So after using one last year, I swear my WGDC increased by 6-10%, giving me a small boost leak. Maybe it didn't, but I wanted to create a better seal anyway. A gap is seen in the picture below.

I purchased weld bungs, only to find that there is no appropriate location on my Helix V1. A custom up-pipe also proved challenging due to spacial constraints.
So I designed some couplers to secure the bung outward, while simultaneously preloading the bung against the silicone to seal any boost leak. It was two semi-circular halves which also formed to the 2.5" silicone. So there I was in the machine shop, and after about 10 minutes on the mill, I saw the end of the ballscrew and then it struck me. I'll let the picture speak for itself.

5/8" e-type circlip. 0.048" thick, just enough to take up the slack.
As a sidenote, I'm sure the full pin clip would work as well, but I didn't have any around.
