Very insightful. I always wonder if my factory bov is still working properly. There are no apparent problems with it but I feel like a brand new valve with better audible feedback would be more reassuring.

With my first 07 wrx back in 08 as a kid with zero knowledge I added a bov in the beginning, it was alright, then started leaking and the car would stall at low rpm starts. I took it off and went stock BPV for life. My current 06 is running an 18g xtr 10cm and a lot of other mods with the stock bpv perfectly fine. The bpv/bov never seemed like a necessary mod to me and I have almost always run a FMIC too.

Hopefully I didn't overlook my question, but is there any "performance" advantages to running recirc? When would you want one versus the other?

Recently got a protune on speed density styling tuning for my 13 WRX with 19psi target. My tuner actually recommend an aftermarket valve. I went with GFB because it's hybrid and it was a decent price. I am currently running at 50/50. Spent awhile dialing it in and still get just a very little bit of flutter in low rpm occasionally when I lift. Seems to be working fine. Can't say I notice any performance advantage, just noise.

Great post! I was interested in purchasing an HKS SSQ but I'll probably be rethinking that now.

Anybody have an answer to this, I have a greddy vta blow off valve and I'm having a hell of a time tuning it.... For some reason it tends to stay open after I change gears and leak boost or it's too tight and I get turbo back surge so if there's any tips to find the happy middle ground that would be much appreciated and yes I've tried adjusting the tension on the spring and lighter spring and it seems to not find the sweet spot yet

Go speed density and you won't have to worry about it.

2008 wrx took it to TIC for inspection guy named Eric there told me my BOV was decent but he personally doesn't like them and also notices they make the car produce less power a lot of the time. He closed my BOV it was a 50/50 Go Fast Bits and after he closed it off I realized the car did feel stronger threw the gears and ran a little better. With the right set up and power I think it would be a great thing

New to the thread, found this very interesting. Seemed to de-bunk most of the myths associated with BOV. Sounds like there needs to be a device invented to make sure the BOV are not leaking and installed correctly. After all the bad I have read about them I might consider the Cobb 50/50, just for the added noise. After hearing a buddies, as dumb as it is I have always wanted one.

A pressure test is the way to test if the bov is leaking. You can make a tester cheap or buy one from frozen boost.

Pretty much the most common thing I saw threads about when I started looking about in this forum. BOV threads and issues everywhere.

This was a solid write up, you did an excellent job of answering my questions, and making me realize that with the setup I have, its far safer to stay stock.

So intakes are good ? I'm confused now,I read on unibom that they are somewhat bad,new to this !
