All I know is that everyone I've talked to that has had a device similar to this installed has reported positive results that even taken conservatively show promise. Bottom line is that internal combustion engines are so far from efficient it's ridiculous. I think instead of immediately storming this thread with naysayer posts, how about something constructive and supported. Yes this vehicle does tip two tons on the scales, but when a 550 HP V-8 beats us in mileage, it means our engine just aint doing something right. Everyone I mention our mileage to seems to think it doesn't sound right. So if injecting hydrogen and oxygen into the air charge makes for more complete and even combustion, then that makes sense to me. Look at nitrous oxide. It sounds unreasonable that throwing some "special gas" in the air charge could increase horsepower 50-150%, but it does. It's really not that unrealistic to say that changing what the engine breathes changes how well it works. How well does your metabolism work when you eat junk food vs. eat healthy-same with engines folks.![]()
