Turbo Manifold has been added to our website. It'll be an additional $1,400 to upgrade to the DOC Race manifold. Come snag yours today while our end of the year turbo kit sale is still going on!!

We have used ceramic coating on the manifolds for quite a few years and really like the results we've gotten this way as far as exhaust temperature is concerned. The coating decreases that transfer quite a bit, the wrap tends to "trap" the heat in the metal from our experience.
I have notice this as well but there is one down fall using ceramic coating on a turbo applications. Most Common Ceramic Coating can handle up to 1300F until it start to burn off, and start loosing performance. There is also different type of Ceramics can be used as well that will handle up to 2500F

Doc Race - Could you tell us who do yall coating? What the Specs?

We coated this turbo manifold. Over the years we tried several coatings from several companies and all of them except for this one have deteriorated. We finally found a coating that withstands all of the abuse our customers put them through and it's been on all of our HPF turbo kits for the past 4 years. Underhood temps are extremely cool with the HPF turbo kits and this is one of the reasons why. Go to a track day and check out the underhood temps after an HPF M3 does a 30 minute session. Quite amazing.

What's the temp difference between coated and non-coated?

My understanding is the issue with ceramic coating is that the metal will fail a lot quicker since all of the heat is trapped inside of the pipes. Any idea on the decrease in lifespan?

I'm asking because you guys probably have more experience with this. Just wanted to put that disclaimer out there so there are no mo' deleted posts.

bigjae1976: With our ceramic coating experiences, we've tested surface temps of manifold tubing while loading the vehicle on the dyno and have seen temperature differences of over 500 degrees. That data is used to reference radiant heat in the engine bay.

As far as the metal failing; ceramic coating is applied to the inside of the manifold as-well as the outside. Doing this reduces the heat transfer into the tubing, which increases the life-span for heat cycles. How far or long, we haven't had a controlled test to gauge these specific results/comparisons.

E85head: We have a few different vehicle setups that are getting fitted with our Tubular Manifolds. We will be quick to share results as the cars come back together and get re-tunes!

E85head: There's a few cars that are awaiting built engine installs along with the tubular manifold. Also another customer that hasn't pulled the trigger on the install of the manifold as-well; all I can do is tap my foot at this point!

I am currently moving and don't have any intention of installing the turbo system on my SMG (stock engine reference) until i'm settled in about April.

I will be sure to update ANYTHING regarding results on this.
