Somone with more experience wanna clarify that for me? Performance advantage/disadvantage of plumback Vs vent to atmosphere BOV = none. Vent to atmosphere if you want the sound louder or if plumbing it back into your intake is too much work for you. Correct call on the overfuelling between on boost gear shifts of AFM cars when a venting to atmosphere BOV is used. The severity of this problem seems to vary from car to car though from what I have seen (partly dependent on how much air the BOV can dump in its puff). Some people don't seem to mind a small puff of smoke (unburnt fuel) and a backfire to get the pssshhh sound from there BOV on an AFM car, I personally wouldn't do it. Just be aware that the supersequential BOV's do have a different sound (not a flutter though), which is hard to describe. The only example of this type of BOV that I can think of that lots of people have probably heard is it sounds like the BOV on a WRC car (when you can hear it over the antilag ). I have only seen a few cars on the streets with these types of BOV, I wouldn't mind one but they are pretty expensive. As a side note I went for a spin in a friends car the other night and his BOV wasn't venting unless he absolutely gunned it. He is going to be fitting a lighter spring, the compressor surge was very loud and it doesn't do your turbo much good either. [Report message to a moderator]
