Hey guys…just an update. I got my HHO kit this week and am going to install it this weekend. I’ll let you know the results. I’ll be getting the remap later this month, but want to see what results I can get, if any, right away.

Also, I was wondering if any of you have tried the O2 spacers and was wondering if the results from these are anywhere comparable to the sensor remap…if they work at all.

If you guys haven’t googled smacks boosters you might try it. It’s my prototype for my ‘01 Forester.

Hey Matt,

The O2 remap is pretty important.

We are going to put the system on the passenger side inner fender just behind the bumper. And then have a tube stick out to add water.

This will keep it close to the intake.

I still haven’t decided on the canister yet but I am leaning towards a hollowed chrome steel hydraulic ram off of a large piece of equipment. Should be able to thread the end and build a cap for service and it should be bullet proof.

hey,

I am working on getting an HHO system in my 95 legacy. I think I am going to install without the 02 remap to begin with to see what kind of results I can achieve.

Space is a problem I have run into on my car. There is ample room in front of the battery, but I don’t want it to be so far away from the air intake. Let me know if you end up starting on a car with abs.

I found some small nalgene style bottles, 500 ml, that I am considering to make my generator out of. I would put two in a series if I go that route.

Igor,

I plan on the O2 remap.

But here is the thing, as far as the energy used that is being missed. There are things that can be done to the vehicles electrical system to decrease amperage draw to copensate for the amperage draw from the HHO generator. If I have a 85 amp system and I install led bulbs that use less current, only run blower motor speeds 1 to 3, Install smaller wattage head lamp bulbs, etc. I wont be adding enough electrial draw to affect the fuel economy of the Subaru with the HHO generator running. I have already installed the Led bulbs, less wattage headlamp bulbs, and have measured the total amperage draw before and after and have decreased the draw by over 15 amps.

This is what drew me towards a boost system. I know how to shave amperage to save electrical load.

I have read all of the theory about the amount of energy used versus the energy produced. But by increasing economy with HHO with out increasing overall petro fuel consumption is obtainable in my opinion. But time will tell.

Thanks for your Interest, and keep me posted on your Legacy project as well

Hi I also plan to add HHO gen to my Subaru 2002. Unless you have Joe or Stenley Mayer Cell or something better you can’t produce more energy burning HHo then spend on it’s generation. But as I researched as you don’t gonna power your car exclusively on HHO you don’t need a lot of HHO so 5 amp about 50l/h HHO generator should be enough. So you don’t need to change generator. More over If you put too much HHO MPG will drop back. so there is a kind of optimum for certain engine size.
Also you should tune O2 sensor to compensate for HHO addon. I have a few book from on DIY setups and explanation how to tune it. I can share them with you.
