Regarding BPV noise on a s/c, for what it's worth, you will hear the BPV a lot if you are at anything but WOT. Being that the s/c is belt driven it is making boost almost all the time. If you are not at WOT, the BPV is bleeding off the extra intake air pressure. I had a Comptech s/c S2000 before I got my Z4MR and it was the same way.
