Gfb Stealth Bov Set To No Noise But Still Have Noise

[kaino]

Just bought my first turbo car an r33 dont really know too much about turbos. It has a GFB stealth bov one of the ones that you can adjust the venting noise level, it was fairly loud so i went to adjust it down to see it was already set to the lowest setting which should have no noise. But i still have the bov noise, what am i missing?

To the best of my knowledge mate you will never get a bov to be completely silent

does it vent to atmosphere or plumback into the air intake?

[kaino]

Setting it to the lowest noise setting has the trumpet blocked of completely, leaving it to plumback into the air intake.

How much boost you running?

Ive gotta turbosmart plumback and its still loud but thats when its dumping 20+ psi of pressure

[mad082]

if you have the stock bov on and a pod filter then you will get the bov noise, simply because the sound is coming back out through the pod. if you want it to be quiet then you need to put a stock airbox back on

Ok well that makes sense then as i am running an apexi pod.
