running 2 bov's

[meet07]

I always see highly modded supras running like 2 greddy type-s bov's or 2 hks ssqv.... I know there doing it b/c on of the bov leaks/fails at like 500 hp or so.. but would it hurt to put 2 on if your making like 300-450whp??

and would it sound louder since 2 are blowing off instead of one?

[Sil240]

Just buy 1 good BOV. I think its because. It looks. Cool.I guess it would sound louder too.But why spend $ twice? ??

IMO only people who are functionally entitled to are drag cars.

[robbie2883]

just FYI, the law of sound is if you double up on something you increase the sound by 3 decibels

The Supra in the video is running twin hks's with single turbo. And the only Supra that I have ever went for a ride in was running the same setup. And his bov's where super loud at partial throttle...Ive always heard that both the hks and greddy type-s bov's run out of steam around 500whp or so...2 hks's seemed like an alternative instead of getting one bigger bov(hint the sound)

guess its preference?

im only running one BOV in my 9 second daily driven evo, I run upwards of 40 pounds of boost on killmode and my one bov does fine.

That's why they make the Greddy type r and other large diameter bovs. All it is, is a pressure release valve.

Look around before spending tons of $$$.

2 bovs causes a lack of space and more space in your wallet.

[SullivanRacing06]

oh there lacking something down low and need to make it up by running two inferior bov compared to a larger single...thats meant for thoes hp goals

[Sil240]

Also you've gotta set both BOV's to go off at the same exact time.

Buy one of these:

47mm valve, 50mm outletWith the stiffer spring 11501661 its good over 375hp

11501660 good for 280 - 450hp

Or one of thesehttp://www.tialsport.com/prod_bv.htm

Alpha Q is 50mm and can be recirc'dkinda ugly IMO, but it'll do the job.

The BV 50mm will hold up to 80psi.I'm sure you wont have a problem with this..

Not if there twin ebay greddy type-s bov's

they use 2 because they move more air than 1 can effectively release.

2 will not be louder (i dont care if it actually is, thats gay and you shouldnt do it)

[LSDrift]

No offense to anyone but if there was a facebook like this button on the forum I would like the last part of that comment Joe hahaha.

[meet07]

Im suprised to not get the torch..I use to have a greddy type-r on my turbo b16...It caused nothing but compressor surge since I was only running 10psi....

im looking into the synapse...or i may keep mine..

[Sil240]

Read the site.Its meant for Big boost.10 psi is not big.

But from your posts your looking to hunt down Ferrari's and Veyrons etc...

Pull that off your B16 and slap it on your RB.Go buy a regular BOV for the honda.

The Synapse is good, but I don't think its meant for really big boost. Being that its a Pull type it wont open up on you.But... it might not release enough air, fast enough.

Check the sizing of the valve and the orifice.

Looks like 50mm is the large size.

I parted out and sold the integra to fund this money pit!! I have this sitting at home in a box. But im not sure if I wanna use it??



Copy cat HKS Racing Type-II

[boosted98gst]

No offense but do you really care what a BOV sounds like? Most people that go fast can give two craps about what, bov is loudest or sounds coolest. Id rather just have one that does it job!

No offense taken...but yeah if I have more than one option of BOV's then yes I want it to sound good...What if the best performed bov sounds like a duck call, or a balloon poping....would you still get it???

I mean thats why we all like turbo right?? The performance and sound!

[Sil240]

I love that HKS BOV!!!I usually only see the SSQV.I think Carl runs that one.

What size is that outlet?Can you get a larger outlet?What size is the inlet to it?

If I were you, since you already have this BOV hanging around.Keep your $$ in your pocket and run that.If you have a problem with it then sell it and go big dog BOV.

Everybody cares what their BOV sounds like.But.... Riceboys obsess over it and base their purchase soley on sound. Not function.

[meet07]

Ive grown out of rice boy status years ago. Im currently running a RFL which I thiink is also good for like 30psi or so...

since we are on the subject of bov's, Isnt it better to have a pull style(stays closed at idle) with a maf setup??

[Sil240]

Yeah from what I've been told a pull type will stay closed at idle. I should of kept my SSQV.

If not you'll have to be ghetto like me!!!

I have the hks racing type 2. Works fine or 400 whp.

[meet07]

I really have my eye on the synapse!!

We all have much different opinions, persoanlly id never support knock off part companys but thats just me. I must be different from others because the sound of a bov is not big on my list. Personally I cant hear much when im turning 10000 rpm's and my turbo is sucking in the car next to me.

lol what?

youve grown out of your ricer status yet just asked if 2 would be louder? and you are also using the RFL aka the loudest BOV in history.

[meet07]

Joe your a trip!! I meant like big spoilers,huge body kits, slammed and tucking rims, etc.....

I love this bov doe..

[Joe]

having a super loud BOV is on the same level as a stupid wing dude.

a single high quality bov thats built for your boost level is your best option.

if you cant figure this out go back to your integra. two bovs are over kill, if you see a 300zx with twin bypass valves its for a purpose, ie each turbo has its own i/c like the new skyline, they do it for a reason other then to make noise, they do it for functionality
