sensor out of the stream. I wouldn't be surprised if this trick would work for this problem as well.
If you go through with this, please let us know how it works out.

Re: Increased MPG
Hey Moore, if you do the spacers that you suggest, does that fix the issue of the O2 sensors reading lots of oxygen and trying to increase the fuel?
I've spent the last 20 minutes or so searching for Stanley Meyer info. After sifting thru the government conspiracy crap, it seems he was more of a scam artist than inventor. He also was trying to run his vehicles purely on hydrogen (if I find more info later I'll post it, but that's all I have time for now). These systems talked about above are just adding hydrogen to the standard gas mix.
