I've researching making a unit to run Hydroxy on my slant six. I'm already running a little rich at 7000 feet. I have not been able to discern which carb I have, either the carter or holley and I don't know what year my engine is. I have a 1982 150 van made in canada. UNder the hood it has documentation for 318, so somebody put this slant six in there and I don't know what year it is. The dodge dealer has been no help there computer doesn't go back that far, and I most of the guys never heard of a slant six! There is no tag on the carb, but i found these numbers on body: 4287015 8762 2461

When I remove one of the vacuum lines on the left side of the carb it actually idles faster and smoother?? Is it ok to run like this? I was also thinking of removing the main jet and epoxying a fine mesh screen over the orfice to help vaporize the fuel more effeciantly while leaner the mixture. How crazy is that. Where can I obtain a smaller jet when I figure which carb I have? thanks

Hello and welcome. Pictures would be a HUGE help here. Your rich running problems may be due to something besides the carb, especially if a previous owner did an engine swap and other things to the van. The first step to fixing your problem is to identify exactly what you have.

Welcome. Unfortunately I don't think either of those ideas are going to work. You'll take more power from the engine to make the hydroxy than you could get back by burning it, and replacing a jet with a mesh screen is going to have weird and unpredictable (but almost certainly not beneficial) effects, along the lines of adjusting your points with a sledgehammer.

But you will find plenty of help getting it fixed here. I'm not terribly surprised if it's running rich that creating an air leak would lean it out, but you'll want to fix it correctly. What hose is it that removing has an effect?

Are you sure your hood wasn't replaced? My brother has a 83 van that has a slant six from the factory but the hood was replaced with one from a 318 equipped van.

never thought about the hood being replaced... And I have no idea which vacuum line, I don't know what was there before, but I've been running a water injection system through it. As far as the comment on hydroxy, there are alot of people out there doing this and getting anywhere from 20 - 50% increase in milage. There are forums for such (http://tech.groups.yahoo.com/group/Hydr ... Rows&tbl=3) Perhaps you misunderstand the concept: the hydroxy is produced using anywhere between 10 to 20 amps and is used only as a fuel supplement to make a faster and more complete combustion and is used along with the regular fuel injection or carberation. On cars with computers and O2 sensors you can use some electronic devices to lean the fuel air mixture. But on older vehicles I 'assume' you must change the jets in the carb. I was hoping some one out there has had experience with this....I actually had the carb rebuilt a couple of years ago, and it isn't running that rich, I'm just at nearly 8000 feet now.

You're producing Brown's gas which has the correct air/fuel ratio for H2 and O2. So if you introduce the Brown's gas after the carb into the intake manifold, you won't have to change anything on the carb; as the carb will add the correct amount of gas for the air that's gone thru the carb............

I've seen these claims, I've also seen a lot of claims saying, "It doesn't do anything." But I've never seen someone carry out a properly controlled test - for example, back to back dyno tests with the system on and off to see if it's making it burn more efficient, or submitting it to an EPA-approved lab for the same sort of tests that they submit new cars to - or even using something like Consumer Reports' relatively controlled fuel economy test loop. Until that happens, I suspect most of it is hype just like the Tornado Fuel Saver.

Most of these systems deliver under 10 grams of hydrogen per hour. By contrast, my little Honda has four injectors that each flow 23 pounds per hour. That can deliver more fuel by weight in one second than your typical HHO generator can deliver in a whole hour. Which is more likely, that a tiny amount of hydrogen can create a 50% fuel economy improvement, or that the guy making those claims didn't do a good job of testing his mileage?

If you just look at the energies involved in producing the H2, and what you get back from burning it, there's no way it should work.

But if the small amount of H2 with gasoline improves combustion efficiency somehow, you could very well get better mileage.

If you're making the system yourself, it's not the expensive to try.


And if it doesn't work, you can always use the equipment to make explosive balloons............
