Does anyone here have or had or knows anyone who has an Turbo XS RFL BOV? I've heard of boost leak issues with it, but I've also heard that you can get some sort of washer from Turbo XS to stiffen the spring and hold more boost . So if anyone can help I'd greatly appreciate it.

Thanks.

 

Found this in the BOV testing post.

I played around with it on a TurboXS H34. The H34 has two ways to adjust the load on the valve: you can add washers behind the spring to preload it (like crushing) or you can swap out the spring. When you receive the valve it comes with some washers to do that with, but no adjustment springs.

I went back and forth with Mark McGovern of TurboXS for a few weeks trying to get mine to work well. Went through four different springs with different windings and lengths before finding one that worked well for my application.

 

Washers go inside the BOV itself in front of the spring. You can physically see the cut out. I had their Type H for awhile on my WRX, but it hindered performance, so I pulled it.

 

Thank you for your help, I have decided to try it out and if things dont go well i will just sell it and put the stock one on.
