Using a Barnant 90 digital thermometer (type K thermocouple), I ran hot air* thru an uncoated header part I had and then ran the same test thru the similar coated part
Ambient temp= 75° uncoated= 230° ** coated= 141° ** *industrial hot air gun, 1500watts, temp range 750° to 1000° F **five minutes run time, measured ~.25" from surface why the dark coating instead of silver, I guess I like my engine parts just like how I like my women (IMG:style_emoticons/default/smile.gif) seriously, the black coating was recommended by Specailized Performance Coating for my particular application (future turbo installation) Attached image(s)
