BOV recommendation

[Limbo]

Hi guys just need a recommendation for a cheap BOV.

I want something that is quiet for a plumb back.
My turbosmart is abit loud for me, has a nice hiss but i want a stealth one.

Anyone with one who wants to swap?:D

[Riced_Civic]

get a trial stealth 1

[G3RA1D]

are you selling ur one for cheap? :)

[Aza]

stock evo bov.

[Limbo]

are you selling ur one for cheap? :)

yeah well once i get a replacement

[DLO01]

A plumb back is a plumb back. If your getting noise now, do you think you'll get in much quieter with another one?

[Limbo]

yeah been told that there are quieter BOVs out there.

[JasonGilholme]

i always thought that plumb back was plumb back?

Unless the noise is the pressurised air going back through the air filter instead of back through the turbo?

[Limbo]

hmm i dunno never thought about that.
The plumb back is straight to the intake arm inbetween the turbo and the filter

[Limbo]

Ok been searching around and found out that i have supersonic one

I got the plumb back for the supersonic one. I need to get the sleeper one.
The only thing is that i got the plumb back it came with another spring, which i installed.

Should i go softer to reduce noise? as i have it on hard atm

[DLO01]

Unless the noise is the pressurised air going back through the air filter instead of back through the turbo?

Thats exactly what it is. Thats what I have been trying to tell you Limbo as in the other thread. Thats the only way the noise can come out.

[Limbo]

does that mean i have to plumb it back and point it towards the turbo instead of just a straight 90 degree into the intake pipe?

Also my filter is sealed

[TODA AU]

I agree with Aza, use an OEM Mitso valve

[Centurius]

does that mean i have to plumb it back and point it towards the turbo instead of just a straight 90 degree into the intake pipe?

Also my filter is sealed
would probably be best to point it towards the turbo, but whether it's worth the effort is up to you..

and i'd hope your air filter isn't too sealed, wouldn't get much air in there otherwise :S

[JetSir]

go a hks ssqv = ]

[Limbo]

i'd like a plumb back so i can get it engineered.

Looked into the plumbback of my car, i think it is leaking thru the filter.

Guess it keeps the filter clean

[fatboyz39]

go a hks ssqv = ]

:thumbsup: We had this on our B16a turbo. Very nice sound.

[Limbo]

Kev have you got a spare by chance?

[STOCK]

meh... no go bro

[grumpy rooster]

OE evo/bosch item

If you want it engineered this is your best option.

[Limbo]

put the original spring instead of the turbosmart plumb back one and seems to be better, it quieter for some reason, dunno why

[fat_85_civic]

where can you get mitsubishi ones from? and about how uch will it cost?
Are thay the same as the black plastic bosch ones on volvos and stuff?

[Weq]

Look on the EVO forums. www.evooz.net. they sell evo 7+ bypass valves which metal and dont leak like other plastic valves. Personally i wouldnt ever runa plasitic bypass valve. They all leak.

Oh, and dont think a bypass valve will get u off a defect - on the lancer forums there are guys with stock bypass valves and shiney yellow defect notices. Its all about the shape. Pigs dont know the difference between a bypass or a blowoff. They dont know why its defect, they dont know how it operates. All they know is that its a defect cause of its the shape.

You best best, get any valve you want and stick it in the inner-gaurd. If a pig cant see it, he cant defect it!!

Everyone FORGET all these last BOVs listed... This is the K I N G BOV!

GFB Deceptor Pro BOV

Either plub-back or VENT to atmosphere OR turn off completely for Dose.... ALL by incar Electronic control. Basically its a small motor solenoid built into the bov will changes its state.

Similar to a TEIN edfc ...

has anyone ever tried this?

[Aza]

i will have my stock oem bov up for grabs soon...

replacing it with an evo 8 mr bov

[misteR_bilzz]

has anyone ever tried this?

There was an ignition DVD review on it, works very well...

took the guy 15mins to fit, adjustable from in car with the 3 settings.

[Sexc86]

Yes yes.... only downfall is price... I will Deffinately be running one on my next setup...

As well as Xforce VAREX... electronically in car controlled ( change the loudness of the muffler)

[dynosaur]

Blitz super sonic BOV

[Blitzen]

HKS sqq, heard one before - it's kinda like compressor surge sound, but no harm to ur turbo

but isn't bov's illegal? i've read from FIA motorsport regulations because exhaust is not filtered before they enter the atmosphere...

[DLO01]

Bov's are on the intake side. Your talking about a Wastegate.

[kraiye]

why would you want to filter AIR before releasing it back into the... AIR?
:p

thats a way heavy muffler for a cannon

but ur cars got the power to pull it :D

:p

I figured he was talking about a WG to atmosphere and therefore NOT going through the Cat. But yeh, no need to filter the bov to atmosphere, thats not gona do much. But legally it needs to be plumped back to your intake.

[kazam]

http://www.ozhonda.com/forum/showthread.php?t=54955

for that kit,
wat would be the loudest BOV to get? i wanted compressor surge but i cant have it coz of xternal gate plumbed back in2 the system blablabla pretty devo, so i may aswell get a loud BOV since i cant get CS...

[DLO01]

What are you talking about boy.:p Plumbing the WG back or not, will not affect surge.

If you want compressor surge, don't put a Bov on at all. Flutter all the way!!!

[dc2dc2dc2]

no bov
flutter ftmfw~

[kazam]

YEH i no how 2 achieve flutter, but coz its plumbed back i heard i cant get compressor surge, according 2 the person selling it neway....

[Killa From Manila]

as said above, wastegate has nothing to do with flutter. the guy may be talking about screamer pipe perhaps? the loud wastegate scream wen its vented straight to atmo

[RCS 20L]

Go with the MR valve. Nice and quiet. This oem unit can handle 20+ psi. You can find one here>>> http://www.meek.com.au/index.php?v=Product&id=160&pcid=29

[Aza]

the stock bovs can handle up to 20 psi.

the mr can handle up to around 25 psi.

massive price difference though....

im pretty sure limbo isnt running over 20 psi in his civic

[Limbo]

i get flutter at low rpm.
Yeah i'm only running 10PSI.
From what i heard of the Turbosmart Supersonics are made for high boost apps, can't rem how much anyway

[Limbo]

alrightly got a bosch BOV on the way. We'll see how we go now

[nigs]

Bosch, are they the plastic units?
If so, used one on the 4G93. Awesome stuff. Vents a dick ton of air for it's size. Springs are pretty soft in these things though....

[tiksie]

None.
