Without getting into detail, (as I'm not and expert) once the throttle is snaps shut on a gear change the excess air needs somewhere to go. The theory being that venting it through a big bov gets rid of more then circulating it back into the intake. But I suppose if they made big enough plumb backs to move enough air (which they don't) I assume it would be the same effect.

Hmmm. I just blocked the BOV and it's a fair bit quieter than having a 10mm outlet. I am thinking that I will put it back to venting to atmo. The concern I have however is that when vented the BOV is releasing air when the engine is idle, I wonder if the BOV is faulty? And if this is the case perhaps it could be letting unfiltered air in too?

I dunno I tried running with it blocked but it just fluttered way way too much imo.

The only way I could stop it fluttering on every gear change was by very slowly taking my foot off the go pedal did my head in.

Maybe on an auto its betta?

Oh yeah heaps better, none at all during gear changes only when you snap the throttle shut.
