GREAT WORK Tim!!
I ordered a new valve along with a new gen 2 bolt a couple weeks ago and its still sitting here untouched waiting to see what you came up with, and I knew you would get there. I guess its time to order that regulator now!
When you get a chance how about give us a summary of what you did?

Well done Tim, that's the string I dream about, but can not come close to...yet. Keep up the fantastic work.

Well I gave my 60fpe goal a try and failed. Gun sounded like it was just wasting air and the shot count proved it. Don't know what to say there. I am disappointed but there's gotta be some other trick to get it. I like full bore porting but "dang", that's gonna be hard to work out chief.
I am thinking a 24" barrel will do the trick without full bore porting and possibly bring that 50fpe/40shot to a new 50/50.
3000psi to 2000psi - 16 shots with 33.95's. Dropped hard off regulation (2050/2100psi).
Full string:

Ran a comparison from before to now.
Before was stock huma reg (with gauge port) with .196" porting through and through
vs
.22 porting through and through and 40cc modified huma (with gauge port).
Hard to tell which modification (porting or larger plenum) made the best impact. My guess would be the porting.
Good interesting stuff here because to take this platform further (regulated), porting has to be full bore and stock HPA side has to be larger for shot count UNLESS, a longer barrel is introduced. You mine as well not call it a Mrod anymore.
