<VV> Ceramic Coatings Questions

[RoboMan91324 at aol.com]

Gang,
 
I have been thinking of using ceramic coatings in a rebuild I  am doing and I 
have a few questions.  These are as follow.
 
1.  Since the head will be thermally insulated from the  heat of the 
combustion chamber, how will this effect the warm up period of the  engine?
 
2.  Since the pistons will be insulated from the heat,  they will expand less 
and/or slower in the cylinder.  I believe that the  expansion of the piston 
is assumed to be a certain amount when the diameters of  the piston and 
cylinder are set.  Is this an area of concern?
 
3.  The engine I am rebuilding is a 180 turbo.  Am I  correct to assume that 
I need to also coat components in the exhaust side of the  turbo to protect 
them from the increased exhaust heat?  If so, which  components?  Also, will the 
thickness of the coating cause an  interference problem between components 
and/or balance problem on the  rotating member?
 
4.  I assume that the exhaust pipe components must be  thoroughly cleaned 
before the inner surface is to be coated.  Is it  practical to coat the inside of 
the muffler considering that the inside can't be  thoroughly cleaned?
 
5.  If I do not coat the interior of the muffler, how  much hotter will it 
get with this setup and will the increased temperature  cause a problem with 
surrounding components and paint?  Also, what reduced  life span can I expect for 
the muffler if it is unprotected?
 
I guess that is enough for now.
 
Thanks in advance,
 
Doc
