Been thinking about the benefits of having the Exhaust Manifold, Turbo and Dump Ceramic Coated on my TD42Ti build and wondering if anyone has any experience they can add to this such as improvements before and after, costs, shops to use etc.
My knowledge is basic and logic focused until I learn more about this. EGT's are obviously a major concern especially at the piston crown which is why we monitor them, however most sensors are placed at the dump which is not a true indicator. When modifying engine and Fuel/Boost it obviously makes sense to look at upgrading cooling be it water or air intake and exhaust. Ceramic coatings will protect by lowering, and stopping such big and rapid swings in temp in critical areas under load. This apparently keeps heat in the ehhaust and stops it soaking back to head and engine bay, so I imagine it will be good to maintain longevity of head and minimise hot spots somewhat.
As an aside in regards to Stainless exhaust and dump is there much difference in the use of Stainless due to it's higher melt point, in that it will be more stable at the running temps, or is that minimal or negligible.
At this point I'm considering manifold and turbo as engine is out, it may not happen given timing and factors out of my control but it could be done later, if it's worth it. Will be running 30 PSI and 200 RWKW.
Interested to hear peoples thoughts on this and thought it would be a good topic to start
