alright I'm baffled???? We just installed the Turbo XS type S BOV on my brothers 240 and it flutters alittle almost like compressor surge. My question is what are these suppose to sounds like? Does anyone have experience with these bov's ??? Thanks H-T

 

another guy on this board had the same problem with a greddy bov, try adjusting the screw sound like it's loose.

 

Mine sounded like that on 5 psi and it was sort of gay. Now on 10 psi it still does the same thing but with all the extra pressure it sounds much cooler. I could adjust it but it's still allowing the pressure to be released so I just leave it.

 

Be Careful a bov that is to loose can also be a place for boost leak.
