how much HP can be gained with adding Ported Intake & Ported TB to a Z with killer bee, headers, and cam?? can the PI & PTB add more than 15 rwhp?

Mine gained 11 peak rwhp.

Unless you are doing the heads and cam, the HP gain would be very minimal

depends on who's doing the porting. My 09 Z06 tuned with 160 stat and a honker CAI made 480rwhp/437rwtq. The tunning was done at RPM motors. After Charlie ported the intake, the car made 500.3rwhp/457rwtq without a ported TB or headers. A lot of so called tunners say they will port your manifold, but all they do is grind plastic out of it and turn it into a paper weight. So Far Charlie is the only one who flow bench test every port and has the knowledge to complete the task correctly. Poof is with my numbers. So be carefull who you have do your work. As a side note Charlie gets a lot of maniflolds from people
Who've had there manifold ported and don't work, and there's nothing he can do to fix it. My opinnion, but my numbers speak for themselves.

do you think these gains are coming mainly from the intake?
