Stormrider Plenum Extension ?

[wll2506]

You guys that are way smarter then I am, what would a 1 in extension do to the pyramid regulator for this gun. as in you drop in a 1 inch extension tube and then the regulator to give the plenum more volume !! At a given bar (lets say 120) how much extra speed do you think I would get because of the extra volume ?

I'm looking at the possibility of doing this !!

Are you looking for more velocity? If you pull the barrel and measure the port...then drill the transfer port and valve port to match the barrel, im betting you'll get a nice jump in velocity.

Already getting 885+ with an unregulated gun ...  looking to bring her down to 825-850 fps with more consistent shots and a longer shot string.

I've been following will. When regulated, you need to open things up and let it breathe. Your looking for more shots in the 850 zone, possibly a lower reg setting correct? The gun was built to give a bell curve. At a higher start pressure than you have the reg set. You now regulated it.  You need to open it up so it can give you the velocity and shot count your looking for at a lower pressure. It needs to breathe.
