[Land-speed] Ceramic Coating

[Karl Payne]

I run a Ford 4 cyl turbo motor in a very small engine compartment.  Before coating, I used to melt wires regularly.  Went to a ceramic coating of the turbine housing and exh. manifold, voila; no more toasted wires.
  I used a local flame spray house, used zirconia for the coating (actually it gets welded to the substrate via the flame spray process) because that is what is used in some parts of jet engines on the hot side.
  Pricey, but I swear by it.  Plus it looks nice an white, never discolors, chips or flakes off.
   
  My $.02, YMMV.

  Anyone have any experience with the amount of heat reduction in the 
engine compartment with ceramic coating the headers? Is it more or less 
effective than wrappings? Can you wrap the coated headers then take the 
wrapping off and clean the header? Thinking of keeping the engine area 
in a rear engine streamliner as cool as is possible.
