pie x r squared
The math works out to nearly 4x (3.69) the volume increase of 0.065 to 0.125
Martin Meinhardt (the original maker of the rotary valves that Premacon copied) does offer a larger valve, though I don't know how much larger. Fumotec could get it for you. I could nail the info for you, if you want?
Carry on with your version, it'll be exciting to see you accomplish this too.
