bov?

A compressor surge, typically, causes an abrupt reversal of the airflow through the unit, as the pumping action of the aerofoils stalls (akin to an aircraft wing stalling).
they have websites that have sound clips of different bov.

not necessarily backwards, though it can. yeah that sounds like compressor surge jsut for the fact that the sound lasts so long
however, i think its a tial BOV. and just to prove my point (but my buddy has one on his DSM they sound very nice and unique) here is a vid http://youtube.com/watch?v=tXqgTtHECnk
sound is the last half

That's surge up the yinyang on the 240sx, there isn't a bov. Take a look when the motor is on the dyno. There is no bov there anywhere on the piping. It's straight compressor surge is all you're hearing. Go to a D1 meet and most of the pro Japanese drivers do not run one either. Their cars make the same exact sound. I know Taniguchi does not run one for sure.

nooo... wastegates dont make noise when you let off the throttle, they open only under full/near full boost. and they just open exhaust into the atmosphere if they have an external dump tube, and they just sound like a louder more uncontrolled exhaust tone.
