Adjusting Type S BOV?

[B0oStEr]

I fitted a Type S plumb back BOV to the factory location in an auto R32GTSt.

I hooked up the factory tube to the fitting on top of the diaphram leaving the fitting below the diaphram open.

The problem is that the new BOV can't be heard operating at all.

It's either super quiet or not operating at all.

I've backed off the spring tension a bit but it made no difference.

Do I need to hook up the lower fitting to boost before the throttle body.

Can I connect it up to a T piece in the actuator line or is there somewhere better to hook it up?

Do autos need a different BOV setup to a manual?

Does leaving the lower fitting open to the atmosphere do the same thing as the 'blocking the hole in the bottom of the stock BOV' mod?

Are the copies of the Greddy typeS bov on eBay any good?

I was under the impression that Greddy Type S plumb back bovs make no sound because they do not vent into the atmosphere. A guy at autobarn told me that you gain some sound if you have a pod filter as well.

so its a tam ko type s? you cant hear plumbacks very much maybe even less so on an auto

are you saying there is two spots on the bov to hook up the pressure line from the plenum?

I had one and it is louder then the standard bov,well i reckon.It fluttered on low boost and around 8-9psi is where it worked,this was plumback to.I left the bottom nipple with nothing connected.Also I had the tention about halfway.
