#12259, "RE: easy recirculation mod for HKS SSQ" In response to In response to 14
Originally posted by eclipzGST I thought the bottom nipple was the one that helps it open correctly under low boost. I read somewhere that you can leave the bottom one capped unless you're getting surge and then you can tap that to a manifold source to help "push" open the valve.
Right! The lower nipple helps it open under low boost, meaning you can tighten the screw on the BOV MUCH more than if you capped it off. You can tighten the BOV a lot to stop it from leaking, but it will not open at lower boost. If you actually use the lower nipple to help it open at lower boost, you can make the BOV harder to open so it doesn't leak at higher levels That way you get it working at all boost levels.
