Ceramic Coated Intake ?
I was thinking of using Jet Hot to ceramic coat, just the top,
no insides/bottom/portsides, of my intake. I figure it would have that polished chromed look and and perhaps even act as further heat barrier. Has anyone done this to an intake ? |
 This setup was on my Cobra when I bought it. The 'entire' intake is ceramic coated and it ran much cooler than the single polished aluminum edelbrock I am running now. I would assume the reason was due to the coating. Gene |
There are companies that specialize in coatings for applications like this. They put a reflective coating on the underside to keep heat out of the intake, and a black coating on the topside to dissipate heat. Don't have any names or numbers though.

Ceramic Coatings
I have the intake manifold coated on the inside and out on my blower motor. The manifold runs very cool. This engine is in my truck that I use for towing. I also had the pistons ceramic coated and the skirts of the pistons coated with a dry lubricant. I have never had a detonation problem even when I accidently put mid grade in my tank. I had all my ceramic coating done by HPC in Salt Lake City. I changed my cylinder heads at 15000 miles and the tops of my pistons still looked like they just had been coated. If I would do it again I would get my valves coated and maybe the combustion chambers. When I worked at Kirkham Motorsports we did that to a 427 and it ran very cool.

Entire engine ceramic coated ?? WOW, that would be cool...Can you ceramic mechanical parts like brakes and rotors ??
couldn't you ceramic coat your block, crank, rods, pistons, heads, valves and intake ?? Seems to me it would make for a much smoother, cooler running motor with more hp ??? That would also be longer lasting...But I could be dead wrong... |
Why would you want to thermal insulate all your engine (or brake) components? You need you engine parts to be able to rid themselves of heat by transferring it to the oil. The coatings that they put on piston tops and combustion chambers are different that those on the exhaust. Ceramic exhaust coating can and does chip off too.

Yeah those are the guys who's name I coudn't remember. Notice they use three different coatings on intakes alone: Bottom is heat reflective barrier, top is improved emmissivity (heat loss), inside runners for lower friction. One coating does not fit all applictions. Anybody out there try nitrocarburizing on gears, cams, or what-have-you? Burlington in the name of a company that does it.

Thanks for the website Jeff ! Great guys !
I am on the phone with Swain as we speak ! They recommend a satin black coating for the intake they say dissipates heat off the intake when used with their inside thermal coating. Full thermal treatment is about $450. They advised against outside ceramic coating stating it actually keeps heat INSIDE the intake. At the least I may send them the intake to have the botton heat barrier treated for $110. I would like to maintain a shiny look on the intake. |
I have my sidewinder intake coated with HPC's silver finish ceramic and it is very easy to keep clean. I don't know if it helps or hurts the perfomance but it sure does look nice and doesn't stain (at least easily). I am swithing to a single plane edelbrock and coating it along with the expansion tank (try keeping paint on that for any lenght of time) the timing cover, alternator body, remote oil filter adapter, etc. All in matching and lasting coatings. Do it and you will not regret it!

use the cryogenic process on the high ware parts..www.300below.com

Here's my intake, which I will use again on the next engine....It was done by finishline coatings in Oregon. Topside ceramachrome and bottom black.

Really nice piece Brent !

FYI
For the inside of the engine, after cryo, some racers are using dycronite (sp) coatings. For more info you can call Norm at Westech Auto 262-889-4346 A dry lub is often Moly that has been cooked onto the skirts of the pistons. Sometimes a light cross hatch is used to add depth to the coating. |
