Anyone know how costly it is to ceramic coat a six cylinder header and if it's worth the money? If not a ceramic coat any other suggestions?

I didn`t do my Healey but I had my airplane exhaust done by Jet Hot Coatings and they still look great. I had them done in a nickel finish but they will also ceramic coat anything you want. I had the piston tops ceramic coated and the skirts done with a dry film lubricant. I had the exhaust valves done with the ceramic coating too. I have been pleased with the results. Skip
 
Hi Mr. Pit,
Headers, as opposed to manifolds, were $195 plus $27 to ship back to me.
 
Thanks for the feedback Skip & Greg

Greg did you have yours done on the West coast in Washington if not would you recommend who you used, how's the heat difference, will it ad to the life expectancy and what's your dogs name?

Oops, I forgot to say that I used Jet Hot also. They have a couple places, so they will give you a shipping address that’s closest to you (if you use them). I like the finish (Sterling), it goes with the other shiny bits in the engine bay. Haven’t run the engine yet, so I won’t comment on heat reduction or other claims. If I did have a dog, I might name him Otto, for no particular reason.
 
Hello Money Pit, i can reccommend the ceramic coating, i had the downpipes on my BN7 done many years ago by Jet Hot (when they only had one place to send your stuff) and can say it was worthwhile. It keeps more of the heat inside the pipes which means less heat under the hood. Go for it regardless of the cost, it'll be worth it. Regards, BUNDYRUM.
 
Cost me about $225.00 including shipping. This is not the first time I've done this, and like Skip, I too have been using the full compliment of polymer thermal barrier, thermal dispersant and dry-film lubricant coatings when building my engines. Unfortunately, the last time I went through the Healey's engine (1987?) they weren't yet available to the private sector (NASA technology transfer from the space shuttle).

So, what's the advantage of coating the headers?

Keeping the heat on the inside of the pipe keeps the escaping exhaust gases at a higher temperature maintaining velocity for a longer time period. That improves cylinder scavenging and subsequent charge filling each next time the intake valve opens.

And you only thought it was for looks?! /ubbthreads/images/graemlins/wink.gif
 
I stopped and looked at mine this morning on my way from the house and the part of the exhaust that is under the engine cowling is done in a black thermal barrier and the exhaust stacks that extend out of the cowling are sterling. I had forgotten they were not all sterling but the entire exhaust is s/s and looks brand new after about 450 hours running.

Those look absolutely stunning. I bet they look even nicer when mounted and in the car. Good choice /ubbthreads/images/graemlins/cool.gif

Thanks!
 
Had my Seven headers Jet Hot coated. In addition to the other advantages, I am sure the footwell is cooler.
