Decided to try the green spring that came with it that was being raved about and it responded the best while letting off the throttle. But it felt very sluggish when building boost during partial throttle and even came up 1 psi short on my wot pull were im normally at 23psi on my 20g i was only hitting a little over 22. I then switched back to the yellow spring and it was back to normal and responds just fine and boost onset was quicker and hit 23psi again. Just thought i would share my experience im sure it is not the same for different applications.

Is there any way using 100% recirc bpv, on a 2012 wrx to get the recirc sound audible without putting aftermarket sri, or a BOV on ? on my last turbo 2010 mazdaspeed 3, I had cobb sri, on and could really hear it...i kinda want that, but without messing with the intake, since they (forums state all need a tune for safe measure in our cars), and don't want to mess with certified warranty, factory warranty, plus dealer unlimited power train warranty.

In short, no. Putting even the forge BPV which is 100% recirc, or any aftermarket valve will be slightly louder than stock, but not worth buying for the difference it'll make. You need any intake at all and a BPV to really hear it.

I've been running the forge BPV for over a year on the factory intake and there is absolutely no sound from it. I have the "second" version, though, which is the quiet one. It's awesome and does it's job and looks really good in black! If you want noise, you will need to get another bypass valve or blow-off valve. The Forge model won't make any noise (with the factory intake).

I have an extra Green spring for $10 shipped if anyone is interested.

Brand new.

Reason why I went with the Green also was because when I boost in 5th on the hwy it would dump and have a little bit of surge. Now it recirculate smoothly and I noticed it doesn't dump as easily from 1st-2nd (which makes sense to me, why dump 2psi of boost while cruising slowly).

Anyone have any issues with these leaking at the seams? I did a pressure test in search of leaks while hunting down a fuel trim issue the other day and found 2 leaks on my forge bpv. One was were the flange meets the valve it self and is screwed in from the bottom no matter how tight it would leak at the seam. The other is were the outlet for the turbo inlet return screws into the valve. The seam for the flange has a oring inside that seems to be to short so i got a thicker oring to help it seat better. The return outlet has no oring on it from the factory so i also installed a oring there as well. I will install it today and report back if it still leaks or not.

Thanks for the write-up Ben. This is the second thing that I've purchased based on your reviews; haven't been steered wrong yet!

Question for all Forge BPV owners: mine seems to have a short delay in releasing pressure, when compared to the stock BPV. The stock one would make the sound right when I let off the gas or shift. The Forge seems the have a delay between my shifting/letting off throttle, and the BPV sound.

Anyone else notice this?

I am running the yellow spring with no shims @ ~20lbs; no flutter or compressor surge (thankfully).

Thanks!

I custom ordered the lightest green spring and it's been perfect, response is super fast between shifts and no flutter. I am @ 18 psi. I think the heavier spring the more delay, but I could be wrong. I'd wait for a few others to chime in.

I'm waiting for my forge bpv! I'll try the yellow spring without shims.*( 19-20 psi) .

I hope to have no problems with compressor surge without shims.

Blue spring with 2 shims is very agressive and responsive.

Trust me

Should mention im running 19 psi with no surge issues what so ever.

Mm really ? I thought to try the yellow spring with no shims. Now I'm confused with your comment. (19-20 psi ) .

The spring/shims have nothing to do with how much peak boost you can hold. Only how fast it responds. A little spring will vent sooner. I liked the (special order) green spring the best. The included yellow one works well too. No need to go stiffer than that.

Forge Bpv installed!!! Perfect fitment...Yellow spring without shims ... sounds a bit higher with the aem intake, the response is much faster and the car feels stronger.

I have no sound of compressor surge ( shshshshshshshhhh )

I will make a video !

The spring does not dictate how much boost it can hold. Yellow spring will hold more boost than your turbo can make.

Just checking. So 23 psi on a 16g xt should be fine then with the yellow spring.
