well, there is many variable in how a blow off valve might sound. They have a similar frequency, but they can vary from different boost pressure, the plumbing of the bov, how close it is to the turbo or the throttle body, and the spring tightness...

Fong, do a low-medium speed flyby blow-off (external video).
Anyone know what BOV those high power jap cars (esp the drift cars) usually use? It stutters alot and sounds like 'zooo-zuhh-zuh-zuh-zuh'

you talking about ceramic thrust bearings? (turbonetics style?)
Because most of those jap drift cars use HKS stuff and the bearings used in those are standard bearings - twice the thrust load tolerance of normal journal bearings, but only 1/20th compared to ceramic thrust bearings (40x more thrust tolerance than journal bearings)
