Ceramic exhaust coating

[tejr]

Anyone done this on their Cerb?

Just out of sheer curiousity whilst the car is off the road I thought it might be worth a look to help drop ambient temps under the bonnet. I've seen prices of roughly £100 per bank, is this about accurate? I would probably decat at the same time to prevent super heat soak to the cats..

Just wondering really..

My manifolds are on there way to the ceramic Coates as we speak, it's well worth doing, or so I've been told.

Also had them port matched, but this can only be done on 4.5 manifolds as there isn't enough metal on 4.2 manifolds

I have a suspicion that the port mismatch was there to prevent reversion. Hopefully someone with a better memory will be along soon to confirm my thinking or contradict me.

I had mine done while they were out for welding during the last service at APM. From memory I think it added c. £400 to the bill. I know Andy sent them away and it took an age to get them back as it was holiday season. I'll have a look at the bill when I get in tonight to see if it says who did the work.

Tim at ACT got some done for me by Camcoat.

Old wife's tail I hope.

I've taken advice from Raceproved, before going ahead with the port matching

I had mine ported and ceramic coated, gained 5hp! Woo hoo!

Definately reduce under bonnet temps.

And they look cool!

Camcoat did them, I think it was nearly £400, but I paid more to get them back quickly

The Camcoat coatings appear to be more about corrosion protection/ asthetics than reduction of under bonnet temps (unless I have missed something). For the temp reduction you should look at Zircotec ceramic coating

We'll be using Zircotec coatings on the exhausts and a number of under bonnet components on RedVictor3.. Their products work very well indeed..

They offer thermal barrier and anti corrosion coatings according to their website. Too late for me to change things now as the job is done, but I'll bear in mind your recommendation for the the future.

I had my S6 coated with Zirtec. I'm not getting the 100+C temperatures that I used to in heavy traffic.

[high52kojak]

Camcoat list the 'Cermakrome' coating under the Thermal barrier heading on their website as well as anti-corrosion. It does provide a thermal barrier.
Cermakrome is the coating I had done and is one of the most popular coatings.

If it were the port smaller than the manifold then I may beleive it but as the maifolds are smaller than the ports (also the manifolds are round whereas the head ports are D shaped) I find it unlikely it did anything to prevent reversion.

Myth busted!

Other than it being under the thermal barrier section of their website, I cant see any reference to temp reduction for cermakrome on Camcoats website. I guess I'm struggling to see how a water based paint can be effective as a thermal barrier

[ridds]

Doesn't really matter how it's applied, it's what is applied. Once the water is gone you are still left with the ceramic that provides the thermal barrier.

All that the Plasma spraying does is give it a much stronger bond to the component.

I'd be more interested in what the material is they use. I've had my manifolds coated about 3 years ago by them and it cetainly felt like it reduced underbonnet temps (no data to support this though).

From some guys who run turbocharged engines at very high boost they recon the new titanium exhaust wrap is more effective than any of the coatings. I just done mine, its not cheap at around £60.00 a roll (3 required) but they assure me its better than coating. When its back in and running i will let you know. Certainly on the Scooby I saw I could touch the manifold with the engine running!

Had it on my scooby bud and it did work a treat,worth the money
