now 3" pipe is only 424.1. so if im not wrong what people have always said is wrong. the NA Z not having a lot of power really maybe all these 2.5" dual CBE's are hurting us cause the openess is to great and the scavaging sucks. maybe this CBE does add good power because the smaller flow rate is keeping the scavaging up better.

am i crazy?
