So, I was recalculating last night, and 6 cu ft /min still holds true, as that is the volume of each cylinder. The engine's efficiency coefficient is a different story. I use cu ft/min as the engines I deal with rate the carbs, fuel injection systems, manifolds, all in cfm.
Visualizing this, is pretty close to a 2.5ft (lwh) cube of air every minute. I guess its not that bad.
My first goal will have to be 6cfm of hydroxy then.
Required hydroxy to run 2.5L 4 cyl

There is also a Huge Difference Between the amount of hydrox needed to obtain 2000 RPM in a No Load situation Verses a Full Load.
I'm Not sure if the numerical figures above take this into account.

Come on people, this discussion pops up over and over, and never fails to divide people and slow down progress.
Do you all really think that calculations based on BTU or comparing to gasoline is really going to get you anywhere. This is the EXACT SAME process the naysayers have been using for ages to keep others from trying. Just build it and do it, it's just that simple. Hydroxy gas is not gasoline, and it is not H2. It has its own unique properties and energy characteristics, that are not found in the texts. Tank hydrogen has a predictable energy pattern, since it is the lowest energy form of hydrogen there is. WE ARE NOT DEALING WITH TANK HYDROGEN
Jeesh, give it up already and just get on with the experiments.
Oh, and the 2 LPM "barrier" mentioned? Since when? I have produced flow rates too high to measure with what equipment I have, and have not consumed kilowatts to do it. 15 to 16 LPM just with straight DC in a single welder sized cell stack unit running on an inverter.

No progress being slowed down here. Besides, the purpose of my post was to get a general and mathematical estimate on how much gas is required. Saying that a certain volume of gas can't be produced in a minute is a whole different topic, and should be posted on a new thread. Thx.
Bzzz...
