Wrapped Header rust faster........mythbusted.

[transzex]

You can see where I didn't wrap, and where I used it as a skid plate :)

Interesting.....Thats very nice to know now :D Thanks for the info

[SilverCiv]

Why was it not wrapped completely?

[NastyHabitzCRX]

not so much rust as they crack when wrapped. did my DC 4-2-1 and in 3 months one of the herges cracked.:beer:

[shifty35]

Retiring the Stillen eh? Let's see some pics of the Dynatech on!

[sohcvtec420]

Rockin the wrapped Dynatech!

damn that sucks!

[SilverCiv]

hmm black wrap looks sexy^^^^

[The_Acid_Beaver]

Wow, I didn't know they had colored wrap now!

Stainless is more suceptable to cracking if one uses cheap header wrap. Most 3 series stainless steels have very low tolerances for chlorine, which causes micro-fractures in the structure of the steel, which lead to macro-fractures when thermal cycling is applied.

If you want to make sure your headers last while wrapped, make sure you use the more expensive stuff (like it is THAT much more expensive) that doesn't have anything that contains chlorine in it.

Just for the record, I have seen fingerprints and sharpie marker marks DESTROY 304-ish stainless steels. Just something to think about . . .

If the DC in question was mild steel, then I don't know what to tell you other than that really sucks. Mild steels are less susceptable, but not immune to cracking due to chlorine corrosion.

[transzex]

Right now I'm rocking OEM B7 mani trying to get the bitch to fire.

Dynatech will go in with the D15Baby8 motor, the black wrap looks sexy!

[mikeD16Z6]

heat wrap rocks!! I used it on my old ssauto manifold.... still shiny underneath :TU:

[ryan89crx]

repost! i remember seeing you post this probably 2 years ago :wink:

[Henklin]

When I had my manifold wrapped, gravel drive ways with grass centerlines ate the lower wrap. :( I eventually just took it off. I liked it when I had it... much better bay temps.

[SOHCinWA]

I will never use header wrap. It keeps the heat in but what people dont understand is that that header will get extremely hot with the wrap on and actually they will start to glow. If it keeps getting hotter, it will actually melt a hole or two in the header. Not worth the hassle.

[myHonda1]

i like that black wrap!

[CrazyConscious]

I've had both my header and turbo manifold wrapped. I'm now selling the header and it looks fine. The turbo manifold was an ssauto and cracked where it wasnt wrapped.

Sounds either like a race motor or a tuning issue.

[shifty35]

Sounds either like a race motor or a tuning issue.

That's where high-performance coatings like Jet-Hot originated... header wraps were making headers on race motors literally disintegrate after a couple hours on the track.

[fireant]

I've been told that the cracking can happen where the wrapped part of the header cools off much slower than the unwrapped parts, and the difference in temperatures causes stress from the different rates of expansion/contraction. Makes sense?

I'm wanting to put wrap on my DC. Its in great shape, but it would be good to have lower temps. Where do I get the black wrap?

[killer_D]

i've read in jdmuniverse that it traps water... is that true...

[transzex]

does it look like it?

[kyle h.]

lols, did you use any "sealer" on the wrap or just wrap her up and leave her go?

[transzex]

nothing.........

Just SS hose clamps and DEI 2" wrap

[hocivic95]

Rockin the wrapped Dynatech!

nice job, i like the valve cover.

[H2Bcivic]

you think it woulda not rusted if u sprayed the header with high temp paint. then put the heat wrap on it and spray that sealer shit on it?

[snoborder280]

i've read in jdmuniverse that it traps water... is that true...

If you seal the wrap properly, it shouldn't be a problem.

[sheperd]

Is the DEI good wrap, just ordered some, does the white containe this chlorine people are talking about, I am putting it on ss headers.

[whitesol]

I used black wrap on my header....but the color seems to be all but completely gone from it after only a few thousand miles. Why did the color 'bleach' out so quickly?

[fireant]

My DC has a little surface rust, should I paint it with something first (like BBQ paint) before wrapping it?

[twing]

bought an egay header recently. It says ceramic coated. Should I still wrap it?

[transzex]

you like HIV/AIDS?

[d16_turbo]

Depending on the material used to wrap. (the cheap eBay wrap will not last long at all and will trap water if not wrapped properly). I had my turbo manifold on my B-series wrapped with some wrap I purchased from a machine shop (not sure of brand). Worked great and kept the manifold temp's down as well as its appearance. Never any problems. But I have seen improperly wrapped manifolds trap water and cause rust much faster.

[d16_turbo]

you like HIV/AIDS?

HIV is the SHIT! Can i get it on eBay?? :hammer:

[d16_turbo]

When you put the header on and run the car for the first time, for about a day or so you will get this terible smell from the so called "ceramic" coating. Just warning you..it will go away eventually ;) You can wrap it, but I dont see the need to IMO.

[transzex]

I used DEI wrap for that header, next setup will use something that's twice as thick and costs less :)

[d16_turbo]

Thats how I like my woman...thick and cheap...

[fireant]

I'm using DEI black wrap and the Silicone coating, I'm going to:

1. Remove, paint it BBQ black
2. Drive it with just BBQ paint to 'cure' it
3. Re-remove, wrap, paint with silicone

[slebidia]

Old news Bone. Of course maybe people will actually listen now.

[transzex]

if they did, I'd have about 1/3 of the posts I do now.

[99EJ6T]

Thats how I like my woman...thick and cheap...so let me get this right, you go hoggin?

if they did, I'd have about 1/3 of the posts I do now.true. maybe you should just refer to yourself everytime you post, like this:

click on my name and search my posts. i have posted the info 10000x

[transzex]

Thermal Zero, hopefully Shaun gets the website updated.

[oL Dusty]

I have the DEI wrap on my OBX ss header, I sealed it with their silicon spray. I have drivin over 100k with it, 10k in the last 3 weeks, 34h strait driving from calgary to toronto, and still no problems.

[1.5Slowmatic]

i have an ebay header with no wrap and so far after 10k and 7 months its workin fine. This winter will be the true test. If it goes bad, im gonna go SS.

[EP3Moschini]

I did my girls, still no problems there, I also did my DC RH on my ep3 (worth $500.00 alot more then my girls ebay header)

both have no rust yet. .

I love the crinkle red valve cover

after running my dsm hard in the summer time, the turbo manifold will start to glow. i did this several times and you know how many cracks are in it? zero. unless i saw visual evidence of holes being melted i would have to call http://smiliesftw.com/x/bsflag.gif (http://smiliesftw.com)
if you said cracking it would be plausible, but melting holes in an na honda motor header is highly unlikely

i've read in jdmuniverse that it traps water... is that true...

if you use cheap wrap, don't wrap properly, or don't use the sealer...

[transzex]

I never sealed mine.......

raw DEI wrap.

[Greddy]

Good information

[2001B18C1GS-R]

hey i have a rage replica 4-2-1 long tube header and i have 2" by 50' blakc dei wrap what should i do before and after i wrap it thanks

Read all of Bones posts...it that does not work click below.
