Uh...the air on the intake side of the turbo is at atmospheric pressure, regardless of where your BOV vents to. Although your fuel metering can be upset by an atmospheric valve, the BOV outlet location will have no effect on the actual physical operation of the turbo. The turbo does not have to "work harder" to pressurize the intake air.
