Hi - I did a few updates on my .177 Notos - And unfortunately they turned out not like expected...
Huben dream valve + plenum
0,36l bottle
peek valve
I also ported the whole system:
1 marked in red - I drilled the bore up to 4mm (I did not touch any thread)
40 marked in blue - I drilled the bore up to 4mm
42 marked in green - I milled the bore up to 6mm (diagonal) - With the help of a 3D printed guide
Barel marked in red - I drilled the bore up to 4mm
I polished and cleaned everything...
After I reassembled everything with silicon oil and some new o-rings I get the following results:
Regulator set to about 2200 psi
Hammer spring screw fully turned in - so heaviest load
about 700 fps
about 11 fpe
I already played around with the PSI and the hammer spring screw but the above results were finally the best I could get...
I played also a little bit around with some heavier pellets and slugs - But this was worse...
Can someone please help me how you reached 850fps+ and more fpe? I expected more with all the porting and tuning.
If I do a shoot test with the JSB Hades (0,670g / 10,34 gr) at about 30yrd it groups perfectly - So I'm very happy with that - Only the power is not satisfying.
Thanks to all the Notos threads here with the good information and all the help that you already provided!
