is it safe? well its not "un safe", but it will most likely make your car run like ****. it wont blow up, but it'll suck to drive.
is the noise worth that?
Nope. I was just curious on what the first post mentioned. My VR4 is recirculating and I keep it like that. Running a open (atmospheric) BOV makes the 3000gt's run pig rich and I always kept my VR recirculating. Didn't want to have to throttle bump every second when I am at a light.
