Best Sounding Bov

[conan7772]

Right now I have an Apexi slide adjustable BOV to atmo with an RB25/30 with a GT3076R.

It sounded better before with the old high flow on medium orifice.

There was a relatively loud clean flutter that would growl deep and spook dogs.

Now with the 3076 it is set on large orifice and doesn't flutter as nice and is also really F%$#@%^loud on high boost.

When it releases the pssshhht, it's like someone is smashing a bottle right next to your head.

Now with the cops increasingly picking on us I wanna plumb back.

I don't think I can plumb back this BOV.

I've heard a few S15's getting around with a really cool high pitch flutter.

Not too loud, like a whistle lowering in pitch as it flutters.

Can anyone tell me which BOV's do this and can be plumbed.

I only track it once a year so ragged edge performance isn't a total requirement.

cheers.

Is running your BOV from when the car was stock an option?

I still have my stock BOV and its plumbed back, but you can still hear it pretty easily through intake and pod filter etc.

Bump guys and girls.

This is important.

10 years from now there might not be any Skylines left on the road !!

I think hks ones sound like what you described go type on yputube and listen to them.

[KiwiRS4T]

Not clear what you want to acheive.

You want a noisy bov

You want it plumbed in because of the cops?

The only police objection is the noise - a bov vents only air so its not an emissions issue.

What is important? Personally I like my bov to be completely silent.

It is an emission issue, air escaping thats been metered = more fuel which means rich which means carbon. Well in NSW anyway its an actual fine not just defect. Not sure about vic

[dirtyRS4]

most bov have a soft or hard setting allowing for the sound to be adjusted like on the collar with the apexi, make sure you get a plumback.

i have to admit the apexi dual chamber would be one of the louder ones on the market. hks, sard or trust all have a unique sound.

Anyone that puts a BOV on for sound is just a plain f**king dickhead.

Dude,

I'm looking for a plumb back one that's quieter than what I have.

Whilst I'm at it I don't want to drive around in a farting horse.

Engine and exhaust notes are very important to some...

you mean like a GTR? ..........

*hinnt hint*

[kitto]

Bovs are totally gay. And so are people that fit them.

If you want a bov, use the stock recirculation valve that is still plumbed back.

[75coupe]

where do the GTR bovs sit in the engine bay?

I gather they just use a rubber hose to recirculate back, does it run under the engine or over or what?

[Godzilla34]

Bov!

[gotRICE?]

GTR Bov's are in the drivers side bumper, they have a plastic tube that runs along the radiator support or somewhere around there.

Mafia.. stop being such an asshole all the time.

Drivers side.

There is a plastic recirc pipe that goes under the radiator back to the intake side.

GTR BOV's are good for any application.

If you want less BOV noise, run an airbox.

Some people like BOVs, some dont. Some people like bling rims, others dont.

Just because you have a distaste towards BOVs, doesnt make this guy a dickhead.

OP, try a "dual port" design BOV. I have a Turbosmart dual port, one port is plumbed back, the other vents. I got a restrictor machined into the vented port to lessen the sound. You still get a nice sound (not overly loud, or stupid sounding), and because it recirculates to a degree, the "richness" on gear changes etc, is somewhat lessened. And, if you still have a AFM between filter and turbo, the flutter is there, but sounds low and sexy.

Not obnoxious like those "hectik bro's" in their "fully sick" VL's.

But, as i said, each to their own. Food for thought

Ty.

[Adriano]

But just as illegal as an atmospheric one. IMO aftermarket bov's are like christmas, 99% marketing to seperate people from money

[Dajae]

Just as illegal, yes. I agree with that definately.. I was talking in regards to the effect it has on tune/emission.

Agreed, a large portion of people buy because its marketed well. The other portion, know it does have *some* performance benefit.. Depending on the setup, of course.

Personally i have one because it decreases "flutter" coming from a system with no BOV. ie; that horrible "zuuuuu tututu" sound you get with most VL turbos. And because of the modification, it doesnt sound stupid either.

The flutter i talk about that i have, is actually the sound of the BOV fluctuating in response to the build-up of excess pressure in the intake tract.

Personally i dont like extremely loud "pssst" sounds..

Makes driving annoying.

[sinistaGTR]

your mums a bov....how hasnt this been wastelanded or just locked yet.

if you want to hear a bov noises that suit you, listen to friggen youtube and choose from there.

there are some seriously stupid topics on here at times
