i know the hks bov vents atmospherically, and produces that sounds we ALL LOVE....now my question is, can i recirculate this bov? and how drastically will the sound decrease?

 

All you need is an HKS SSQV recirculation kit:

All you have to do is remove the purple fin you have inside the valve (unbolting the outter shell by the allen bolts around the face), and boom. Routing the hose back into the intake before the turbo is another pickle because you'll want to place the discharge into the intake BEFORE THE MAF SENSOR!! Dunno if you knew that or not but just incase you didn't otherwise all is lost and you'll have the same a/f blips as with a vent type



Sound? What sound?

 

the answer to your ? was in your HKS SSQV owners manual but the d@mn thing's in japanese

 

a recirculation kit is needed as prototype_xb stated. one thing you must know is that, if you get a recirculation kit for a turbo kit that originally designed to vent atmospherically, you will need to have a small tube welded to the intake section AFTER the maf sensor. reason being is the air being recirculated is already measured. the sound will definitely decrease, not sure by how much though :D

 

by alot.
