Stock BOV Plumback removal

[DezertEagle]

Jus wandering what would happen if i took the plumback piping running from the stock BOV....

[RBVS]

I did once, got left off by axcident, not much happened , blow off was much louder, big whoosh. be carfull if you do because the return runs back in front of the turbo with nothing to stop crap getting in and hitting turbo wheel, say good bye if that happens. :Bang:

[DezertEagle]

ahh so if i block the return pipe and leave the factory valve mouth open ... it will woosh?! *excitement*

[NRB]

It'll be illegal, but yes, it'll "whoosh".

hmmm is there alot of vacuum coming from this pipe/?? Coz if the turbo is sucking then i guess a vacuum would be created!! Im keen to try it

[DezertEagle]

I"M EXCITED (Big Kev)

[sweetr33]

what would happen if u put a piece of woopy cushion over the end of the bov snout?? Hehehe imagin the noise hehe

hey guys i got a r32 and **** me u can hear the std bov a mile a way! I have a hks air filter and all the pressure is blown out throw that as there is nowhere else for it to go! sounds good!@not sure if the previous owner took the plumback bit off?

[sweetr33]

anyone know wat happens with that pipe that would normally go to the snout if u block it off with something???

[R33Steve]

The pipe i think your talking about is the one about an inch in diameter going down towards the turbo? Thats the recirculation pipe it goes back into the pipe from your air filter and is plumbed in just before the turbo. If you take this off youll have to modify your pipe from air filter to turbo, either getting stainless piping or patching the stock one.

Most cars stall when they come back down to idle when if the recirculating part is blocked off.

It will make a good noise but because the extra air is not being put back into the intake the car will run rich during gear changes and when backing off from accelerating!

.... but does sound ok

[xRHETTx]

Just get a pod filter and leave the plumb-back in place, the sound will be almost as loud.

Hehe, i think a kazoo or something would sound pretty funny too.

ok i tried this the other day and yeah the car runs heaps rich. I loved the sound but....the car wouldnt idle properly and stalled most times i came to a stop. HOWEVER if u disconnect the vacuum line going from the inlet manifold to ur BOV and block it off then..... insted of pshhhhht its "FLUTTER". Sounds amazing and the car runs a little richer but not really noticeable

What, the whoopie cushion idea? Or the kazoo idea?

[RedDrifter]

sweetr33: That flutter sound is the air going back through the turbo. Sounds sweet hey.

Not sure how good this is for the turbo though.

[nitemare5]

its fine for the turbo if u dont run insane boost levels

Check the net and you'll see its been done before, theres some movies around, I think it was some sort of Mazda, tried various things, eg baloons, party streamers etc, sounded quite funny. No link sorry, shouldn't be too hard to find...

Btw, my stock R32 GTSt bov is like twice as loud as the my GTS25t one, same filter too, dunno why that is...
