Hey, I was just wondering if anyone is running a Bypass valve (such as bosch) with a blow off valve as well. I have searched, but not found exactly what I am looking for. Would this method even work, or would it be too much air loss? Can somebody explain what this would do? I am only running stock boost by the way.

I think high boosting cars do this or 2 bov's so one is better for the high boost and one is for the lower boost.

oscar, how much boost are you running, and does running a BPV with a BOV render the same effects of an vent-to atmosphere, or does it run fine?

I have my bosch and my SSQV. SSQV is still pretty loud, purpose of the bosch is to vent some air back into the intake to keep it from dieing less often.

Im running a Greddy Type S and a Bosch BPV.....as others have said, it helps with running rich in between shifts, and got rid of my backfireing when I let off the gas quickly.
