My understanding was that the bOV opened to let air into the turbo when you're not on the throttle to keep the turbo spooling.
While we're on the subject what's a everyday turbo , that I don't have to worry about detonating my motor with? Responses greatly appreciated.
Technically, when the bov vents 100% to atmosphere, there isn't air going back in. The turbo is suppose to be spinning freely at the time, which would help the turbo spool quicker when shifting (at least that's what I've read). But most (ok, all) people haven't noticed any increase in performance.
