Siegetek 14.09:1 gears arrived last week... Team had a tech day on Saturday so I pulled apart my gearbox and dropped in the new gears + reshimmed and relubed everything.
The air seal was improved with the reassembly, noticeable by a small bump in FPS (back to 413 from the 5 FPS loss with the new hop up) and a small consistency increase (+/- 3 FPS now vs +/- 6 FPS before)
To combat the increased speed of the gears I moved the bearings from the spring guide to the rear of the piston, adding weight, and used a plastic spacer in place of the bearings on the rear of the spring guide. RPS increase is minimal at ~1.2 RPS with the box mag and 2.2 RPS with an M4/M16 STANAG. This translates to ~22.5 RPS with the box mag and ~23.5 RPS with a STANAG magazine. Given the huge increase in reliability I can live with the increase, which honestly is fairly minimal as I'll be using the box magazine 99% of the time.
Funny to put it in perspective though; 1 midcap every 5 seconds with continual fire lol.
