New FM ceramic manifold and outlet casting
So my new parts came in today. The black looks cool, but seems to be non-uniformly applied. Anyway, I took some pictures of the inside of the manifold and the casting as there are some pretty rough casting marks in there. Should I bother cleaning it out or am I going to mess up the ceramic coating I just paid for?

Some places coat inside, some coat outside, some coat both. The inside helps retain heat and transfer it's energy into the turbine, creating a quicker spool. Outside is all about keeping heat from the engine bay.
I'd just go ahead and clean it up. Sad that they left a rough casting and then coated over it.

maybe this was my impression from the begi kit. Man, I wish I would have asked FM about this now :( I know the Begi kit is internally and externally coated. According to his book, it keeps more heat in the charge which theoretically spins the turbo faster since you have one more thermal medium for the heat to pass through. I don't know how much of an additional benefit it is, but it sounds cool. Well I guess I am going to have to wait until I get some time to clean this up before I mount it back on the car. I just wish this stuff would come ready to put on. You would think for $800 in parts they could get rid of the casting marks. Oh well, off to buy some attachments for my dremel!

As for casting imperfections, my BEGI mani was cleaned up after it was cast, it has normal casting marks but the ports were cleaned up substantially.
