<VV> Thermal Barrier - Ceramic Coatings

[Geoffrey Johnson]

Hi All,
A few notes on my current motor after reading others experiences.   I did 
not take into accout 
thickness of the coating in relation to effect on compression ratio, 
figuring it would not be enough to play a big role - right now just 
playing 
around with a spare car.    I did CC the heads along with careful port 
opening and smoothing and very thorough deflashing.   This was done a 
while back before 
coating the chambers.  I actually increased compression on this 
motor by 
using 110 heads. 
It was a 95 and I 
retained the 95  889 cam.    This was rather expiramental and if it does 
not work out I have no trouble swapping them back.    I have about 400 
miles on the motor now and I am very pleased with it as a daily driver. 
Only ping I got 
was after its first  highway run when I lugged it too much leaving a light 
up a hill.   A lot may be the cam and head combo, but I am impressed
with the performace.   Good usable torque anywhere in regularly used 
driving 
RPM's.   Feels like a good 140 but it is not peaky.

I also appreciate all the other input from people who have done this.    I 
am still working on a 140 PG for my other four door that will get the same 
coatings.   It will also have a high quench setup with milled pistons.
