Ceramic Coating Engine Parts

[Anonymous]

Have any of you guys used ceramic coatings on engine parts such piston tops, valves, cylinder walls or anywhere else in the motor. I've read the JET-HOT website and basically they put it everywhere where heat and friction are factors. I was just wondering the performance of it in the sixes. Also, I'm pretty sure the increase in temperature in the combustion process due to the ceramic being far more effecting at containing the heat would increase detonation, what's your take on all this?

8) actually the coating decreasethe tendency to detonate as the ceraminc absorbes the heat and reflects it evenly in the cylinder. detonation occurs when you have a hot spot in a small area. the heat is also prevented from being transmited to the incoming intake charge, as well as the cooling system. this is but one of the ways race motors are making as much power as they are these days.

Rumor has it that they are the actual manufacturer of the coatings that most shops use. They sell many of their products retail, also, for home shop users.

I'm preparing to use one of their thermal barrier coatings on chambers, valve faces & exhaust ports & manifolding of a 23.5:1c.r. turbodiesel(with intercooling & propane fumigation). Reasons: keep the heat out of the coolant, in the chamber for more power (& fuel efficiency), and in the pre-turbine exhaust tract for better turbo spool-up(& hopefully, less heat in the cab!).

If it feels right in that already-in-use diesel, I'll probably disassemble my built-but-not-fired 300BB6 (turbo & intercooled EFI) to do the same coatings(piston tops, also), plus TechLine's dry-lube treatment to piston sides, cylinder walls, valvetrain & oil pump.

I have also been thinking about the Techlinecoatings brand for everything from the valve springs to the crank.
There products make a lot of sence and there are a lot of OEM and Racing parts that are coated with these products.

Now I still have a lot of questions conserning proper cylinder wall finish and how you use it on valves. But I do believe that we have a lot of drag in these motors and that these coatings will help.

I have heard of the benefits before but hadn't seen any hard evidence on the coatings. Thanks for the site J.R.! I used their approved applicator locater and found out one of their approved shops is right over the mountains in Auburn. They have estimated price lists on their website and the prices aren't half bad. I'm definitely gonna be calling them about my internals. The longer I can make my new engine last the better. It's gonna take me even longer to build it this way but I know the thing will last alot longer.

8) for pistons and valves, most shops machine the area to be coated the same amount as the thickness of the coating to be used, leaving a lip around the edge to keep the coating from chipping.
