You would be surprised just how much that turbo acts as a muffler. When idle or cruising my turbo and sc were about the same. But open them up and my exhaust on my sc is stupid loud compared to what my turbo was.

I thought we were talking about which had better sound not which was louder. Two separate things completely.

Oh. Turbo sounds better at WOT for sure. Sc wins at idle and light throttle. I've never personally heard a better sounding turbo than the bp kit wide open.

I guese from my perspective is idle...and light rev driving through a crowd or parking lots the supercharger is more noticeable ... In real world driving is much more often ... I mean even though we would all like it ....we can't be WOT all the time. Lol

I'll agree with that. I also think the BP kit sounds better than SCer during unload.

For sure. A bov is a much nicer sound than a bpv. Even if it's just a second long.

Id trade all turbo and centri sounds for that sweet F1 whine of a roots though.
