Depends on what the manifold is made of. I would never wrap a Ebay manifold. Now, if you get a quality one, Such as this than you should not have to worry at all.

 

I was looking at that I think I found one that is not external gated what I need, I will buy something buy this weekend

 

Make sure its stainless. Wrap retains water and could rust up a mild steel product. Muscel car guys have had this problem for awhile they. Need to be changed out seasonaly.

I run Tims manifold on my car, the thing is top notch A 1 work.

 

The EE how much did you pay for those? send me a pm cause I could not ever find those cheap!

 

Well really a quality tubular header isn't cheap, you get what you pay for. Look for quality not price.

 

T3 Manifold: $775 shipped
O2 Housing: $319 shipped

Those are the current prices.

My manifold was one of his last that is DSM Flanged. I think I paid around $850 for the pair.

 

I gave up wrapping mine, The only reason I did was to keep the hood from melting. It doesn't even get warm with it unwrapped so I left it that way. I need to clean it up with some steel wool tho.

 

I wrapped my Evo 3 16G turbine housing and O2 housing and wrapped my Evo exhaust manifold. My reason for wrapping was to lower underhood temps and to help retain heat for a bit more spoolup speed.
Now as for speed,the spoolup was not a dramatic increase but it does spoolup 100rpms sooner. Like I said, you could live without wrapping it if that was your main goal with wrapping.
Now for underhood temps, I have to say this is a winner. Temps did go down and my purpose in wrapping the turbo was to limit the amount of radiant heat to the water pipe that runs behind it. I also placed heat shield tape on the waterpipe. Well water temps went down a few degrees and idling with the AC on my temps stayed a steady 192-195F. Now for oil temps, I noticed that if I race the engine and I'm spooling, the temps of the oil starts climbing real fast. I'm thinking due to my turbo being hotter.
I'm really happy with the results. To prevent rust, I coated everything with the silicone spray that is used for the wrap. I also sprayed the wrap a couple of coats for added protection.
So just from my experience I have to say that if you are running tubular, you can't put a heat shield on top of them like stock. So this wrapping would help.
I agree with WOZ. Make sure its stainless. I plan to do wrapping on my next turbo (FP3052) and since I'm getting the custom SS 3" recirculated O2 housing, I think this would help with radiant heat.
This is my opinion.

 

Is that how you get them looking good again? Mine has darkened quite a bit and I would love to get it looking nice. Its weird, my o2 housing stayed looking perfect.

I want the carpet to match the drapes.

Wow Work of art. Really nice looking setup. I don't know if you was directing your question to me, but the silicone spray I bought was Silver in color. It was really nice because it had a very high amount of aluminum flakes. Really silver, more than the high heat silver you would get from Rustoleum high heat paint. I wanted to waterproof the parts because its a DD and it will be subjected to the elements (Humidity, rain etc)

 

My question was aimed at K_Mans_TSI.

I am still thinking of wrapping my manifold. I have the wrap in the garage just have not done it yet. I did a little of the manifold because it sits close to the valve cover and I dont want to melt the VC gasket. I was thinking of getting the custom fab shop near me to make me a custom heat shield for the manifold but I am not sure if its worth the money or effort to make because the spacing is that tight. As you can see in the picture.

 

That is what I have done in the past, yes.

Ok, Thanks bro. Going to have to run out and get some steel wool and spend the rest of the day cleaning the spots I missed on the engine bay... as soon as I am done replacing this stupid idle pully and redoing the timing.

 

wow one of the far best manifolds i have seen. I had a ss autochrome manifold..the only reason i used it cause i got it for FREE. After a couple of months it cracked so i went back to my evo3 gt manifold.

 

EE, why wouldn't you wrap an Ebay manifold? I would assume it would give it a bit more durability, but I guess I assumed wrong. Just seems like the other way around...hmm.

 

There's always ceramic coating. Dont use the chea[p stuff though. so far ive had VHT and DEI chip and flake off. Also EE you could get some 8mm bungs welded on runners 1 and 4 and mount a shield off of those

 

I had thought about doing that but honestly, the engine bay temps dont get too bad. With the lack of a condenser for the AC, it gets plenty of air flow in there.

 

I'd wrap it, it can't hurt any. Lower the temps the better!

 

The reason I would not wrap a Ebay manifold is because its not stainless, the welds generally suck more than my ex GF and the usually make them out of a couple different metal types, so I have seen. From what I understand, two different metals heat up and cool at different rates. Because of that, they expand and contract at different rates which can cause them to crack. If parts are wrapped and others are not, it can speed up the cracking of the manifold.

The Quality of the construction and materials plays a real big part.

 

I would wrap it but it is a hot manifold though

 

I wrapped my Evo 3 16G turbine housing and O2 housing and wrapped my Evo exhaust manifold.

How do you wrap an exhaust housing without it looking like trash?? Or a cast manifold?

I would assume it would resemble taking your hand, putting it in a fist, and wrapping toilet paper around it.

 

No this isn't my car and yes the car is 10 throws up a cats ass.
Example:

 

OMG haha that is horrible! Here's my 2g manifold that I wrapped all to hell. After running it hard I can still touch the top of the manifold I wrapped it so much.

 

Damn they mummified that manifolduke: wow. Thats a quick way to blow 50 bucks
