Ceramic Coating or Header Wrap

[Nitr0EngiE]

I bought some heat wrap and stainless ties then found a shop to ceramic coat my manifold for 130$ in black, so i will return the heat wrap and ties which was only 30$ and i got a turbo blanket for 60

my question is how well will the ceramic prevent the heat from going into engine bay or was header wrap still a better option.

[I Love Brownies]

ceramic coating inside and out > header wrap any day

[Nitr0EngiE]

they dont want to coat the inside

they said there is too much risk of it coming off and ruining the turbo because they cant get line of sight completely inside the tubing to apply it evenly

[superskaterxes]

ceramic coat is mostly to help keep heat IN the mani to keep exhaust velocity high.

Both

[Nitr0EngiE]

so is it gonna give me the effect of cooler hood temps or will i still want to wrap it.

UPDATE: I just wanted this information to be noted somewhere here on forum so i figure ill put it here where i asked about it

I had my manifold ceramic coated and i went with titanium DEI header wrap and the effect is literally to the effect to say it Eliminated engine bay heat .... the difference is 80% its fucking crazy i did that and did turbo blanket and wrapped dp in wrap too and the heat is like literally GONE

DO THIS DO THIS DO THIS WORTH IT

[breakfstincluded]

Just to note: For DP: my ceramic coater also advised against coating the inside, and that on a turbochaged application, the inner coating will just dissipate anyway.

They also said they can no longer guarantee a product after being wrapped, something about cracking possible that I didn't understand the logic of and will probably ignore after research. They claimed it was safer to do one or the other.

BTW I googled "Ceramic or Wrap" and on a Maxima forum someone said "I would coat it, then wrap it, and coat it again" http://forums.maxima.org/all-motor/6...x-headers.html

I cannot tell if he is kidding.

They would charge 75 for Corksport Genone DP, the divorced wastegate design gives more surface area. A more typical Upper DP would be cheaper to coat.

[BigRedSpecial]

Why one or the other? Use both. You already have the wrap.

[06Speed6]

You dont need to wrap the mani if the coating is done right, there should be very little heat escaping. The reason you dont wrap a ceramic coated header is because the wrap absorbs water and the water causes corrosion as the ceramic gets hairline cracks and it also causes uneven heating from the wrap being more wet in some areas vs other areas, all of which leads to cracking.

[BigRedSpecial]

I wasn't aware of that, thanks. I do know with ceramic coated exhausts on two strokes you can lay your bare hand on the pipe after hours of running.

[breakfstincluded]

Stopped by Corksport today to pickup o2 socket and donut.

Asked for their opinon and derek did not reccomend wrapping headers or exhaust on a daily driver because of durability/strength. But acknowledged the heat control advantages of wrapping, he said it'd be better left for your race car.

FWIW I used the DEI ceramic coating from Advance Auto on my DNP manifold and I have been VERY happy with the results. For $10 a can it was more than worth it.

just to clarify you're talking about this stuff right?

Bleeeh, you get what you pay for.

Yup. I did some online searching and found nothing but good reviews. So far so good. No peeling or cracking and temps are about the same if not lower than what they were with the heat shield on the stock exhaust manifold.

[duappleganger]

So to recap, Ceramic may be better for a daily driver because it has a lower risk of causing cracking, and a wrap might be a bit better at insulation. The two should not be use din conjuntion because the wrap could absorb water, causing the ceramic to develop cracks underneath.

[LOZ]

Correct! Just use the DEI coating. I used it on my TII RX-7 and it was a night and day difference as far as under hood temps go

[foodtime]

Sorry for thread digging but anyway use Ceramic Power Liquid ? A dealer is down the road and lives by this engine additive.

Who does the coating? Additionally which coating?

Yes I know it is a dead thread don't care need to know because I am looking in the PDX area

@xxdjfate76xx;

Im spraying cerakote with good results, we are currently testing a ported OEM exhaust manifold that is ceramic coated. Off the bat I can say that the product has a very nice quality look and adhesion to the manifold. We also coated the hot side of a bnr stg3 and a gtx3071.

[Nitr0EngiE]

Years later I will tell you the dei ti wrap was way more effective than the ceramic coating, and the ceramic just flaked off and is worthless.

To be clear this was professionally installed real ceramic I paid to have coated.

[BigRedSpecial]

My manifold is coated with Jet Hot 2000*, wrapped with DEI Titanium, then coated with ceramic paint. The wrap makes a huge difference over just coating (all subjective unfortunately). The ceramic paint makes zero difference but it seals the wrap to keep water out.

I'm guessing if I were to unwrap it, the Jet Hot will be in rough shape, but it isn't as effective so I don't really care.

Swain Tech has said even their coatings won't insulate as well as a proper wrap, but they advise against wrapping over ceramic simply because the retained heat may cause the metal to expand faster than the ceramic can cope with.

[Nitr0EngiE]

Yah I was using the wrap over ceramic but there is no way the ceramic alone would have had the same hood temps reduction as the wrap did. And I have this feeling the company knew the ceramic would come off and that's why they did not want to put it inside the manifold

[BigRedSpecial]

Could very well be. As I mentioned with Swain, they said their coating should withstand the heat (It's 3000* rated), but may or may not withstand the expansion. It might very well be fine, but it's an expensive lesson if it isn't

[xxdjfate76xx]

It also depends on the process they use to cure/apply it. I've seen shops just sandblast and coat, which is improper. The pieces must be out gassed at a certain temperature for an hour in the oven. Then cooled off and cleaned. Cast iron especially is porous and absorbs oil, at high temps the pores push out the oil. This can cause cracking and flaking to any ceramic paint in the market.

[Chimmike]

I'm gonna be doing the ceramic cerakote on my turbine housing and exhaust mani AND wrapping the exhaust mani.

what I wanna try though, is the heat dissipating cerakote on the IM and the intercooler. Or maybe just the IC. Ceramic IMO keeps too much heat in.

[BigRedSpecial]

A little off topic, but this is the heat I have to tackle this winter:


From my snowmobile. The manifold and turbo are inches below the intercooler, and what heat they do manage to shed goes directly to the drive clutch and belt.

Heat blankets are available, but they're insanely fucking expensive. My plan is to get a blanket for the hotside, and DOUBLE wrap the manifold and exhaust to keep the heat to an absolute minimum.

I'm thinking the manifold is cast, so it should be fine. NCE about the exhaust, since I want to upgrade to 3" anyway. Everything will get a coat of ceramic paint to seal it, since this dirty fucker loves to spew oil over everything. Good thing four strokes are so much cleaner

[breakfstincluded]

[xxdjfate76xx]

I'm wondering if full curing the ceramic, then coating the silicone DEI spray, followed by the wrap would work. The silicone can act as a barrier for the water so it won't crack the ceramic. Worthy of testing

[BigRedSpecial]

The way Swain explained it is the moisture doesn't cause the cracking, the different expansion rates do - the moisture causes corrosion after the ceramic cracks. The way they explain it also sounds like a whole lot of "Cover Your Ass" to me.

Of course with the differences in expansion due to material, alloy, thickness etc. plus the huge variability in how the wrap is applied, it's all a crapshoot anyway.

If I swap out my manifold I'll probably remove the wrap to see how the ceramic looks underneath out of curiosity.

I'm in.

Don't spray a coating on top of the ceramic coat. Ceramic it then wrap it, and it should be just fine.

[zeroecco]

My plan has been to find/get a turbo blanket and a full ceramic coating. Based on what I am reading though, a wrap and sealing coat of high temp paint is the best on the DP and manifold.

Any turbo blankets around for our K04?

What about the stock heat shield? Would a heat blanket help there as well?

I am thinking as little "under the car" time as possible here (I have no garage, no jack stands, and live in the land of eternal rain Portland Oregon).

The NASTY thing is that my BATS are horrific and am trying to figure out how to help manage the heat soak.

[BigRedSpecial]

If you look on Amazon there are a ton of heat products from DEI, Thermotec etc. They make universal "trim to fit" turbo blankets, header/manifold blankets, etc.

I actually bought the header blanket to use on my manifold but with the ceramic and wrap the heat is minimal anyway; diminishing returns and all that

[xxdjfate76xx]

@gingermike; my concern is genpu hood scoop and rain. Lots of water easily makes its way back there trhough the scoop when front mount. How long have you ran that setup with no issues?

Also I believe the quality of the wrap makes a big difference as well

[Chimmike]

Ceramic coat will protect the metal plus what makes you think and moisture wont evaporate due to the heat?

I don't recommend putting a boot over exhaust housing mine is now warped and leaks where it mates to chra due to to much heat from turbo

I had dei turbo blanket won't do it again if I replace hot side
