hey guys i recently purchased a 87 turbo and i wanted to install a greddy bov kit on it. would i have to recirculate it or can i leave it vented. i once read that leaving it vented on maft cars usually causes idling problems. but does this always happen? i would love having it vented cause i love the sound of the greddy bov. so hit me up and let me know what u guys think.

All per Grimjack;
Ok, here's the deal.

On the Supra, the BOV is usually attached after the air flow meter. This means that any time the BOV opens, you are losing unmetered air, and your engine promptly runs very rich. Some people have had problems with it running so rich it stalls, more have had backfire issues.

There are three ways around this. In order of increasing cost, they are:
1. Live with it.
2. Route the BOV vent back into the intake after the air flow meter.
3. Move to a system that measures your air differently - like running a MAFT in blow through mode, or switching to a MAP sensor, etc.
