SMOKE at high rpms's what si it?
 

The smoke looks whiteish and it only happens at high rpms. I noticed it at the dyno today it is not a lot by any means but the guys there said it could be from having an or y pipe no cats or condensation. what do you guys think?

it only happens at around 6k rpms. My oil is not milky so probably not blown head gasket. My coolant looks a bit rusty but it always has due to radiator rusting I think, also I am not losing any coolant at all. could it maybe be bc of having no emmissions equipment on the car? no cats, egr, air pump? please help me

it could be from not running any cats but im not really sure. it sound more like a head gasket is starting to go even though the oil is not milky.

the car will run rich at high rpm, so it's normal to see black smoke coming out when you get close to red line
