Anyone have experience which would work keeping the heat in the pipes better and not in the engine bay?

Well I can tell you to jet-hot a set of turbo headers it will be about $300, turbo housings are around 75 each when I got my quote for 2000+deg

I'm going to be using header wrap because I'm making new 304 headers so no point in coating my current ones right now.

I've heard that header wraps trap in moisture and make the pipes rust really fast. I have no direct experience.

Well ****, mild steel rusts fast as hell anyway, and that is a huge bonus to ceramic.

Thats also another reason I am making 304 headers from some of the research I've done ceramic on 304 is pointless - it would be nice to hear from someone that knows how much of a difference there really is

on stainless no, mild yes.
course mild rust anyways, dont know the difference on how fast one rusts wrapped to unwrappped.

It makes for problems with aftermkt headers, as some mfgrs will void your warranty, if they are wrapped.
The wrap holds the heat in the tubing, and can concentrate it to a point that the materials are affected in a negative way...

As for ceramic on stainless... WHY NOT? The idea of the stainless is to better stand the elevated temps, especially that of an FI engine. The coating holds the heat rejection down, and lowers the under hood temps by a significant amt.
The results?? The best of both worlds, so to speak. More durable headers, and less heat in the under hood area.

As for the wrap... It makes a great wick, when oil soaked.

unless when you need to weld on your coated stainless cause of cracks, thats a pain to strip off the coating before welding.

get it in get it running get it wrapped...

then later on in life id get them coated..but get it on and all worked out id do that...
onec you do your first intalll tske the tti street kit apart and back in is easy!

chuntington101

well i would get the headers coated inside and our! thsi reduce the heat stress on the stainless and reduces under hood temps! then heat wrap just to be safe and to reduce temps even further! then you could even add a heat shield!

thansk chris

PS anyone multi layer the ceramic coarings???? i have heard of it being done!

Id rather not have to take it all back apart again. This is my only car too. I have another one I could drive, but its a PITA since its my work truck. I dont want the couple week down time

Country Boy

I wouldnt get the inside coated. I wouldnt want to risk it flaking and send stuff into the turbine....

How much mositure can the wrap hold? Wouldnt it all burn off when you drive it? I didnt like the oil and wick comment though.. LOL

chuntington101

Country Boy, as long as you get the costings done profetionaly at a shop the does all the right prep work then you will be fine!

and the internal coating really helps! it smooths out imperfections and drematicaly reduces the thermal stress on the header itselfs (heat has to go through the coating before even getting to the metal)! and just doing an external coat will lead to even great thermal load on the headers as there is no where for the heat to go!

thanks Chris.

oh i forgot your talking about the tti street kit, IMO dont get it coated, youll eventally have to reweld the cracks on the log, and its a pain to strip off the coating to weld. just wrap them, its 304 stainless so it wont rust.

Country Boy

Why do they crack? Is it the heat expansion or the weight of the turbo?

I was wondering if coating with ceramic on mild steel then wrapping it would be a good combo ? The coating would keep it from rusting right ?

Yes, I have seen this happen. Bob

Possibly for a while, but I wouldn't do it unless you just want to experiment. Bob

You'd have to check w/ whomever you have do the coating to verify, but I'm pretty sure most advise against it and will void the warranty on their coating if you do.

heat expansion mostly IMO
