I also thought it was weird that there was a spring inside the stock intake. I thought it was there just to avoid it collapsing under boost. Who knows how well that works... The closer the BOV to the intake, the louder it will be. I think no matter where it is though, you'll hear a difference. But like Yoshi said, the biggest difference will be the increase in spool sound. My Greddy Type S BOV outlet is almost flush with my recirc. bung maybe 2" away and you can hear it as if it was atmospheric. Maybe 20-25% quieter than atmospheric.
