Port it to the edge of the stock flap.

Welding on a bigger flap is even better since you can then increase the size of the wastegate hole even larger.

but there is no BAD side of going too big?

gsracer

As long as the flap covers the wastegate hole there is absolutely no negative side affect to a hugely ported wastegate.

wouldn't that still have tons of boost creep with a 3" free flowing exhaust, and intake?

just fyi that was a usual question.

and Ryan, we ported the wastegate on a car with intake and full 3" exhaust. before the port it would see 11-12 psi in first and second (woo). After we ported it, it peaked at 5.5 psi.

Sweet. Thanks $150FC!!
