throttle controled hho

Sorry for the snippy attitude. But for real. It's a dead end where you are going and it's been documented on this forum over and over, failure after failure. Even after modding all the sensors and stuff you may see a small increase in MPG but that can be illusive until a full 2 years of fuel consumption is recorded. Your biggest problem is heat. Heat is waste and causes the water to boil. And current causes heat, but, no current gets you no gas with electrolysis. Cooling the water will just add to the losses.

Your dry cell may be able to run a mower as it is but you will quickly find the motor won't be able to handle much of a load. Like when you cut thick grass. There are a few more issues other than heat and torque too. Any parts not stainless steel such as the exhaust will rust incredibly fast. And in the end you haven't really done much more than slap a few plates together and make an efficient water boiler that can start off making a bit of HHO.

How much of an increase in MPG do you expect to find? What are your goals towards alternate fuels?

i would like to double my MPG for my honda which is currently 26-28mpg (i have an older honda and a heavy foot)  but really im going to get what i can get and try to increase my MPG over time.

my initial tests and aim is to pull 15 amp or less and maximize my MPG from that.  i have looked at the math and understand that chances are my best effeciency is 2.6 watt per liter hour (or was it minute?) and at 12v*15amp = 69lph or just over one liter per minute.  this isnt much but if the science is correct about the burn of gasoline and hydrogen i should see some notable results after adding the O2 mod to my exaust (i understand this is my lean control)

and of course if all else fails i get a really cool torch

thanks for the input my honda doesnt really seem to have much of a computer that i can find. but it is one of the earlier fuel injected cars, i believe its a well its the older low throughput one what ever that has plenty of mods so im ok there, actually setting it up with the hho seems to be a daunting task which i will test on my lawnmower soon enough albeit my lawnmower isnt fuel injected but its better to fail with it then the car

Artic, how is your project going?

Not sure if you knew about it or not, just ran across this thread while I was trolling Google hits and thought I'd mention something. www.voloperformance.com has the FS2 HHO which will change your map in your ECU so that you can use the HHO more effectively. I'm about to install one on my 06 Silverado if they can answer a few questions for me, and also on the wife's 2000 Excursion (V10, 3gals per mile).

As for your original question in this thread, about the TPS trick. I'm entertaining the idea of running a "fuel rail" with hho with fuel injectors pulsing the fuel into the intake. Probably going to use RPM and TPS signals to control the PWM that controls the fuel injectors.

Just in case you've never heard about it. This was done a LONG time ago, and I ran across it about 10 years ago myself and inspired me even further, even though I was already on "fire" to get my vehicles changed.
