Greddy Type S BOV

[Twisted99]

I have just install the greddy type S BOV in recirculation mode on my MS3 and am wondering what the second vacuum nipple in the middle is for? It seems to be sucking air from it but their is no connection for it. Should it be sucking? Should I plug it?

Anyone have any experience with this BOV?

I had a greddy type s on my integra, and I had one of htem plugged. I was blowing off though.

Plug the other nipple.

you dont need to plug it. on some cars you can hook up that smaller nipple to a positive only pressure source, such as directly from the turbo. it will make the valve react faster, and allow you to run a tighter setting. it is not needed though. just leave it alone.
