The new Ball valves looks great, but does it take longer to vent your chamber through the 1/2" nipple after the 1" BV?
P.S.
Has anyone ever tested the burst pressure of galvanized steel?

I ma have misinterpreted this, but DYI said he was playing around with GasEQ and he saw that oxygen mixes do not outperform air mixes with an equal volume of fuel.

correct, until you approach the speed of sound in the burning propellant gas.
The air powered version also heats the ~80% of air that is nitrogen, creating more pressure.
with equal volumes of fuel, pre-ignition pressure at 5x is 4 bar an 0 bar respectively. even with 1/4 the temperature increase, you will still get equal pressure.

I haven't been able to ask if there have been any recent changes since the chat has been down, so is it still in the same state as last seen? Also, you've kind of explained it before, but I still don't understand your vent valve..

I'd love to hear all about this, but sadly I guess this falls in with the special projectile SWIM's making.
