Not technically blow off. The “stututu” is turbo flutter, which happens when air flows backwards through the turbocharger as it’s pulled back in by what are, essentially, vacuum forces. A BOV is supposed to keep this from happening, as it can cause wear and tear on the turbos. Not a perfect technical description, but hey, I’m not Engineering Explained (shameless plug)!
I do love the noise though. My S80 doesn’t have a BOV, so I get turbo flutter on occasion. Surprises the hell out of other enthusiasts; nobody expects the Swedish turbo guy,
T6 :) very nice broh, I have D5
I think that having turbo flutter off-throttle won’t wear the turbo out significantly more than normal, but compressor surge on-throttle is much more of an issue.
Well, I did know it was “turbo flutter”, I just wanted to refer it to “Stutututututu”. What about blow off valves?
Bwaaaaahhh psshh bwaaaaaaaahhhhh pssshhh
Everyone likes that noise lol.
Pzzzzhhzhzhzhzhhz
