gutbusterman Posted August 17, 2008 Report Share Posted August 17, 2008 I wrote a post about a month ago about my 850R not boosting. Upon some further research here on Volvospeed (thanks all), I found some ideas to look at. #1 on my list was the CBV-compressor bypass valve. And whaddya know-crap. I'll post the pic. I tried to contact Quickbrickmotorsports for the replacement diaphragm, but they never got back to me. Fortunately, the guys at Forge Motorsports did get back to me and now I have a blocking plate/BOV conversion. After I installed the plate/BOV, I still didn't have any boost. WTF. So I pinched off the wastegate and voila! I have boost. So, that tells me the boost controller is junk, so I am going to install a MBC. Any suggestions on brand? That BOV sound so cool, now only if the car looked that cool. I still intend on checking the wastegate pivot for alignment, and I am going to install a boost gauge so I know what I am getting. Thanks again for all your help. Link to comment Share on other sites More sharing options...
