Update: Just a misc. info note. Last time my previous setup went to the dyno with the factory X-Ported blower, it hit 19psi, with a 2.30" upper/9.45" lower. The new setup with Maggie (but also CAM / heads) hit 19psi with a 3.5" upper/10.32 lower. This week when they replace the upper with a 3.25" and go back to the Dyno, I will post that boost number also. It might be usable info for someone!
