WHAt? I'm sorry I don't understand. I thought porting was grinding away at an area. He doesn't even show where he's dremmeled he's seemed to epoxy something but it's on the outside? And isn't the part that actually opens the gold coloered part? It's hasen't increased any at all.
yeash, look on the inside bro!!! the epoxy is used as a filling material, b/c in removin that tumor, you run outta plastic (you'll notice your workin at a crease in the plastic)....the epoxy is just to fill in that surface. look at the inside shots and you see that streak of white. thats where the epoxy is peekin thru. not that hard.
as has been said many times. its to increase airflow and to help cure the anemic Throttle response of the focus.
