out of curiosity, what bits are you using to port and polish with?
I'm debatin if I will go larger on turbo inlet. maybe I will leave the outlet alone because it wouldn't make sense if the air came from the smaller intake housing into a big ass port. it would let it expand and basically lose pressure in turn. although it might not register on a gauge. I have this whole kit I bought from summit racing. it uses a little rod that goes into my 1/4" die grinder and the sanding tips thread onto the rod which tapers at the top. I polish first with a blue sponge type deal and finish with a softer red one. I've had the ports on my 250 looking exactly like a mirror and by that, I mean I could see my eye lashes in the reflection! carbon simply wipes right off of it
