BOV vented back into the turbo inlet or BPV, is there a difference?

I already realize that it doesn't make sense cost-wise but other than that is there really a difference?
Sorry to bring it up...looking for knowledgeable answers.. and yes, I have been searching past posts.

I'm pretty sure they are the same thing...

by definition a BOV releases the air into the atmosphere and a BPV puts the air back into the intake.

if your talking about the greddy type S, hks racing, turboXS valves (except the RFL), and the like..

they're the exact same thing as a bpv just vented to the atmosphere. most BPV's are not adjustable (tension), while most bov's allow u to adjust the tension so the engine will not die on you, and also for high boost applications.

so if you vent to the atmosphere u pretty much have a BOV, if you vent into the intake u get ur BPV.

i don't see a big deal...it's your car do what u like. the audi is actually my first turbo car that i havn't ran a BOV on yet...
