I talked to someone this morning who recommended coating the turbine/compressor wheels (I'm not sure if he meant turbine, compressor, or both) of the turbo with teflon. He said something about the air flowing over the blades of the wheels better.

Has anyone else heard about this, or had this done to their turbos?
Do any of the turbo kits for the Z/G already have this feature on their turbos?

 

Doesn't sound like a bad idea but I'm no aerodynamics master.
