    Now Im confused as all #$#$! I have no idea, because there are no solid replies to yes or no when a bov should be used. Maybe that is because most Bov threads include a question about the first mod. I have read over and over about bov not a good first mod, Ok, Im fine with that, don't want one any ways.

    But, what about after you upgrade the entire fuel system,get a bigger turbo (looking at 18G), get a FMIC, some engine management, and a dyno tune all at once. Is that an ok time for a BOV? Or is it after the boost gets turned up.

    I have searched this, and everytime the question of an upgrade consisting of a bigger turbo/IC/Fuel system/dyno tune/EM, the replies are 50/50. I can't figure out what is the right solution.

    Sorry not meant to Hi-jack, but maybe some good replies to this will help out future new suby owners with a question.

    The simple answer is, if you upgrade your turbo and begin running a higher boost level than what your stock recirculating valve can handle, you simply get a stronger aftermarket recirculating valve that can handle the increased boost pressure. There are stronger recirculating valves out there ya know, so just because all aftermarket BOVs can handle a good amount of boost doesn't mean that they are your only choice once you've exceeded the capability of your stock bypass valve. The only reason why these BOVs can be set to handle a large amount of pressure is because they're typically built to be more universal in their application, rather than for specific vehicle or motor.

    With that in mind, just because you get an 18G, intercooler, fuel system, dyno tune/engine management doesn't mean that it is now OK to get a BOV. The basic operation of the system isn't really changing when you do such upgrades, you're just operating on a larger scale (bigger injectors and more fuel, bigger turbo and more air) than before, nothing more.

    To sum it up, more boost does not justify the purchase of a BOV. More boost justifies the purchase of a better recirculation valve.

    Erm, wrong thread maybe? Boost control units and BOVs perform completely different jobs.

    Brainfart - my bad. stock recirc is considered good up to 25psi I think from what I've read on the forum. - I guess the question I was trying to ask is :

    Are there any aftermarket replacements for the stock BPV which we can put a link to in this thread so that people can be referred here the next time the question arises?

    (and the award nominees for run on sentances are.........)

    Perrin has recirculating BOV


    Turbo XS also has an upgraded recirculating BOV the WS-RBV. We just got them in and they are very nice.

    Now in order for these to function correctly and not cause the car to lean out - 100% would need to be recirculated correct?

    Yup. Both of those are recirculating. But, like Cheesy said, why bother till you actually need to?

    i have the turbosmart dual port 50/50 and i could not be happier. yes, it it true that is dropped my mpg by 1 or 2 and it had 0 performance gains, but i enjoy the swoosh it makes and that was why i bought it. not to put in others faces, but for ME to enjoy when i and whipping through turns. it adds to the sensation of speed and power at a time when i am not vary fast at all. truth be told, once i get faster, then it is going to come off the car. i will have more than enough sensory input to know i am haulin' azz.
