I read most of this, understood essentially none of it
I'm not even clear what you gents are trying to do but it seems impressive
It's quite simple really,
The Throttle bodies get out of whack when someone thinks that's the way to set the idle speed, it throws the mixture out the window.
What we need to do is re-set the throttle stop on a messed with throttle body so it passes the correct amount of air.
If we have a good unit and measure the flow through that its a simple matter of matching the flow of the bad unit to the good unit
Since we have no way of measuring the air flow we use water, we don't need to convert water flow to air flow because for any given opening if the pressure is constant the flow will be constant also unlike air, water is very easy to measure by weight or volume/Time
This is something control valve manufacturers have been doing for ever, they talk in cV the quantity of water that will flow in one minute at 1 psi
In this case we just need to set a molested throttle body to flow the same an un-molested one, if they both flow the same quantity of water it goes without saying they will also flow the same amount of air.
In theory someone could take the numbers I found and make a rig to set his throttle body to match mine.
His rig could look quite different, it only has one important dimension and thats the height of water over the butterfly, the pipe diameter could be quite different within reason.
I spent many years specifying control valves for chemical plants, I'm just trying to find a practical use for that experience.
I only had one throttle body to work with, the one on my Griso which still had the original paint sealing the screw.
