MBC lines

[HiImBrian]

Latley I have not been able to hit full boost. I should be at 21psi but I'm gettings stopped at 16-17psi. I am going to do a boost leak test tonight when I can borrow my buddies air compressor, but I thought I'd check all my lines first. Is there anyway I'm running off my 1 bar wg spring? Are these lines ran correctly or is there a different way to run them all? Thanks

Your routing looks correct.

Is there any other way of routing it? I thought a friend of mine told me a while ago that I could just connect a few lines together or run my mbc to my turbo or something.

My turbo has a place to hook up the vacuum line for the pressure source. I have like 4" of hose on either side of my boost controller, it sits only a few inches away from the turbo and wastegate.

That's what I'm thinkin about. Where do all your lines run to then? My nipple on the turbo is tied off (like that when I baught it) so if I were to use that as my pressure source, how would I run the rest of the lines? And is there any benifit to running the lines off the turbo?

Here is what mine looks like. I believe the benefits are less boost spike, maybe some other things too that I can't remember.

Then for the BOV just run a line straight to the intake mani.

Clean your mbc out, running off the compressor housing will allow the lowest boost possible. Most people run the line off the intake manifold like you have it now.

I used to run one pressure source for both the BOV and wastgate but was having some issues with my MBC also holding boost. I ran them independently and that fixed the problems.

Awesome, I'll go buy some new lines and switch them around and see if that fixes the problem.

Fixed it! I ran the bov to the intake mani and the mbc to the wg and to the turbo. Thanks slowboy! I actually had more than enough line the way it was so I just switched em and now she bangs nicely.
