Painting Intake Manifold?

[SilverXJ]

What did you paint it with?

[ajmorell]

Duplicolor engine enamel, semi-gloss black. I cleaned up the intake runners as well to better match the gasket. Still need to do the throttle body and the header though.

[ajmorell]

Here's a better picture. I also spent some time grinding down the runners on my Banks header today. Didn't turn out as well as I would've liked but given the limited tools I have available right now I think it will do okay, better than it was anyways.

I hope that header is still able to seal well. From the pics it wools like you took quite a bit out of the gasket surface.

No, I didn't take much at all from the flange. 95+% of the material I took was from the area where the flange meets the runners.....if I get a chance I'll post up some pics of the gasket and the manifold so you can see how the two match up. My main goal was to smooth out the sharp edge where the runners meet the flange.....I think I did a decent job of that. As for where the gasket meets the manifold, they are about equal, I didn't take off material where the gasket was present.


I guess that's what you get for taking pictures with your phone

I will probably ceramic coat mine as well as the headers, that way it will last and look good for a long time. And plan on powder coating everything else, block and all.

I think paint on the intake manifold will be fine, but it might flake off in areas where it get's really hot like near the head and near the exhaust manifold. Ceramic coating would prevent that and if I had a reasonably good way to do that it is certainly the better option.

I was looking at that again. It's deceiving in the pictures. Some of the spots where it looks like a lot of material is gone there is actually none gone, it just got bumped with the grinding wheel enough to clean it up and make it shine.

I can ceramic coat it for you if you wish, that's what we do, that and powder coating. I would give discount pricing for stroker members.

[ajmorell]

I'm not sure who you're directing that at, but I've already painted the intake and I'm putting it all together next week so I don't really have the time to be without it. Appreciate the offer though!

how does one powder coat an aluminum manifold (its non magnetic)? I was thinking of doing rims but never learned how.

[SilverXJ]

Powder coating uses a static charge to attract the powder to the part. No magnetics in play.

The powder coat it held in place via a static charge then it is cured in an oven.
Anything conductive can be easily powder coated, even wood can be powdercoated.
