Header coatings?
I finally finished the headers for my turbo project and I need to have them coated because they are mild steel. Do any of you turbo guys have the silver colored ceramic coating on your headers, and how is it holding up. I have seen jet hot coating fail on headers on non turbo motors, so I'm a little worried about using it. A local high performance coatings company said the silver coating is good for about 1300 degrees. They also have a coating good to 1500 degrees, but it only comes in flat blue or gray. I'd like to use the silver coating, but don't want to risk having the coating fail and go through my turbos. Thanks again.

I have a blown 396 in my C4, and its tubes are a dull grey as well. I am going to recoat them this year for a new engine build. This time I am going with the dark grey or the black ceramic, as it is good for 2000 degs.

You are going to want Jet-Hot's 2000 degree coating on anything pre-turbo. The extra heat and pressure that you are trapping in there because of the turbo will eat that stilver stuff up. For the downpipe and back you can use the normal silver coating.
This is how I got my stuff done and I've actually seen my header glow red hot in one of my dyno videos and the 2k degree stuff didn't come off. I haven't used if for a long time, but it seems to work so far.

It should reduce underhood temp. I have not getting my pipes back yet. Base on what they advertised you can touch the pipe without getting burn othervise. The coating .015 thick sand like and is white in color.

In no way does the coating affect the exhaust turbine wheel. That thing chews off alot bigger stuff than the coating. The silver high temp stuff works fine on the exhaust housing of the turbe but due to the high EGT temps it wont hold up on the headers.
