This video seems like a good idea, but useless when almost all the examples arent even a 2015+ WRX, some arent even subarus! I would really expect better from MAP
I was thinking the same thing only 15+ Rex and rest are older and he says easy installed lol yeah ok, my blow off valve is under car ain't that easy on 15+wrx
@@maperformance yeah it should but the positions of the bov are in two different locations. there is so much in the way of the fa20dit bov since its all the way in the front on the right and the ej is by the intercooler. so the sound isnt gonna be exactly the same due to not really being able to hear it. why not use idk a 2015+ WRX with these bov when you make a video for 2015+ wrx. Not an STI. just a thought.
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.
For some reason I’ve never really liked the PSHHHHHH sounding ones as much as I’ve liked the flutter sounding ones. With that being said I’d go with the HKS one
would be nice if you tell people that most Subarus aren't designed to run a BOV and in fact you should be using a BPV. Can I also point out there one in the background is stock
THANK YOU!!! Someone who knows a little some thing. BOVs are never a good idea on a vehicle using a MAF. They cause all kinds of problems with fuel trim.
Kinda surprised they are showing EJ engines in all the shots and don't even mention the fact you absolutely need a custom tune to even run one on an FA engine..... it's kinda a pointless video. Missed opportunity to actually offer AP OTS tunes which are made for each specific BOV.
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.
The FA20 does use a bpv, however adjustable ones like the gfb which comes in 100% bypass or fully adjustable are also able to be used. Boomba may be the most popular, but most tuners dont recommend it.
I like how at 6:20 they exposed how the turbo smart blow off valve threaded piece will not go with the crank case pressure pipe infront of the intercooler
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.
I have a muffle delete with big tips and I have the Perrin bov I cant hear if for shit if I have my windows or up! But if you focus on the “psshhhh” you’ll hear it , not too loud but the throttle is more responsive! From a scale 1-10 I give it a 7.5!
Holy fuck, these are expensive just for a part that doesn't do anything other then make sound. Stick with the stock BOV/BPV. They work perfectly fine. I would be spending those money for stuff that can actually give a gain in performance then just blowing air through a whistle. You can get a good exhaust system with those money.
Noises are great, but I'm for what works best in my (recirculation/closed) FA20 system...sure, dual is OK, but I don't want to run too rich. I'm looking for a fast responding, tunable, serviceable/rebuildable recirculation (Bov) valve. I haven't seen many tunable/serviceable recirc valves for the fa20; let alone the kits to add different springs. Any suggestions?
having vented HKS SSQVs forever it only runs basically a little rich between shifts.. Never had any issues other than that with my AFRS when i check.. HKS has a recirc kit included so no worries if you want that and it works under low and high boost no springs required
My top is Tial and only Quality Tial. After trying all of what you have on the list I only use Tial. Check out my channel when you have a chance! Great comparison video 🤙🏼🤙🏼🤙🏼
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.
You’re gonna need a tune if you’re gonna put in a blow off valve. Also, if this is your only mod, you would get 0 hp gain from it. Probably even lose some power because air is vented instead of recirculated.
I would disagree - don't need to tune if you install a BOV. Won't run rich as the a/f ratio is only affected when the throttle is closed, no fuel being injected then anyway.
You do not NEED to but it might run better and more efficiently with a tune, but if you buy one made for your vehicle. More than likely the default settings will be runnable👍 and some come with adjustable dials and some are preset how they are made to be as well
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.
Any mods you should run a tune. Even a simple exhaust I would run a tune. The access port would do just fine. No you don't need to change the maf sensor. It's plug and play
@@krisgrafili6780 Anything post MAF(metered air that your ECU is expecting for combustion) that will exit at some point before entering your engine needs to be accounted for. aftermarket Downpipes flow more exhaust gases than stock, Intakes draw more air than what is expected by the ECU on the stock tune. 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.
I just bought a 16 wrx premium, new to all of this. What would be the best bov for a daily driver that doesn’t want to worry about causing and long term problems to the engine. But, wants a good sound ( I want to hear the turbo ) thanks guys!
I own the 2015 wrx sti with the 2019 type uk ej257 short motor, i installed an HKS SSQV4 bov and it caused the car to run rich popping on throttle back off and all that wonderful stuff. 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. :)
I'm between the HKS and the TurboSmart. I like the high pitch pshhh of HKS, and I like the versatility and sound of the turbosmart too. which one should I get????
I highly recommend looking into the Forge bpv/bov. Extremely unique sound, flutters at low boost & sounds like a cross between the HKS & the GFB when you giver the beans
Went with perrin got it from import image racing for $165 it was $35 cheaper than ma performance

All of these are for STI’s not WRX’s. Clearly those are EJ’s and not our FA’s. The title needs to be changed to STI. IMO
Can you please advise if it is safe to upgrade for for BOV on my stock subaru wrx 2015

ivebeen fax yo
Flutter is for butterflies
The proper flutter is from not having a bov
Flutter isn't from the valve...
I’ve got a blue turbosmart adjustable bov set to 50/50 on my 15 STI , flutters and goes pshhh at the same time 🤩
Is it nice?
,

Because you have an STI not a wrx..
I’m confused! I see a Mazda in one of the videos while the rest are STI’s. Are all these cars called WRX nowadays? 🤔 @maperformance
Lmao thank god I wasnt the only one.
Absolutely thanks for pointing that out! Good thing the sound should be pretty much the same on most platforms.
Lmfao I was geeking when I saw the Mazda
Blow off valve is definitely my favorite sound a car can make
Suuuuututuutu better
@@Ye-yz7cx I like the turbo flutter better but I think that lowers the mileage of your turbo so I’d go with a bov

Doesn’t the FA20 engine need a BPV to keep reliability
Kidscope I was wondering the exact same thing! I’m about to order one and now I’m confused! Either way I’m going to play it safe and go with a bpv
Same?? Here.
Yes, a fully recirculating bypass valve is needed. This video was made by someone who doesnt know what they’re talking about.
i use the gfb bov it's perfectly fine as you can set to 90/10 recirc so still doing the bypass and get the flutter sound
THANK YOU!!! Someone who knows a little some thing. BOVs are never a good idea on a vehicle using a MAF. They cause all kinds of problems with fuel trim.
Very misleading video based on title and thumbnail. Especially all the in accurate examples given.
The video was about price and how they sound. That isn't going to change on a different car.
Those are STI vids 🤔, they dont have same bov/bpv as the FA
I went with boomba and love it!
came to check the sounds but ill be sticking with Bypass Valves to keep my STI happy.
Kinda surprised they are showing EJ engines in all the shots and don't even mention the fact you absolutely need a custom tune to even run one on an FA engine..... it's kinda a pointless video. Missed opportunity to actually offer AP OTS tunes which are made for each specific BOV.
Should this mod be done on a stock engine?
How bout us still driving older subarus?
i know bro, i dont like the look of these new subies and im starting a GC8 project. everyone be about these 15+
VA sucks
Bugeye here and I want to know what one gives the best sound?
I have the boomba blow off valve and it honestly sounds better than all of these. I would go with HKS though
Lopez Susan Gonzalez Gary Harris Michael
Do you need to have a tune on your car or can this be install with any tune.
Ii this a joke. I cant even hear the hks in the clips where the cars dont even breach 4k rpm like what a waste of everyones time.

It's all wrong anyways unless you have an sti...thought this vid was for WRX
Hall Lisa Taylor Scott Perez Carol
One of the dumbest things you can put on your WRX
So you say WRX and almost all examples are STIs...WRX BOVs are underneath not on top.. so wrx bov make a different noise than sti...so pointless

I want to know what makes the rally cars do that chirping noise its not stustu more like chirp chirp. Is that also from a blowoff valve ?
Hi, how do you get the air flutter sound on the ssqv4? Is that with the recirculating kit? Cheers
Tbh that’s compressor surge and you absolutely do not want that
@@bakersavage229 but it just sounds SOOO good
Can you you have like half flutter half pssssssh sound ?
So question is… would I have to tune the car in order to order any of these ?
very smooth talking Charlie Mayne lmao fyi we need one of these for the q50/q60 community
Will any of these work on a CVT?
Wondering the exact same thing. Any updates ?

1:08 that single stuu blow off sound. The hks sounds a little different between drivers. Can you adjust it to make it sound different?
Can't even hear the cobb one
Funny how many people think compressor surge is desirable
Is a tune or anything else necessary with these?
I still like the HKS SSQV more.
How does it sound on an automatic transmission?
i just ordered the GFB but very concerned, i see it’s safe but unsafe to run on a untuned wrx, can people please clarify this for me
You should have no problems running it on a stock WRX!
do they have to be tuned to put a bov in?

What setting would be a higher pitch noise rather then a whoosh noise
Are these legal in CA?
For STI do you want to recirculation valve not a blow off valve
Alright you guys
But you shouldn't put one of these cool blow off valves on a stock wrx sti right??
can you make performance videos of a nissan r34 or evo3
I want all of them.
Greddy ❤️
No boomba?
Also a good option we have available on our site!
Is the HKS BOV flutter louder with the MAperformance STi Intake?
The BOV volume won't change with a different intake. Will be slightly louder/more aggressive sounding with more boost pressure though.
Hks bov is my favorite
Do you have to tighten the nut on the top for the vacuum line or is it supposed to still turn once installed?
I highly recommend looking into the Forge bpv/bov. Extremely unique sound, flutters at low boost & sounds like a cross between the HKS & the GFB when you giver the beans
Do you have one? I can only find 2 vids and I can’t really hear them that well
and do you recommend the atmospheric or recirculating?

Quite possibly! Stay tuned, this could be a possibility sooner than you think 😉
