Hey everyone. My vector was never a great performer out of the box but never had a chrono to confimr so assumed i was just expecting to much. Anyway As with all blasters did the standard oring and 1.2 spring treatment and was abit disappointing when i finally got a chorno and it was only showing 180ish fps. Chrono shows 280fps for a stock gen 8 with oring, oring nozzle, SS barrel and spring upgrade so chrono is definitely accurate.
I got started on tracking down the issue which is obviously a sealing problem. I added a double oring nozzle which didnt help, have added a SS barrel which didnt help, have changed the piston head to another plastic one i had laying around which didnt help. I ended up putting a Gen8 hardened return spring on to try and push the nozzle into the t piece better which also hasn’t fixed anything. I have tried 2 of the standard orange t pieces and both do the same thing.
When i blow down the barrel i am definitely loosing a substantial amount of air from the t piece area even with a fresh vector double oring nozzle and t piece. Has anyone had any issues with the nozzle not lining up properly in the t-piece? i have noticed that if i jam a screw drive up the feed port on the t-piece and give the nozzle a good wiggle around it will eventually seal correctly but then return to the unsealed position following a cycle.
Any one else had this issue and have a fix? im at the point where i think my only option is to buy a new gearbox as i think their may be a molding issue with my current box which is causing the cylinder head/nozzle not to line up correctly with the t-piece.
ATM i have to run an m90 spring to hit 220fps which is not right.
