. Any guesses on the final fps @ 8 pumps?
Fps or Fpe ? Maybe a small nuclear boost.
I got my 392PA on 8 pumps getting 571 with the JSB 25.39 for 18.39 FPE. That explains why you need to get the pumps so high, increasing the volume inside the valve.
Somewhere around 900 fps would be great on 8 pumps

Without looking up the other thread what are the square orings for?
