Hey all,
got some quotes from HPC and thought i'd share. prices are GST inc.
4 cyl headers, coated inside and out, in polished ceramic finish $187. thermal wraps are not recommended on top of the coating.
Pistons $33 each. adds 2.5thou to top of piston and 1 thou to sides, so slight change in dimensions.
for heads, combustion chamber $33, ports $11 each, valves $11 each.
HPC also say that there are no thermal expansion problems between the coating and aluminium.

with the question do they wear? some times yes some times no , every engine is different , the way people put engines together is different. We have seen and got pistons out of V8 supercars , Drag cars etc and they have been excellent. With pistons that have problems with the top ring lands , that can be caused by detonation or running to lean in the cylinder , not by the TBC
|
so, the bottom line is, for $396 i can have ceramic coated piston, combustion chamber, valves and exhaust ports!!! (i wouldn't bother with intake ports)
i reckon i'll have to do it next motor 
fwiw, at uni i work on TBC (thermal barrier coatings) for jet turbine blades. the coatings are around 50-100microns in thickness (0.05-0.1mm = 2-4thou) and reduce blade alloy temps by 100-150deg C (ie allow higher running temps of 1150C vs 1000C). as long as these coatings stay on, they should work well!
Cya, Stewart
