Does the hydroxy delivery hose size matter?
A fellow experimenter used a long 1/4" hose on his 6 LPM booster with
apparently no delivery difficulty.
Has anyone tested 1/8, 1/4, etc. in order to determine the minimum
effective tube diameter for 2 LPM?

I am still trying to get up to 2LPM... Here is my current design based on ZeroFossilFuel's VSPB design... I would just love to see the 2LPM mark.
I am going to use my 1/4" inside diameter hose with it. It is what I am currently using on my Smack design with .750LPM. Even the port on the Cold Air Intake is set up for 1/4" fitting, so that is what I am going to stick with. If it turns out to not be enough... well then back to the drawing board...

What we need here is some math formula's to convert LPM to a PSI pressure. We could then determine max PSI for each hose width?
Hmm, but thinking about it, the PSI would vary and be a factor of LPM vs hose diameter.

Of course if you increase PSI you also increase the danger of explosion. Not that we are anywhere near that point, but food for thought.

I can concurr with that observation. I was told a 1/8" hose can
deliver 10LPM of most any gas without difficulty. So I'm fine with my
1/4" hose.

Dia & length cause back pressure 10 LPM through a 20' long 1/8" ID hose would cause a lot of pressure. That pressure would lower your boiling point, and you may just be getting steam and no HHO. your water would be gone very fast.
1/4" tubing is a good for just about all HHO uses.

I disagree.
More pressure INCREASES the boiling point, it does not lower it.
Think "Pressure Cooker".

Sorry - you got that one wrong
Increasing pressure will raise the boiling point in the generator (the same as putting a pressure cap on the radiator).
I think that this is a good thing - hooking up to a vacuum line and lowering the pressure in the gen. at idle seems to cause more empting problems in bubblers and gens. I think this is because the generator flash boils when it has been running at some pressure for a while and then it gets a sudden low pressure when you take your foot off the gas.

Your right my Bad. higher pressure = higher boiling point thank you.
