couldnt tell ya, but the most pressure is on that side. what i always thought was that the further away your bov is from your throttle, but before the turbo, you could acctually keep most of the air in your intake tract in....(get it??) cuz what i think if you put it damn close to your throttle body, then all the air will come up the intake tract and be released into the atmosphere, losing alot of air in the piping.
maybe im not explaining this right...oh well.
