Help needed in making BOV plumback -> Atmo venting

[Wink]

Currently I have a GReddy Type-S BOV plumbacked.

As you'd know for plumback, the pipe doing the 'plumbing back' is connected to the air intake pipe. It's connected to the intake via a solid rubber hose clamped on. One end is clamped to the BOV 'exit', and the other is connected to a metal pipe leading to the air intake.

Now I want to try to make the BOV atmo venting. I have to remove this rubber hose and leave it open on the BOV end (so air exiting the BOV gets vented out to the atmosphere/open air).

What concerns me is the other end of the rubber hose ie the metal pipe leading to the air intake.

Can I just leave it open ended or do I have to seal this end of the pipe?

If I have to seal it, what is the best way to do it?

You have to seal it, otherwise you'll lose air the AFM has already 'counted'.

Is there enough of that pipe to use a rubber stopper ? My catch can vent is put back into the intake pipe but it was done so I could take it out and vent it to atmosphere should I need to. They gave me a rubber plug, which is essentially the same sort of thing as you'd find on a cheap table leg. This would stay on with a hose clamp.

Not sure if that would work for you cos I can't picture how your bov looks like but it might give you an idea

I guess a rubber stopper would work but it sounds abit ghetto and the rubber stopper would have to be pretty large in diameter (about 3-4cm wide). Also with a solution like that I'm afraid of a situation where it may jolt loose and fall off.

mines got a rubber bung pushed into it

easy job

has anyone done this with the Standard BOV? I wonder what it will sound like.

I used a coke bottle lid in the hose end with a clamp around it.There's no way in hell it would get sucked in.
