Ceramic Coated Manifold Data

How durable is the coating? Think you could use it on the exhaust runner and combustion chamber? Should help with detonation in turbo application. Keeping the heat out of the m20 head should also help keep it from cracking.

Very nice!
I am also surprised to see the increase in surface temp after coating!
I assume these are coated inside and out? -
iR thermometer doesn't work on "shiny" did you take actual measurements with a surface probe? Without knowing the "e" of the surface and dialing the IR to that e value you can't directly compare especially when the coating is changing the e on purpose. I've temp'd metal pipe that is 300f but reads 120 because it's averaging in the reflection of the room.
The coating looks awesome. How tough is it and could it be used on wheels?

That's interesting to know. I'e been using an IR thermometer to measure rotor temps for years now. I think for his purpose right now he can still measure with an IR therm and gather results based on variances.
Why would you want to use this on wheels?

If the coating is harder or has a satin or matte finish that is unique it would be cool. Also maybe it adheres better for a more reliable rim seal

Hi Andrew, thanks for the info. I will do some research and play with emissivity values that may correlate to higher accuracy results on my next experiment. The coating is more durable than I anticipated it to be, though I like to put a generous surface profile on the parts I prep. It can flake off if it gets chipped. It is a lot like the green coating on brake hard lines.
I dont see why it wouldnt work on wheels although a rock chip would make it vulnerable to flaking moreso than a more flexible enamel type paint

I've been using IR thermometers for years. You just plain can't measure the temp of a mirror surface for and example. You will be measuring the temp of the item in the reflection. To measure a soda can for example you have to put on a piece of tape. Same for ductwork. A surface probe thermocouple would be the accurate way to measure but an internal probe into some thermally conductive goo of some type would be a decent makeshift. Only trial n error you can get an accurate e value for the different surfaces but once determined should work well. High temp tape should work well
