As said above, go the bosch plumb-back BOV, flows well and is killer value! I have used one plumbed to recirculate and later to vent and it worked well. I know of a particular 8 second car in Canberra that uses more than one on his car (more than one to achieve greater flow, my turbo could just about sit in the bell mouth of the turbo this thing uses!!). So apart from not looking trick ie polished/anodised aluminium they are quite good.

As for the what d-shiznit wrote about the compressor wheel slowing down and makin the so called "chika chika" noise when the throttle is closed, isn't this due to the wastegate, BOVs and wastegates work differently, BOVs release pressure in a sudden rush where as wastegates release pressure via slowing the compressor wheel down, thats why investing in a BOV can usually maximise the lifespan of a turbo, most if not all turboed engines come with a stock WG. Someone please discribe this in better detail or correct me so I might get a better understanding.
NO NOISE IS GOOD NOISE!!

I am not getting into the whole noise thing again as this was discussed a couple of days ago in another post at length.

But just to clarify that the wastegate allows exhaust gas to BY-PASS the turbo exhaust wheel when the wastegate is partially-open to fully-open, thus less gas is passing through the exhaust wheel and it's rpm is limited, and because it is solidly attached to the compressor wheel boost is limited.

The only noise a wastegate makes is a slight increase in exhaust noise when open (very very very little in most cases, usually just noticeable inside the car to a keen ear) or if a "screamer pipe" arrangement is in place on an external wastegate a large amount of extra un-muffled exhaust noise is created.

I have only ever seen one car with no wastegate, the owner had simply welded the wastegate shut and let the car do it's thing Rolling Eyes

Not a great idea I don't think, it sounded rather unhealthy on the dyno.
