BEFORE GETTING STARTED

Before we get into choosing the best HHO System Kit for you and your vehicle, it's best to have at least a basic understanding of what HHO (Browns Gas, Hydroxy gas, etc) is, and how it actually works. You'll also want to have a basic idea of the size system you might need for your vehicle, too. If you've already delved into research on this amazing technology and just need help fine-tuning your System selection, then we can move right along to the next section! If not, please take a few moments to review a couple of our Knowledge Base articles:

There is a plethora of HHO information, though, in our Knowledge Base. And, much of it will be linked to you throughout this guide. We encourage everyone to read them, so we can all have full confidence in the installation and usage of one of our HHO Systems.


Which Type of System?
Wet Cell or Dry Cell?

There are two types of HHO Systems that we offer: Wet Cells and Dry Cells.

The Wet Cells are the more basic jar-style HHO Generators and are going to be a more affordable option to getting started with HHO. While they may have higher maintenance needs, they are more cost-effective and can get the job done. But, just because they are less expensive, doesn't mean they are any less the contender. We've taken the original Water4Gas design, and put extra time and effort into making sure that these generator cells are constructed with the highest quality: both in materials and craftsmanship. Precision cut-and-notched Plexiglass, wrapped in custom-twisted 316L Stainless Steel Wire (0.045" diameter), with stainless steel hardware both above and below the lid for cleaner and more efficient Wet Cell.

The Dry Cells are a heavier-duty closed-system design, affording them a longer life-span and higher overall durability. They are constructed of the same grade of stainless steel as theWet Cells, only as precision-cut plates sandwiched between two marine-grade Starboard® plates. They also are less maintenance-intensive. The Complete Dry Cell Kits also include a superior Constant Current Pulse Width Modulator (CCPWM - a more in-depth look at the PWM in this article, here). Basically, though, the CCPWM allows for the management of the system's voltage, amperage, and duty cycle. It affords a way to manage thermal runaway and eliminate overheating, and gives you the ability to set and monitor the system vitals with the LCD Display Controller. But, of course with these superior features and electronic components, comes a little bit higher of a price tag.

Overall, either style hydrogen generator system will work for you, and you can achieve better fuel economy regardless of the type of system. It just depends on what you are more comfortable with. It generally comes down to budget and preference, and we stand by all of our products for quality and craftsmanship. You can also get a little more info on the differences of the two types in our article, here: Wet Cell vs. Dry Cell.


What Size System is Best for My Vehicle?

You'll want to get an appropriately-sized hydrogen generator system for your vehicle's engine. This is generally based on how much HHO gas you'll need for optimum mileage gains and performance on your vehicle. Now, this will vary from vehicle to vehicle, but we have some handy guidelines that you can follow to pick the right size system.

For our Wet Cells, we've designed them to be modular, so that you can provide the right amount of HHO with the right number of Cells, and carefully crafted electrolyte ratios to achieve desired amperage levels and overall performance levels. Basically, you'll want to go with approximately one Cell per liter of engine size (rounded up) for best results. You can also look at it with respect to how many cylinders your vehicle has, too:

  • 4 Cylinder Engine? Then you'll most likely want the 2-Cell System.
  • 6 Cylinder Engine? Then you'll most likely want the 4-Cell System.
  • 8 Cylinder Engine? Then you'll most likely want the 6-Cell System.

The Wet Cell systems are available with several different Hook-Up Kit options, depending on your wants and needs, and your vehicle type. The Hook-Up Kits all include necessary electrical and vacuum items and fittings, for attaching the system to your vehicle's engine and powering it up. We have Essential Hook-Up Kits, which come with the basic parts for a single supply hook-up to the engine's manifold vacuum line. We have a Premium Dual Supply Kit, that comes with the necessary parts for attaching the system to both the manifold vacuum line and the air intake, along with some extras that make maintenance easier. A "Dual Supply" allows for optimal HHO delivery to the engine, and is our recommended Hook-Up Kit. We also have a Single Supply Kit that contains all the Essential Hook-Up parts, along with some extras for making maintenance easier. Then, there is our Diesel Engine Hook-Up Kit. This Kit contains the necessary parts for making a connection to the air intake of your Diesel engine, and also comes with the extra maintenance items.

For our Dry Cells, we have two different sized cells that will take care of your standard passenger vehicle: a "single stack" 7-plate Cell, and a "double stack" 13-plate Cell. You'll want to choose the DC3000 for engines up to 3.0L in size, and the DC7000 for engines up to 7.0L in size. If your engine size exceeds 7.0L, we can also do a double DC7000 set-up that will accommodate that larger engine. We also have available, a DC25k Cell for larger commercial engines up to 25.0L in size, such as a Semi truck, or even a commercial fishing boat. If you're finding yourself with an engine size that is just on the cusp of those size references, you can most likely round to the nearest Cell size, and go with that. For example, if you have a 3.5L engine, you could still go with the DC3000 for optimum gains without having to jump all the way up to a DC7000. But, say you are over 4.0L, then you'll most likely want to get that DC7000 to make sure you can produce enough HHO without over-amping the Cell. All the Dry Cell kits come with the necessary Hook-Up parts to accommodate any engine style.


Electronics: Do I Need an EFIE or Other Enhancer?

Many vehicles are factory-equipped with oxygen sensors. These sensors tell the ECU the condition of the emissions leaving the engine and going out into the air. However, these sensors tend to disrupt the effectiveness of HHO gas, by thinking it's a lean air/fuel mixture. The ECU then tries to add more fuel to compensate, which is counter-productive to the benefit of HHO gas. The solution? An Electronic Fuel Injection Enhancer (EFIE). These devices are designed to allow you to adjust/manage the sensor's signals to the ECU, so that the HHO gas can do its magic.

We recommend one of these for vehicles with O2 sensors, for just that reason. Now, there is a chance that your vehicle will adapt to the HHO just fine, without any electronics enhancement, at all. But, we've just found that you get the most benefit out of the HHO gas, when treating the emissions sensors so they "play nice."

There are four types of EFIE devices, each are vehicle specific to a particular sensor configuration. You can read more on what an EFIE is, in our EFIE Information article. Below are the 4 types, though, which you can click the links to open a window for each listing in our store, and read the full description of what each one is designed for:

  1. Dual Narrowband EFIE - This device is designed for vehicles equipped with up to 1 digital Narrowband-type oxygen sensor that is upstream of the catalytic converter, and up to 1 analog Narrowband-type downstream sensor.
  2. Quad Narrowband EFIE - This device is designed for vehicles equipped with up to 2 digital Narrowband-type oxygen sensors that is upstream of the catalytic converter, and up to 2 analog Narrowband-type downstream sensors.
  3. Dual Wideband EFIE - This device is designed for vehicles equipped with up to 1 Wideband-type oxygen sensor that is upstream of the catalytic converter, and up to 1 analog Narrowband-type downstream sensor.
  4. Quad Wideband EFIE - This device is designed for vehicles equipped with up to 2 Wideband-type oxygen sensors that is upstream of the catalytic converter, and up to 2 analog Narrowband-type downstream sensors.

You'll want to pick the EFIE device that is compatible with your vehicle's oxygen sensor configuration. You can view all of our EFIE devices, by themselves, in our store here.

But, wait, what if my vehicle isn't equipped with oxygen sensors? Not to worry. We also offer a Universal Frequency-based MAP/MAF Enhancer (that also can control voltage-based sensors, as well). These are more geared towards vehicles with Diesel engines, and even some carbureted engines. But, you could need one of these for your Gasoline engine, instead of an EFIE, or even in addition to an EFIE. Now, if you have a Diesel engine on your vehicle, there's a good chance that won't need to mess with any of the sensors. We generally don't recommend any enhancer for a Diesel engine, and to go without one, at first. If gains aren't being made, or the HHO is affecting the MAP or MAF sensor, then it's time to look at an enhancer for it.

How about if my vehicle isn't equipped with ANY sensors? Then, you're good to go with just a system; no enhancers needed!

If you're unsure of your vehicle's sensor configuration, we are currently working on adding even more informational articles about what the different types of sensors are, and also how to determine your vehicle's sensor configuration. They are available in our Knowledge Base. So, check those out.
