The 100 mpg carb - Does it really exist?

Hi Dave,

Sorry I have been so busy lately we have had a number of family members in the hospital for various reasons this past month. Installation should really take nothing more than some of your time and the following items:
10GA or heavier wire from an old pair of jumper cables (in good condition obviously)
A small switch (free?)
An in-line Amp meter with a 50A shunt (24 bucks from AllElectronics.com)
An automotive grade Relay rated for at least 50 or 60 amps (McMaster.car has nice ones 100A waterproof for 20 bucks)
Some small gauge wire for the meter and switch
My Electrolyzer

I also believe I found a way around the 02 sensor issue; at least on my new Buick. I will have to take a picture of what I'm talking about but there's a small nipple covering a port right on the very top of the engine. When I pull the little rubber nipple off and connect my vacuum guage up to it, it registers about 25 inches of Mercury vacuum as soon as the engine is started. Well folks this is damn near perfect! It appears to be after all of the sensors basically sitting right on top of my engine block. -Again I'm not a car guy here so please forgive me. It's the solid cast aluminum piece (Manifold?) on top that has this little port.... probably for diagnosing leaks? -So I'm thinking this will be the perfect place to inject the hydroxy. It's well after the 02 sensor, perhaps 20 or more inches.

So where are you located Dave? I'm in Lancaster, PA. If you're close enough maybe we can work something out to get one of my units into your test vehicle. I would imagine that either one is fine to use. As I stated before I have been working very hard on the electrolyzer side of things for the past 6 years and have one of the most solid electrolyzer units you will ever find for an automobile. But my knowledge abruptly ends at the end of my hydroxy tube.

I can tell you that you are confused about the sensors. The O2 sensor is not in the intake system at all - it's in the exhaust system. If you are looking at a sensor that is well upstream of the throttle body, you are probably thinking about the MAF (Mass Air Flow) sensor.

Have you actually tried to implement what you are proposing?

Unfortunately it's not that easy; the O2 sensor is the last sensor in the chain. It measures the amount of oxygen in the exhaust and compares it to the amount of oxygen in the atmosphere. The only way to get around the oxygen sensor "problem" is to modify it's signal in one way or another. The simplest I've found is the EFIE. Another one (though much more expensive) is the O2ptimizer that comes with the HAFC kit.

I would assume, however, that DV has the equipment to be able to tune to whatever air/fuel ratio and ignition timing that he wants; if that is the case, no external controllers would be needed. Otherwise, you'll have to add the price of an EFIE (or a dual EFIE if it's a V engine) to the install.

I believe he has been taking the downfalls from other electrolyzers and improving upon them on the bench; his unit has a good power-to-production ratio. However, as I've stated in most of my previous posts, more is needed than simply injecting hydroxy gas.
