I found a pretty interesting site: http://herpetology.com/dsm/bov.html

The guy says that if you connect the second smaller port on the Greddy type S to the turbo outlet pipe , the BOV will react quicker and it will be Louder?

Anyone ever done this? I'm gonna try it out tommorow.

 

I also read something about this...let us know how it goes.

 

It's a little louder. I don't particularly care for it though. But to each his own
