  1. Focus ST Maintenance
    I have a boost leak because of my Boomba BOV not being fully secure and I cant tighten the bolts because they are stripped. So i ordered the GFB DVX BOV but it did not come with bolts. I believe I'm supposed to use the OEM bolts but i do not have them on hand. Does anyone know where i can buy...

    Hey, I just installed a Turbosmart bov on my 14 st and I forgot to put the bracket back on with the new bov, I’m wondering what this bracket does and if it’s important that I put it back on!? I included a photo as well! Thanks!

    Hi all, Hopefully this hasn't already been answered a million times. I tried searching and can only find people asking questions about how to run the BOV to the symposer delete but I'm looking for people who have already done this and have experience with how often a properly adjusted...

    Hello everybody, I’m looking for some help with an issue that has been bugging me ever since I added a Cobb tune with my turbosmart blowoff valve. I installed the BOV. It sounds great and everything but the moment I try to run a Cobb tune the turbo sounds get all wonky. It’s like a person...

    So I recently bought a turbosmart BOV and when I was finished installing it and looking for the vacuum line I realized that it already had a tial blow of valve. I bought the car and I never really knew what it had until I started looking around. So my question is can I run them both or do I...

    Focus ST Performance
    I'm not that versed in car upgrades and what everything does. I am looking for a Bov, but wasn't sure if I need to upgrade anything else or if it can be a stand alone upgrade (can't currently afford bigger upgrades). Also i saw online that "some cars have the mass airflow sensor (MAF) located...

    I installed a Turbosmart kompact BOV on my car yesterday and it was making a weird hissing noise on acceleration. My car has always made a flutter noise when going in between gears and bought this with hopes to get rid of that noise and replace it with the PSH noise. I have a CPE cold air intake...

    I’ve had my 2014 ST for a couple years now and when I bought it, it had a boomba racing BOV. I have enjoyed being somewhat obnoxious for a few years, but now I’m interested in cutting back on the blowoff noise. I’m considering going back to the OEM, or finding an aftermarket that simply much...

    Hey guys, I've had the Boomba 100% to atmosphere BOV for a couple years now, finally getting sick of it to the point of putting the stock recirculation valve back on. Dug around and found that box again only to find that the spring is missing. I've been combing parts diagrams for an hour now...

    Hello all, I have a 2018 focus ST with roughly 53k miles on it. Have some light modifications on it. K&N intake, muffler delete, and a boomba BOV. Nothing to crazy seeing as I still have factory warranty! (Tldr) white smoke out of bov side and exhaust, coolant disappearing, wet only on bov side...

    Used Turbosmart Kompact Dual BOV for sale. $110 with free US ground shipping. Bought about a year ago and used for approx 1500mi. Had some warranty work that needed to be done, so uninstalled and never reinstalled. To be honest, my ST is my daily driver with primarily city driving, and after...

    While maintaining throttle and between -3 and -1 vacuum, the BOV has started to consistently blow off 1 pound for a split second, every second so long as i'm between -3 and -1, roughly. It doesn't do this on higher vacuum, it also doesn't do this while under boost, to my knowledge (leaking). Is...

    Hey guys, I currently have my blow off valve tapped into the solenoid, I’m after a bit of flutter ( not getting any at the moment ), I’ve tried tightening my blow off valve to no avail. Will routing the blow off valve to the symposer delete help get more flutter ? I’m running a gfb dvx+. thanks !

    I have a Turbosmart Kompact Shortie Dual Port BOV and Stage 1 Cobb OTS tune on my '17 Focus ST. When I'm just trying to cruise around 60-75 mph and/or my boost pressure is sitting around -3 to 3 psi, my BOV pulsates. It's incredibly annoying. Has anyone else had this issue? If so, what did...

    I have searched all over this forum and I can't seem to find a straight answer. I just went FBO on my '16 ST3 and I have purchased the Turbosmart Dual Port Kompact BOV. The damn thing goes off even in negative boost. I know I can connect it to the boost port on my symposer delete, but what do I...

    Hi, all. I have a couple interesting issues here that I'm not sure how to resolve. I am running the Cobb Stage 2, 93 octane map on my 2018 Focus ST. 1) While holding the gas at an even position (cruising on the interstate at 65-70, 2800-3000 RPM), and when turbo PSI is at or around 1.00-2.00...

    So I have a 2015 FoST with the air box lid off. I really like the blow off sound it puts out with the stock recirculating valve. I was wondering if I’ll get close to that sound or if it’ll be a completely different sound or if it’ll be both I guess. Also I’m brand new to the community, I just...
