So am I every time I twist open that valve.

I have a little surprise for you: That ROF wasnt max ROF. The valve was about half open and the tank was on about half the max pressure.
Though at some point the valve will go farting instead of making true cycles.

I explained it in the video, but I'll explain again for you:
Air goes into gun -> pressure goes up
Pressure goes above popping pressure -> popoff valve opens
Popoff valve vents air to the atmosphere (fast!), pilotting the QEV -> QEV fires
Pressure drops -> popoff closes
gun gets refilled

Access to a machine shop. I has dat too.

Oh and you guys should see that vapor cloud when going full auto from the fire extinguisher (the FE is now called tnak btw). I will pay special attention to that when recording the video tomorrow.
I'll join forces with Psy and we'll put his exhaust system on Porter...
