BPV vs BOV and how to install?

I've been curious as to what I'd need to install either the bpv or bov. But which ones better for the car and better for performance!? I am on my cell trying to search and can't find anything with the search so if there's a thread already then I'm sorry haha

from my understanding you really could call a BOV a "ricer mod" on our cars and wont benefit anything but sound.

If I had an SS/TC id run a HKS SSQV no questions, love the damn things and love the sound!! but I dont believe there is any other benefit.

again from what ive seen, you have to have one welded on a custom charge pipe. Definitely cant be done with stock piping. and you have to get a tune for it.


Although this is just from reading knowledge, I dont own a SS/TC so hopefully someone can fill in the gaps here.

BOV has no gains and only makes tunning a nightmare. As mentioned its a ricer mod. BPV and intake produces the same sound as a BOV and is just as loud. I ran a HKS and it was fun for like a week then got annoying quickly so i switched back to OEM BPV.

To run a BOV, first you need to buy an upper charge pipe with a BOV Flange. Find the BOV you want, and get it welded on. Then you need to install the upper charge pipe, and buy a block off for your stock BPV which is on the stock turbo. Then you need to buy a lower charge pipe with a MAF relocate...get tuned and you are g2g. It is a bit more in depth then that, but its the basics of buying a BOV

They are purely for sound on our cars, since the stock BPV vents the air fine.

this topics been beat to death.... a little searching goes a long way.

factory bpv is fine despite what people say. it can hold boost just fine. the ones in the efr work well too(have a different spring usually). going toa forge BPV isnt a bad thing either but its a maitence item and needs to be kept properly lubed

bov isnt a bad thing but i would only do it if you go to a big turbo setup. you need a maf relocate.... running it in conjunction with the factory bpv is a total waste aswell. you need to be tuned when u do a maf relocate. the only time i see this being worthwhile is when you go to a big turbo setup.

in all honesty get yourself an intake first and you will hear the bpv open. thaat might be enough.

But the important part is the BPV recirculates it where a BOV vents out of the system.

Read what Mike said here. It has a lot of wisdom. I highlighted the important part.

Meh, most will tell you you are an idiot for putting one on but I do love the sound. I want a HKS or a Turbosmart...still undecided.

I'd love to have one but I have other things I'd like to dump 800 bucks on for extra sounds.

Morning to you too......... read my post op. There's better things to blow money on then a bov. I'm not gunna call you stupid if you want one. Its your car you do what you want but for a stock turbo car its a waste IMHO.

I run the Tial Q Bov with no issues, you have to buy the new upper charge pipe and a bpv block off plate tune the car and re run some of the vac line and it runs great. A lot of people say you have to run the maf relocate but thats not true. Most say its a tuning nightmare but I dont what the hell they are talking about. I am fully bolted and running E47 and my car runs great, the reason I upgraded to tial bov is bc im going to upgrade to a bigger turbo on down the road. If you have any question or concerns feel free to message.

First off I put a cai on my car and made the Turbo a lot louder & you could hear the bpv really loud, however later on I put on a whole new larger intercooler with piping that had a flange and it camthwith a bv. The. Bov was much louder and had a more distinct whistling sound when it opened. IMO sounded a lot nicer, even if a lot of people consider it ricey. I did have issues with how the car ran, however I attribute those to other things that I found on down the line. The only major issue I ever had with it was that it was a cheap knock off of a greedy type rs bov and not well made so a couple the o ring around the piston would come off and wouldn't seal and leak boost so bad that the car would not run. So if yyu cire to go with a Nbov don't go cheap. I wouldn't mind a better Nov but right now I just have it turned all the way shut and arerunning the factory bpv. lease excuse miss spellings phones autocorrect messes me up

So if I plan to keep the turbo stock I should leave it as is? Its only for sound that I'd be interested and its not ricer or else doing a lot of things should be considered rice

the stock bpv with a SRI is just as good sound wise as a bov. I hear the bpv and turbo quite a bit with my K&N.

Yes, if you're looking for reliability, and consistency, just stick with the stock bpv. It's more than fine. Lots of other ways to spend all that money.

on stock tune I had my hks bov running with my forge bpv and no issues at all. I have a block off plate but cant figure out how to hook up the hoses so I get no surge. Run the bov with the factory bpv and it sounds great.

Get yourself a K&N, leave the stock bypass valve alone.

Only time I'd run a bov is if I did a turbo swap and the turbo didn't have a built in bpv
