22cal performance Q, need input

[Racing]

K guys.
Currently working on...



...this. Which is an Aselkon MX-10. In short a 22cal regulated gun on a 550mm/21,5" barrel.

Have opened her up port wise. Run a stiffer HS, as in a dual setup which is.. way stiffer vs stock but still FAR from "insane". Hammer weighs a hefty approx 80 grams stock, have gotten that down to approx 50. Runs harder on lesser weight.
Have added a MASSIVE plenum to it, and i mean absolutely MASSIVE. Run a 2mm stem poppet.

What should i expect out the snout at 150/170 and 200 bar respectively? Just approx numbers, cause i feel she´s foolin me a smidge here.

Air hog. Yeah yeah.. i´m all to aware. Power jumps like an easy 10-15J going from 25.4´s to 34´s all else being equal.

Would love to find a setting around 140-150 that´d hand me decent performance downrange on the stock barrel  (which shoots very very very well)..

That being said, i´ve been through it all. Several times, and it STILL just doesn´t compute to me. Exhaust is ported as is barrel inlet (for flow) FWIW. No, not to break any records just to soup the thing up.

Currently seeing 90J max using 34s.

Ideas?

If you've ever shot an SSP pistol you can hear a definite crack in the report. That's the sound of the air flowing through the valve breaking the sound barrier. Nothing else in the gun is moving that fast. The solution is probably in the porting.
