that's a fairly loaded question, but all things being equal, probably a 25 to 35% increase, depending on proper tuning and how much breath your turbo has left.

25 to 35%? no way...not unless it's a bridgy or something. When quoted accurately and performed well, the average streetport adds 10-15% power. I'd say if you have 400 now then 440-450 should be attainable with a nice port.

even 15 % is a big increase i think...thats like 60hp on a 400hp car..that would be great..

What kind of CFM increase would you expect from a streetport.. Anyone flow there ports before and after..????
