can a cast manifold be powdercoaded to a chome like finish?

[DROOPY209]

I have a SBR cast manifold with the external wastegate flange on it.

I'm going to either polish my stock intake manifold, or have it powdercoated to a chrome like finish. I already have a polished valve cover also.

I was wondering if a cast manifold can be powdercoated to a chrome finish, or what can be done to it so that it looks polished.

Yes they do have powder coating that are shiny & chrome like but they are usually only rated to about 1300 F. I have seen some rated to around 1600 or 1700 but they claim they will lose their shine if taken above around 1300 as well. Most of the higher temp rating coatings (2000+) are a mat finish & don't come in the chrome look your after. I have seen a few guy on here that had the chrome like coating on their mani's, so it would be interesting to see what they got & how it is holding up to the heat.

It will start to dull and discolor

Have you ever popped your hood and looked at your turbo after some hard driving?

..talk about Glowinf red-hot....I would go with a tubular Stainless manifold if you want the "bling" ?

x2 if you want the bling. I have seen the copper gasket stuff used. IMO it looks nice. Gives it a penny look.

Just put the stock heatshield over it, and trim the spot where the wastegate flange sticks out. This piece alone brings underhood temps WAY down and it amazes me how many people with stock or stock-ish manifolds don't take advantage of it! Not to mention the manifolds rust or even if you coat them look like crap after a month of abuse!!! Just put the heatshield over it, and if you really want you can polish or temp-coat the heatshield.

I had mine ceramic coated, Obviously it's not been on yet. It is not supposed to keep the nice shiney look. The coating is really only to help it retain the heat.

jmfabrications polised heatsheild FTW

Heatshields FTW period

 

[DGajre777]

I would paint it with some VHT 2000 and get a JMFabrications heat shield.

There is some very good advice in this thread. I too would recommend the use of a heat shield. If you don't want to run a JM Fab, then you could opt to have the stock heatshield powdercoated to a chrome-like finish. I've done both in the past and had success with both.

You can Jet-Hot Coat most items. A good friend of mine did his manifold, exhaust housing, and o2 housing all done in it. Looked great.

 

[dnhieu]

Do you know where he got it from? do you know how much it costs?

 

[fourreGsixty3]

Heat sheild FTW!!! By the way Steve I love your VR4, I cant wait till this summer when you bring it down to one of our meet's. The ceramic coating looks good. What also looks good is a manifold painted flat black with high temp paint(2000*F), with the JMF polished heat shield. Their heat sheild is only $45 too.

Just curious, did anyone see a drop in under hood temps when switching from OEM or the JMFab heat shield?

i also would like to know this. i have never ran a heat shield before and am thinking about running one again!

 

[Street Surgeon]

The JM Fab is a nice looking piece but I doubt it keeps underhood temps any lower than the stock piece, something to do with the stock piece being two or three layers leads me to believe that it would function better but I don't have any numbers to quantify though. Maybe someone else with a background in thermal dynamics will pipe in here.

 

[gixrman]

I don't have a background in TD but I know that it is benifical to keep the heat in the exhuast manifold to help with ex. gas velocity. When ex. gases cool they slow down. The stock cover I believe is better since it is shaped to the manifold with a layer of fiberglass between the metal.

You also want to seperate it from the comp. housing so a nice shield shoud go there also.

He, looky over there! Why, it's the Thread Topic!

A chat about heat shields would be fine, but let's do that in a heat shield thread.

 

[Street Surgeon]

This is pertinent to the thread at hand, or do you not see the relevance? Should I have started a new thread to answer his question and give him my advice to not powdercoat the manifold to a chrome finish but use a heatshield instead?

 

[IslandTSI]

Nah lets just clutter up the forum for no reason. That seems like a much better idea.

 

[Defiant]

And here's an even better one.
