Agreed, outside is not a great idea. However, it's maybe less of a bad idea if the inside is done also, since the metal temp is likely to be lower, right? the only thing bad I can think of about doing the INSIDE is that if it flakes off it could destroy the turbo. On the other hand, if it doesn't flake off, it significantly reduces the radiant heat transfer back to the cylinders, which according to some guys in Ada is a good thing. ...and since I haven't been able to fab those little reflectors for the exhaust stacks I figured ceramic coating the inside would be a reasonable alternative. In theory you get a little more power to the turbo also. Colyn
