Hi Paul, it was Phil who said that, and I too, agree with him. I started this thread exactly because of this: since its easy to screw up.

Tell us why the porting in that pic is wrong. It's not my head, and I didn't do the porting btw, I just used a pic from the turbobricks forum. I would not do it this way either which is what I said in the first post: Grind just a little bit in the top, so that the wall will allready steer the flow outwards instead of just towards the ceiling of the port (this is not done on the head below)

But please tell us what is beneficial and what is not, so we can learn.

cheers
