This thread has become even more active lately!
Yes, you do get a good amount of water from the exhaust; so much so, that it can cause rust to parts that are not heated -like a throttle body. I had run a copper line from my exhaust to a bubbler, but never gained much, if any pressure from it. The setup is still there, but disabled for now.
Buzo: Great work on the optimizations! I am really impressed with how detailed your results are. This is what some of us HCS users have been waiting for! Keep up the good work. If I were you, I'd try the cracking chamber that was mentioned earlier, using either the sanding disk or the spark plug ceramic. You could then try both, to see what happens! Do this before trying the water bubbler.
Also, I run HCS through BOTH my carb's ported vacuum port (venturi) as well as my PCV connection. That way, I am ALWAYS cracking with HCS!
I spoke to someone that got great results from HHO with a similar setup, using two reactors -1 that is always on, and another that works with the gas pedal.)
Persistence: I have a car with NO computer (for now). I can control the fuel ratio at idle with a thumb screw, but I'd have to change jets to reduce the fuel during acceleration.
I am able to reduce the amount of liquid gas used for idle by substituting HCS -but only to a point (almost 50% less).
My episode begins here:
My wife and I set out on a trip to the rural areas this weekend. My car had been smoking ALL week long, and I had plans of putting in new plugs (denso U-groove) for the long trip (60 miles each way) right before leaving. I thought that I would need the extra power, since at least 1/2 the trip was up and down steep hills. The night before the trip, I re-fitted HCS with dual bubblers for my PCV, and a single for my carb's vac port. When I drove my car, the smoke was SUBSTANTIALLY cut! Also, the difference in power was easily noticed! I was happy with the results. I didn't connect a water bubbler, since it cleans the engine, and the mechanic said I should let some carbon build up to combat the smoking of my old engine. Anyhow, I thought to myself "I can't wait to see what happens in the morning when I change the plugs!"
Morning came, I changed the plugs, started the car, and all was well! We drove off, and power was there, then a few seconds later, the car turned into chimney! There was so much white smoke behind us, that you could not see ANYTHING through it. That continued for about 1 mile, during which it tapered down and disappeared. I guess it took a mile for the oil to reach the plugs. After that, it was nice, until we got to the hills. This is where I started to see more problems. When we hit the hills, the car started to lose power, and let out blue smoke -but NOTHING like the white smoke before. This was tolerable, but going 30 to 50kmph uphill (about 20deg incline) was not! When we got to the 30 degree hills, it was worse, 15-25KMPH. The speed went down to almost 0KMPH when we hit the 40deg inclines! Yeah, these hills are serious, I know, but other cars handle it well. It drank almost .75L of OIL to cover that 60 mile drive. Coming back was much less though, since it was 90% downhill (very very very sweet, by the way. Unless you scare easily! My tires started to cry a bit, lol)
After asking around, I think that it may be either a transmission or a compression problem. Either way, it would involve a ton of work again, so I asked my mechanic to find a 5a engine with a manual gearbox, so we can get rid of the problem, once and for all. Oh, also, I made the mistake of filling my diff with 80/90 gear oil, before finding the car's manual, which asks for Dextron II (ATF?) in the differential. That should not make much of a difference though, right?
Anyhow, the new engine will use a computer and more gas, since it will be bigger, so I really need to see what the optimal HCS setup is.
Btw... my mileage for this pedal to the metal hill-climb of a trip is 25MPG. Base is about 25.5MPG I think.
Without the HCS, I definitely would have cried! I'd love to attack those hills again with a different engine and a stick!
