I dont know....I guess I have alot to learn about this turbo set up I got, I have been reading up on it and that one part just doesnt make sense to me, I mean I hear em' all the time and I never see these guys stalling or cars dying all over the place, just a nice clean BOV sound. I will find out somehow...... , how hard would it be to just switch one out anyways? any welding required? or is that just bolt on?

depends on what method you gonna go with. you can weld the bov to your existing hotpipe, or you can just buy a hotpipe with a flange already attached, like the pic I provided up top.

Ahh k now i understand. SRpowerd, its not venting the compressed air that cuases the harm, its the sudden extremely rich AF ratio's that do it, as the unburnt fuel passes through your exhaust and into the atmosphere. However if you have a SAFC with your dec air set correctly it shouldnt be much of an issue i would think. Or a stand alone mapped correctly.

good call, i actually didnt think of it that way. youre exactly right. and having a gutted cat would make it that much worse. although, these warm winters are kinda nice.

Sorry of this is a noob threadjack question:

But from what I'm hearing, it's typically better to have an SAFC before installing a Vent-to-Air BOV? Otherwise my car will have trouble compensating for the lack of air. Yeah?

eh... you can do without, but I do recommend a SAFC. Air/ fuel tuning pwnz.

yes, a safc or some other sort of air flow corrector that can modify deccelleration settings.
