Re:1g BOV flutterbox
 

and the answer is:

compressor surge.

do to the fact that it is crushed. the bov will not open under low boost AT ALL!!the only time i got it to open was when i boosted up to 8lbs. so i put an uncrushed 1g in there and it's loud as hell and sounds exactly like a HKS SSQV/Greddy Type S. so i'm happy.

your 1g dsm bov is crushed? no wonder it wont open!! :-[ you need like 20+ psi to open those things LOL, glad you got it fixed...compressor surge...bad!!! :-X

i recomend T ing off one of the large intake manifold hoses, PCV valve, charcoal canister hose ex. get a 1/4" plastic T at the auto parts and the small clamps for the hoses and T off the charcoal canister filter for the wastegate and the PCV valve hose for the BOV, both of these are strong vacuume/boost sources.

I did that last night and didnt feel any air come out. :( Bad BOV? Its Teed into the IM so I couldnt imagine the vac source being the problem.
