Ok, so I understand how they both work. They both work differently, so this raises the question, which one is more effective on a low-boost application? I'll be using a FMIC'd T25 in my EJ9 civic. (link in signature) I'm planning on a recirculating BOV, to let the turbo free-spin instead of surge. If I do this, I need a wastegate, right? If I use an atomsphere-vented BOV, then can I get away without using a WG?
