anyone know roughly how much vaccum pressure a 2 stroke 800 makes? im runnin bov that came w a r&d carb turbo kit. it looks like a tial bov w an unpainted spring. from what i understand that spring should be good for -11psi or so. my issue is the bov is open at idle and id like it shut. it closes as soon as i snap the throttle, but from what i have read to tune a bov a small amount of flutter is desired with small snaps of throttle and it should fully open while letting off throttle in wot. right now i dont have any turbo flutter and the bov being open at idle is a concern now because i have got some condensation in the charge tube. what bov and springs r u guys runnin? thanks.
