el cheapo, i just installed mine and.... it makes that noise (on stock boost) not sure how it will go on 16psi but it should be much louder. Got them of ebay they are selling some more, check out there site belowBOVsRegards MaxP.S. This is the one i got
The splutter is NO bov, If its what I think you mean, its a fluttering type sound, caused by compressor surge (bad)
well my bovs dont make that whoosh noise but they make a different noise, hard to explain and if i could should record it. Maybe next time i am on the dyno. I do hope its not compressor surge but i dont believe it is, maybe its to do with the trumpet i got on it.Max
Actually the flutter is caused by some BOV's we just put one in a mates skyline, and played around with it and it makes that splutter sound. I always thought it was the cooler but it seems that it can be made different ways. Also when i had 3 boost leaks 'vacuum hoses not on at all' i was getting this flutter sound.
The one i want makes a unique pitch that sort of makes a fluttering sound it is not like your standard BOV's misfuncioning or compressor surge. i have heard it on a couple of differn't cars around town. It doesn't have a real high pitch like the HKS super sequentials but it is up there.
