Bov?
right. If you have a recirculating setup, like the stock bpv has, the turbo can spool faster. Plus you'll run rich between shifts. The only way to run a bov correctly is to either run it in recirc mode (loses much of the sound, and basically acts as an external bpv) or do a maf relocation to the cold side charge piping and get a tune.
He wants this for sound so recirculating it would be completely pointless
This is what I did to let people know I had a turbo

But for reals get a maf relocation and a this is what it'll sound like

I've been on the Forge BPV for a few months now. No performance change, but it can't tear. You need to lube it with synthetic grease, like Mobil 1. Do not use cheap grease! It will stick if the grease goes dry.
Use the lighter spring. The heavier one is unnecessary, and will cause some minor surge.
I have no surge. I also have the Hahn intake.

What particilar Mobile 1 grease is it (weight type etc)
And Does it come with a lighter spring?

DEJON | Powerhouse they have everything you need but you will have to relocate your mas.......it cost me about 600.00 without the bov so about 800 total for everything

I am basically thinking about putting one of these on my 09 SS. I just want to know what the negative side to doing it will be. Obviously I will get tuned for it and not just put it on a stock car, but I want to make sure that there won't be any negative side effects.
I am doing this 100% for the sound, I like it and I think it sounds awesome. If you are just gonna post in here and be a troll, please spare the **** and go somewhere else to get your rocks off. For the people that can provide me with real information, please leave whatever info you can for me. Thanks.

Other than the bov, if you haven't thought of this stuff already, budget for a bpv block off plate, and a charge pipe to mount the bov in. You don't have to relocate the maf, I didn't, just diable the P0101 maf code on your tune, if you don't it will throw you into limp mode from time to time. As you can tell I have all treadstone stuff. Its all really well setup and looks nice. if you want to check it out just click my sig and you can go to their page. If you have any specific question let me know.

The debate rages onward...
for stock turbo, forge bpv is the way to go. If youve been in the game long enough, you will end up with a forge bpv on the stock turbo. It takes some longer than others but hey, we cant all cross the finish line first. Eventually you get tired of the sound of a bov, or it starts to eff up and youll realize you shouldve got the forge bpv from the start.
For a B.M.F.T youll need a bov. Just too much coming at it to recirc. Course if your able to do a bmft setup, i dont think youll be concerned at all about a pleasurable audible experience. Thats actually where all these sound amplifying bov's come from, the attempt to reproduce the sound of a bmft setup.

Actually, on Borg latest and greatest aftermarket uber turbos, they use the exact same BPV setup that we use. I'm sure the internal orifices are larger to allow more air to pass. If it's good enough for a monster 1000 hp turbo, someone tell me why you're going external BOV.

EFR turbo compressor housings incorporate an integrated BOV. Yes, you read that right - the BOV is a recirculating style *built-in* to the Compressor Housing. The major performance advantage in this design is that it redirects the high-pressure compressed air from the outlet of the compressor wheel -> right at the low-pressure inlet of the turbo. This helps to keep the turbo spooled between shifts and offers cost savings/convenience while keeping MAF-based engine mgt happy. With this in place, there is no need for a BOV or flange on the charge piping. The only downside of this feature is the fact that it makes the compressor housing about 1" (~25mm) longer in axial length. For the hardcore racers who want to use an external traditional BOV, and for applications that can not fit or do not want to use the internal valve, we offer a disabling cover plate. This cover plate installs in place of the plastic cover and uses the original diaphragm to seal the port.

Thats true grishbok. My original intention is to turbo swap next year. The bpv would be going byebye anyways.
EDIT: Yea but wang alot of aftermarket turbos don't come with the bpv in place already. I'm not trying to defend the bov or the bpv. I just got mine for sound at this point. But if I turbo swap next year it will have a real application becasue most of the turbos I can get don't have a bpv. I agreed stock turbo = bpv > BOV but some plans call for different routes.
