I don't care it sticks out the stock (longer)..
so I shot a few across the chrono to see some effect of the plenum at about 25cc.3500 psi fillregulator at 1600(110 bar)ports drilled .187 no other power mods.No hammerspring washers, actually faced off .006 less than originalBarracuda match 21.14First shot reg crept to 1800877Next 20 at 834 +-5for 32.6 ft lbs.Looks like the plenum will provide positive, results.
plenum guage.
Plenums will be available soon. I do thing right, no necessarily fast. There is a lot to consider, I do not want to overlook anything. As far as powering it up and seeing what she'll do. Tuesday....I'll see what it does with the 10mm thread, .205 port. I'll go to 1/2x20 with a .3 port if it is inadequate for the insane!!
Mine appears to have a leak. 1000 psi over 2 days. Not sure what to do. Wait for larger plenum tear down and reseal. Don't really wang to mess around with sending back.
I just saw PA has the Aspen listed in .25 with 800 FPS claim
Probe and barrel swap. fpe should be the same if not more due to the bigger bore.
