Looking for Pro/Cons ceramic coating

[TDIDog]

Ceramic coating exhaust and turbo housing as opposed to wrapping. Any & all thoughts. Was thinking of wrapping headers from heat boxes to turbo housing. Objective is mainly under hood heat. thanks for in put.

Anybody have any thoughts?

It works go ahead? Looks purdy. Wrap would possibly retain some moisture against metal where ceramic is not wrapped.

Just off the top of my head I would say ceramic coating will not provide any heat shielding. Wrapping would, but there is the issue of trapped humidity with corosion potential.

[TDIDog]

My headers are stainless, so moisture shouldn't be an issue.

I hope some experts will chime in. But for heat shielding wrapping should make a big difference, IMHO. And moisture trapping with stainless steel components in the generally hot engine area should be almost nill. Humidity is always driven out of warm or hot areas. Anybody with experience in wrapping exhaust components out there? I do remember having seen it mentioned somewhere else in this tech section. Maybe you want to do a search.

Was thinking of ceramic coating the turbo & exhaust pipe as well. That is supposed to help too as far as I under stand. Some expert thoughts would be good.

If you are going this route then ship parts to swaintech. Lots of people wrap DP's on their cars to reduce heat as long as the dp is stainless. I did on my Saab and it’s pretty remarkable how much it decreases under hood temps, plus it's supposed to decrease spool, but I didn't notice that.
I ceramic coated the old Porsche muffler I had using black Satin (2000 degree) and my main gripe is that it scratched very easily.

Do a google search. Not much on here but it's cmon and one of the main bennifits is undergo of temps and keeping heat inside the exhaust.

ive done both in the past and there are pros and cons to both.

I like the wrapping because it was cheap, i could do it myself. i hated the wrapping because i drive my cars year round which means dealing with the elements i.e. rain, snow and is a pain in the ass if you get oil on them, they dont look as nice obviously.

I liked the coating because it looks clean, keeps the temp down, dont have to worry about dealing with the elements, oil is still an issue as some coatings will just absorb it (dosent effect anything but, the visual imperfection is there), price is substantially more obviously.

Just because something says that it is stainless steel you might want to check to see if all the welds are as well and what grade it is.

They scratch easily....good solid pipes is a good thing....the stuff works but is soft against abrasion, impact and other bumps and grinds.

what you really want are ceramic exhaust ports - ceramic on the headers will provide a much much smaller benefit, esp. on a N/A motor

air cooled Porsches have a tendency to leak oil. When oil gets on the wrap, I've heard of fires starting.

In my Subaru days, many people would ceramic coat the exhaust manifold, uppipe, and exhaust side of the turbo. Those that did reported much faster spool up times. People that ceramic coated their exhausts themselves could pull the pipes out from their grill with their bare hands.

Wouldn't ceramic coated exhaust ports be a major risk with a turbo - say if the ceramic comes off, and some of it will, it will go right into the impeller wheel . . .

[RWebb]

sure!

Did 964 Turbos use the ceramic liners? I know the naturally aspirated ones did, or was that the 993?

Wrapped the exhaust on a 1600dp in my old bug. Every time I would work on the thing the wrap would get oil on it, and it would take forever to burn out. It was annoying and pretty embarrassing.
