If you can return the kit and get your money back, do it immediately! That is doubtful though. EDIT:If you have the time and disposable income, it might be a fun experiment, and I could be completely wrong about its efficacy. I just have a lot of doubts. For further reading I posted a few links. If you bing or startpage or ixquick HHO scams (search engines I now prefer over others, and startpage, which is owned by ixquick, is enhanced by google in a more private way), there are forums that discuss this stuff. Real, independent testing using controlled and scientific methods have not found these things to work.http://forums.genvibe.com/zerothread?id=43884
, My thoughts on another post.https://secure.wikimedia.org/w...d_carh ... ometricMaf
and Map sensors are not detecting the hydrogen levels, so they are not adjusting the algorithmic programs, richness or leanness. The oxygen sensors have a too limited range of adjustment for the claimed mpg increases. If claims are that there is more complete burn and less emissions, then the o2 sensor would probably adjust to go rich, thus burning more fuel. Pre-detonation or knock sensors do not have the range to adjust timing advance either way for the large claim of mpg increase. There is nothing that is going to decrease the amount of fuel "stoichiometrically" that is being injected on every compression stroke with the addition of an HHO system. Within a static and dynamic compression range, compression/timing and fuel/air ratio is set at a level not engineered for any big changes, such as with forced induction for example, especially without a different, tricked, or reprogrammed ECU/ECM.The engines are not designed for this kind of thing. The head, valves, pistons, rings, fuel injection (not being direct injected), oil levels, coolant system efficiencies, etc. are not designed for lean burn operation. The hotter running engine and heat soak is not engineered for lean burn operation.Compressed fuel and hydrogen like gases have different values, properties, flash point, etc. and do not mix or change states, bonding together, and then combusting at some miraculous same rate. Combustion chambers get pretty hot, even before spark plugs fire. Spark plug heat ranges and gaps are set for specific operational levels. These things are supposed to be for mpg, not some performance enhancer such as NOX, and most people that are trying to get better fuel economy value longevity and reliability too.Best and worse mpg guess, + or - 2 mpg, averaging no gain. Best case scenario, a little more power at full timing/compression with this so-called complete burn (acting hopefully like higher octane without ethanol's energy loss and no pre-detonation or retarded timing), so ya become a little easier on the throttle. Perceived benefits, real or imagined, might cause most, if any mpg gains. I had to put on rose colored aviator goggles to get there though.Personally, I think you will lose mpg when considering the extra drain on the alternator, and the requisite increase in rpm's, especially at idle to keep up. Kind of like having the compressor on, especially the defrost in winter with fan on high and the auxiliary electric heater running also, if you have one of those model Vibes.Worst case scenario: Major pre-detonation and low performance, and that is if you are lucky. Hopefully pistons, valves, and other parts hold up, while possibly running lean, too hot, and overheating. Warped heads and gasket leaks are a possibility. Hopefully there are no leaks and fires. I always like to put a potential Hindenberg under my hood where it is safe. I hope it is not a glass mason jar Hindenberg. I jest a little, but seriously, be careful.Edit:The relatively low volume of hydrogen that can be produced in ratio to the air volume of the cylinders at rpm's might be the only saving grace for the engine. Tricking the engine into a run lean state, though, is highly unwise, and also is probably the only way you will ever possibly see any mpg gains.Raw material costs and replacement/replenishment probably will make it cost prohibitive anyway. then there is any added weight.If this HHO thing is so easy, legitimate, and cost effective, all car companies would be at least offering it as an option. Power generators would have em. lawn mowers would have em, etc. These are just some of my rambling thoughts on the matter and I might be completely wrong.I am not a certified mechanic, physicist, or chemist, I just play one on forums.Good luck, I hope you are successful or get your money back.
