Filtering a Blow-Off Valve (BOV)

BMW 335i Twin turbo is fitted with Synchronic BOV. We show why some cars don't even need to be filtered. An efficient turbo will be discharging air at idle like a centrifugal supercharger and will always be discharging air when the BOV is open at idle and cruising speeds

under vacuum the valve will stay open,and discharge air.. not suck in air... the turbo is sitll spinning,and creating positive pressure... just not enough to over come the vacuum. i dont understand what people thing bov's suck in air at idle or in vacuum.. for that to happen the turbo it self would be spinning backwards... use your brains people.. think how things work before you post

@nine3cobra Agreed....

Hmm, the BOV is discharging air at idle, and yet the engine is still under vacuum during idle and not boost. Seems to me that you have a leaky BOV because all of that air should be sucking through the throttle body during vacuum, and discharged only when boost pressure is being realized....

you may want to do a little research on how a bov is actually supposed to function cause that thing is all sorts of messed up

Only a BMW owner would ask a question this dumb. Try building ur own car or at least learning how the fuck shit works instead of just putting a bov on cause it sounds cool....

why would a BOV even suck in air?
