I come from the honda world... things have a reason.... my question now would be... is there a reason why one would want one over the other? from what i hear TurboXS RFL Bov is the loadest, and i've seen a couple of people with Hks and the Forge... but why would one choose one BOV over the other? is one better for speficic applications then others? and, what are the advantages of a 50/50 setup, other then a 100% atmo setup? are all BOVs adjustable? ...???the most used bov's for the wrx are the Hks SSQV Bov, Forge Bov, GFB Bov, TurboXS RFL Bov, and Worx Bov.
