Intake Manifold Coating

[Mystery Bird]

...the underside to aid in preventing heat soak. I've been thinking of doing this or sanding and polishing it so the oil doesn't stick as easily. Has anyone tried either method? I've read about it but don't know anyone that's done it on an LT1.

Truthfully, unnecessary IMO. You can probably do a thermal coating or something, but I wouldn't sand the bottom of it smooth. You'd be removing surface area by doing that, i.e. less head dissipation.

[Stephen Ertel]

I have a thermal barrier coating on the underside of my stealth ram, and a thermal dispersant on the exterior surface. I can rest my hand on the manifold and it is just warm to the touch immediately after a drive. As long as there is plenty of airflow it keeps the manifold cooler than uncoated, however once heat soak sets in it gets just as hot. I needed the exterior of the manifold coated after removing the coolant crossover, so I just picked something mildly functional. Compared to my intake, there is much less runner length on the LTx to disperse into the intake charge, however the plenum gets directly heated from the lifter valley where mine is isolated...

Fastbird - Sanding the underside would reduce surface area for heat to be ABSORBED by the intake. You're right for the exterior of the manifold.

Edit: Don't forget the gasket mating surface where it meets the head, ALOT of heat is transferred in this area and there it a benefit from a thermal barrier coating here as well.

Please, tell me more about this.

Do it. I use all of the techline products

Some good reading there. Thanks!

First...I love the advanced section. I have thought doing this. Like putting gliptal in that valley but my only concern if the paint chip and could it do damage/clog the oil pump or other ports.

I would bet as long as the heat shield is in place on the bottom of the intake, you'd get better results than sanding, polishing, and coating the underside. It would keep the hot oil off of the underside (which, I bet, is why they put it there in the first place ;) ).

theres alot to be had in coatings check out swain tech in upper state NY ive done some of my parts with them.....it works nicely if your looking for every last hp.....heres a pic of my pistons they did for me

Thanks for the tip on that location Mike.

[firebird_1995]

I think we have a sponsor that does all sorts of coatings....

[Mystery Bird]

We do?

x2 on every little bit helps. If it didnt we as LTXers wouldnt push for every last 10th / HP / TRQ / et / mph / etc...

I did my piston in the nic ind. gold

Did my valve faces , stems, head chambers , runners , etc.. bearings , lifters , etc.. anything that could be coated with one of their products I did.

[firebird_1995]

We do?

I dont know what other sponsor does but see my sig.

I shy away from headers anymore but will do em.

I do pistons , head chambers , valves , turbos , waste gates , intercoolers , piping , etc..

[firebird_1995]

I was talking about you.

Tapatalk doesn't show sigs so I didn't know if people knew that or not

[FSTFBDY]

I was talking about you.

lol, ahhh.. I was wondering since I don't have an banner/add on the site.
I think /thought someone else did also.

On my converted Supervic, the whole base was cut out and replaced with a carbon fiber heat shield to help prevent the intake from getting heat soaked. I am also making a template for my own Phenolic intake manifold gaskets using the Felpro SBC Race gasket. Hoping to virtually eliminate heat transfer into the intake.

While it may not be easy to quantify exact benefits, I feel the right coatings can be beneficial to a performance engine. My lifter valley was done up in POR15, and my AFR's runners and chambers have gotten the full treatmeant by PolyDyn(Ceramic in chambers and exhaust runners, oil shedding coating on intake runners).

Sikora had the CF intake valley and Polydyn work done when the heads and intake were his, and I chose to do the POR15 for oil drainback and the Phenolic intake gaskets are going to be my little experiment. Want to test the intake surface temp with a laser thermometer at operating temp with the standard Felpro gaskets then the custom ones.

[Mystery Bird]

I've also been thinking about a custom heat shield on the underside of the intake.

Let us know how the gasket test goes.

Can you do black ceramic(not sure what coating that was on the turbo)? What part of FL are you in?

I might have to hit you up when I get the exhaust for my Ninja. Getting black or carbon cans and want the mid-pipe black to match :). If I decide on a full system then I would want the header done too....

[FSTFBDY]

Yes its a black ceramic.
Im in SW FL. (North Port)

Bike exhaust is doable. I use to do work for basaani coating stuff.
