    Two Blitz Dual-Drive BOVs, with stiffest springs, as close to VeilSide 100 mm throttle body (1100 whp motor) as reasonably possible:

    On my car I have the TIAL BOV and it is mounted fairly close to the TB...and to me this makes the most sense as once you let off the gas pedal the TB closes and that is the first place that air stops moving forward and has to move backwards....So in theory you want it to be able to release at the closest point so having the BOV as close to it as you can allows that air to escape very quickly...However my buddy has the same BOV mounted on his hot side pipe right before his intercooler and it works just fine as well. I have a 76mm turbo on my car and he has an 88mm on his... As far as brand I am TIAL all the way man..best quality and sound you can ask for.

    I've always loved my Turbonetics Raptor BOV, which will be replacing my SSQ soon hopefully I ran it on my Mustang for a while.
    I would switch over to a piston style (pretty much anything other than the HKS SSQ style) since they vent more air if you are worried. I doubt you would need 2, but it’s all up to the person. If it lets ya sleep at night then add another one. Not going to hurt at least.
    If you really want to vent some air you can always get a Mad Dog 104.

    Engineers @ Borg Warner knew what they were doing when they put a BOV on the turbo... So did Toyota near their turbos, etc...

    We're splitting hairs in this thread, lol.

    You're neglecting the fact that both of those "technologies" are using recirculated BOVs. Toyota does it because they use a MAF system, which needs recirculation. Borg Warner does it to make consolidate all components of a turbo system into a single unit (namely turbo, BOV, and waste gate).

    I'd say you could argue either way. You could argue that placing the BOV near the turbo would allow you to keep more boost built between gears for drag racing, and placing it closer to the TB would place less stress on the turbo if you don't care about boost between gears.

    In that case I'll post up some more pipe welds. You can also see my two TiAL's BOV's, one on the hot side and one right before the TB.

    Haha, yeah a lot of the Procharger and blower guys need em. I’ve known a few people running 3-4 50mm BOV’s on their race cars. So much air it forces itself past the throttle plates etc, and doesn't let the motors rev down, bad feeling at the end of the track lol. It’s crazy to see guys at idle with the BOV’s way open hissing air out.
