If you see my BOV, you can see tha needle is allll tha way screwed down, because of tha P/S res..

And because of all that, when drivin, barley buildin boost, my BOV cannot release fully, pushin tha air back into tha turbo. I have a video of it, but cannot figure out how to post it. When I build 14psi, its fine and releases, but Im not tryin to build boost everywhere I go ha.

Should I relocate tha res. or should I get another BOV?My dad has a FWD SR and his set up is like this.

Should I just do tha same thing, cause if Im gettin a new BOV, I dont wanna spend money on a new hotpipe, I'd rather do this. His pipe was just cut tha length of tha adapter flange pipe, and he used tha couplings and Tbolt clamps, and he runs 17psi daily, so should I be good?

Reliability issues?Im just wonderin.

This will probably be tha plan.

I was thinkin it woulda be a helllla of a lot cheaper if I just got a L shaped vaccuum thingy[Im sorry I cannot think of tha name], that pulls tha piston up in tha BOV so it woulda hit, but I still dont know if it would clear.

Make a new pipe to move the local of the BOV. Its not that hard or complicated. Or weld in another bov somewhere else and run two.

or cut your pipe on both sides of the bov then use couplers, similar to the 2nd pic.
