Bit of an update ... here @ 1 year later and a few bits of BREATHING mods just done.
Early on when getting the Airwolf had converted it from .177 to a .20 cal while also opening up the ports a bit to @ .152" in transfer size valve to barrel. The power results as stated in the above looked like this
Level 12 = 1035 fps for 31.6 ft lbs * Max power with a barracuda match 13's
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So today I took the rifle back apart going into the valving to see how much meat there was to open up the ports getting a higher overall power being the Heliboard allows such a range of power settings.
After measuring came to conclusion ports of @ .170" could be made, poppet stem thinned a bit within valve throat etc ...
So the .170 spec transfer mods got done, new o-rings threw out and reassembled.
H&N barracuda now shoots at @ 1100 fps on power level 12 for 35.73 ft lbs ! Which picked up @ 4+ ft lbs with the larger ports.
With the HEAVY Sam Yang 23.7 pellet previous ... 875 fps for 40.28 ft lbs where now they are moving out at @ 898 fps for @ 42.4 ft lbs.
All said and done running differing weights in the gun at MAX power, the standout was THE New ... JSB .20 heavy 15.89 and some resized .22 Hades 15.89's BOTH moved out at @ 1065 fps making an astonishing 4O Ft Lbs Power !!
Now granted I'm not going to run at this power level and actually have found the JSB 13.7's at power level 8 ( Of 12 ) makes @ 920 fps and yields @ 180 +/- shots on 230 bar fill in 500cc tank.
What a set up !! Ultimate Air Wolf indeed
