deals with Thermodynamics plus' and where and what to Ceramic Coat,
not just Headers ,but intakes ,Piston's ,Piston Skirts,Combustion
Chambers,
Exhaust Ports
Not to cast doubt on what I believe is advanced technology but there are
some caveats to thermal coatings.
A well respected engine builder here recently went through a new 502
crate motor for a customer. At the customer's request the builder added
some upgrades to the engine, including thermal coatings on the pistons
as well as other internal surfaces. About 1,000 miles later, after
break-in, the customer was experiencing fairly high oil consumption as
well as increased levels of noise from the engine. I got so bad that
finally he (within 2,000 miles) returned the engine to the builder for a
look-see. That motor was literally worn out. It was as if someone had
put a fine silica sand in the oil. The only items that could be
salvaged were the block, (needed a .030 overbore) the crank, (had to go
to .020 under) and the rods, (which needed to be resized). Everything
else was junk including the rockers & guides. All of the parts were
sent back to the coater (well known and also advertises in several
enthusiast publications) & they went .....goodness! And that's all they
did. Absolutely no follow up and no response or effort for any relief
no matter how well the blame pointed in their direction.
I know and lots of others know that thermal coatings are the way of
the future but there are burns out there so choose wisely.
