maybe one of the engineers here could post the formula for velocity. I will dig up some books tonight to get some guidelines. I picked up acouple of sets when Jamie did. Since the 3.3 has 32mm ports, porting them to match 38s seems like the right thing to do. For a turbo, you want the velocity to reach a certain # much earlier in the rpm range. Then let the turbo pack it in. I will post the formula tomorrow if nobody else does.

Jamie, keep up the good work!
