Just want to share a little experience with the community. Have a stage 1 MAPerformance with a few extra mods. Bought the TurboXS Hybrid 50/50. Installed it as shipped and couldn't be happier. Love it. My car is currently in the shop getting full Turbo back, TGV, EGR, TMIC and full stage 2 pro tune. Was called today and told the BPV is leaking and is a common problem during this upgrade. Stock BPV is the way to go. If I wanted that sound (because we know it does nothing for performance) then the Cobb BPV was the way to go. I was also told Boomba was garbage.

That is crazy I just spoke with Tony about this and will most likely be ordering one tomorrow from them

I’ve got a blue turbosmart adjustable bov set to 50/50 on my 15 STI , flutters and goes pshhh at the same time 🤩

The shop that tuned my car to make 350whp on e85 with the stock recirc, was against gfb bovs or recircs. They did not like it. I had a buddy that bought a 2008 STI with an IAG stage 1 short block that failed withing 10k miles. It also was running a GFB BOV.... Now that might not be the reason for his failure BUT even the shop was surprised that the IAG motor failed so quickly.

Turbosmart 👍👍👍

Another great video 👌

If you're mostly doing it for sound, why not just get an intake and at least get some performance out of it? Plus the turbo system uses a BPV that recirculates air back through the intake from the intercooler to keep the car from running too rich when you let off the throttle. An intake (I run the mishimoto race intake on my 16 STI with no air box since temps don't get that hot where I am) plus an accessport with the Cobb stage 1+ tune (which I run with no problems since the SF intake and mishimoto intake are nearly identical) is cheaper and less time consuming than paying a shop to get you a pro tune, which you really don't need unless you're planning on things for real power like E85, bigger turbo, etc. The intake sound is louder and sounds better IMO, just my 2 cents.

will the sqv4 dit on a stock 2017 wrx

For STI do you want to recirculation valve not a blow off valve

Hi subie lovers. I’m a newbie with subie, and all this stuff is very interesting. Does a BOV require any mods for the MAF sensor? Does it require a tune from say an Access port? I’ve had conflicting reports and I’m not totally sold on getting one. This is also because I’m not a turbo expert etc. thanks for your videos, I find them very pleasing to my ears.

If the ECU is trying to use the same amount of fuel for a now increased amount of air entering the engine, this causes you to run lean(too much air) rather than rich(too much fuel, not enough air).This will create knock events and eventually grenade your motor.

Im pretty sure the fa20 dit motor uses a bypass valve not a blowoff valve. You can use a boomba bpv without a tune but to run a blow of valve that vents to atmosphere would require a pro tune. Imho I dont think it's worth running ANY BOV. I done see it adding much power if any. More likely to LOSE power. The best bpv is boomba hands down.

Got recommended by the technician who fitted my new motor to map in any changes like bov valves from recircs' as it changes air to fuel ratios. Also if removing stock air box for k&n or similar cone type filter. something to do with the way the boxer engine injects its fuel in the inlet manifold and not direct injection. fa20 motor in 2021 motor apparently doesn't have this issue. this is just my experience and what i have been told by Subaru, could be different for you or your region. hope this sheds some light on your question. :)
