Everything is great accept for the injectors... I've looked at many different cars, Dodge neon, Astro Van,, Old For Escourt, "the best" and cavaliers... Most of the injectors have 4 very small openings at its tip. Only on the ford escourt you can tear the 4 small holes off to reveal an opening of 1 mm. The other injectors are made to where you cant really remove the small metal that contains the 4 holes.

I cant seem to get much gas threw the 1mm hole, i've tried 3 injectors in parallel to get 3mm but still i didn't see it improve the flow rate. My Hydroxy tank is only capable of 4 PSI before bad things start to happen. So right now,,,, its a no go.

I might look into some electronic solenoid valves,, 37 ms comes and goes very very quick.

Can you separate your HHO Production and delivery systems?
Perhaps a 10 psi pump on the end of your bubbler pump through another bubbler (to protect your pump) and have the tubing to the injector about 2 -3 times thinner (inner diameter, the wall thickness will need to be able to stand the pressure) this should compensate for the pump... kind of like cramming your 4 psi into a smaller tube to make the pressure higher.

Using an injector implements another safety barrier in your installation. I haven't heard of any of the newer cells getting destroyed flashbacks because of the introduction of bubblers. But what happens if the ambient temp under the bonnet is enough to evaporate your bubbler... and you don't notice. These sorts of things need to be thought of and i think that with and injector style apllication you can get greater precision in your HHO applications then just wofting amounts in and hoping that the acceleration lag on your cell is small enough... i would prefer to have a better system that keeps all of the ratios for combustion at a constant no matter how much i feather the throttle. But that is me.

I'm sorry, but Why the injector for the gas?

The only time I ran a small ICE on HHO, I found it simpler to just use a small tube from a valve right into the intake port.  The valve was then the throttle.  This actually worked very well, though the linkage was a pain to get free enough to operate from the engine governor.  I had more trouble adjusting the timing, and used a much more complex method than yours for that.

Now that I have seen your intake valve switch, I mat change to using that as a timing reference, as it's easier, but there is no valve operation near TDC, so I just realized I have to stick with the hall effect.

Little Question?  Why do you think electronics would be too slow?  A basic Radio Shack transsitor would be plenty fast and you are using a driver transistor anyway?  A Hall Effect transistor, mounted inside the inspection plate near the valve spring would be a faster switch, with no mechanical wear.

Just my curiosity getting the best of me, as the work you have done and the pictures provided are great!

(I'm sure your aware that the injectors flow rate is carefully metered from the manufacturer, because they use the "ON" time to meter the fuel.  This might limit the max amount of gas at lower pressures.)

It was and efficiency test for the 1000th time. The theory is cut the gas off when its not needed, i cant explain this again. The valve stays open for 37 ms on idle and your flow rate is normally 166 cc's a second. SInce your only inhaling a total of 250 ms out of one second, but yet you're producing 166 cc's a second,, should i go further?

It isn't that the electronics is to slow,,, IT IS why would you want the injector to be open after the intake valve has closed lol. There's simply no need for electronics. The injector opens with the valve, and it closes with it no matter the rpm. It would be nice if the injector could open before the intake valve opened. But you see why electronics isn't needed, "computer delays that is." No room for a delay because the valves already shut...

And yes, the injectors have a thin metal layer over their tips containing 4 very very small holes, this "busted the gas into a mist." if you remove this thin metal layer containing the holes you get a nice 1 mm exit hole. Still not much good since you cant hardly get anything much to flow threw a 1mm hole. So this leads you to solenoids... Then you have brought up the fact that under a load what happens when you have to control the Spunk. Which makes this setup look shitty.

Yah,,, things dont look good for this setup even if the numbers do show efficiency is there,, i don't think i'll go threw with it after today.
