This is a very common question that we get every day. We make 4 different sizes to make the choice easier. General rule of thumb to choose the right size HHO kit, is based on engine size.
There is some flexibility in the choice. We have found you Can upgrade one size, but not not two. SO if you have a small 4 cylinder engine for instance, and you want to add a larger hho generator, you CAN upgrade one size to an 882 (if you have the room and the budget), for a bit better results. But any larger, you wont see any extra advantage.
If your car has a Turbo or a supercharger, you are packing as lot more air in the engine, so we find it best to upgrade to the next size hho kit.
Our HHO Generators are completely unique compared to any other systems sold today. Each cell is individual and separate from the next one. Why does that matter?
Well. look at the 883 pictured here. There are Three cell stacks and four electrode connection terminals. Each stack is separate and individual from the next one. The water flows into the bottom hose barbs, and the saturated gas rises up out of the top ones.
But here is what sets our units apart from others: By disconnecting the power to any one of those terminal connectors, that cell stack stops working, but the other ones continue like nothing happened!
Let's say you have a 6 cylinder car or van, and are thinking at some point you want to buy a bigger vehicle. You have room for the 883, and decide to get it, and just leave one of the outside terminals disconnected until later. You fire it up and it works just like an 882! Maybe you are hauling heavy equipment or a trailer, so you hook it up when you are hauling and unhook it later.
You Cannot do that with a normal dry cell - because the water flows through all the cells. But you CAN do it with ours- now you can customize and custom tune your HHO kit for optimal gains and power.
