Ported and polished intake manifold
Am halfway done porting and polishing my intake manifold, from the entrance of the 80mm throttle body, the the full length of the runners on the inside, to the metal lower intake. The metal piece has been polished to a mirror finish, and has come from 3.9mm to just under 4.5mm. The plastic runners I also managed to polish up pretty well, they're nice and smooth again but noticably wider. I also posted pics of the metal piece just rotated, so you can see just how much meat I was able to get from both the runners inside and the metal itself. I also have the LLT engine, so my ports are O shaped rather than D shaped, which was much easier to work with. Still need to finish up the entrance, and then do the other half of the manifold but it's coming along pretty nice
