    They are superb but very pricey. I was quoted £150 for a mini manifold.

    Well, I went for Zircotec on my Ford small block. It's not cheap...mine cost around £700 for both manifolds! :stunned:

    The problem is, I have no before and after to compare it with, but it still gets very warm under the bonnet. I did speak with Dave Walker of Emerald while he was mapping the system. Our conclusion was that we were not sure it was any cooler under the bonnet than a compearable non coated system. I'm now looking at louvres and a bonnet scoop....primarily to give more space for air filters and to let heat out.

    So, I'm not 100% sold on coating, but maybe at some point, comparing under bonnet temps of our cars may show if it's worth it or not.

    I used VHT paint on mine however on one occasion :cursing: it got a tad too hot (red) and the paint just fell off :rolleyes:

    The car doesn't over heat but on track at ford fair I think I was getting fuel boil headers and rocker covers where red hot and fuel lines run over them even though they are insulated I think this may have been the problem I'm also looking at going to fuel injection so might end up rerouting them anyway

    I thought this stuff was so good you could put your hands on the manifold...unless that's when just idling?

    I think Zircotec coated headers cool down quicker, but even at idle, I would not touch them after a couple of minutes of running! A mate of mine said that his rally escort manifolds that were coated can be touched fairly soon after switch off, so perhaps the process is better these days...mine were done by Zircotec over 5 years ago. They were based on an ex mod base and you had to have your car searched when entering and leaving! They have moved now though!

    Heard good things about a place called camcoat. The coating is supposed to help with gas flow rather than just be a method of having reduced temperatures.

    I tried cam coat. I wasn't impressed. I had some janspeed exhaust manifolds coated inside and out, but they looked like crap after 4 journeys and a year. Having said that, it could have been down to poor quality manifolds... But they were brand new. Having said that, I have heard ric wood recommends cam coat and a friend has tried it, so very interested to see how it goes. No idea on how it manages heat. They literally were not on that long!

    Not a coatings as such but have you thought about exhaust wrap?
    If your serious about a cooler engine bay exhaust wrap does a good job. Cheap and easy to fit/replace as well.

    Exhaust wrap is a no no for me, caused my pinto manifold to crack and disintegrate, and did the same on a friends 2.8. Not worth it in my opinion!

    You're probably quite right, I could see it being a moisture trap.
    BUT it does do a good job of reducing under bonnet temps. I've got to modify one of my headers(hitting my swaybar), so will be removing the wrap. Will be interesting to see what condition the pipe is in.

    I had a brand new Tony Law mild steel manifold Zircotec treated for one of my rs2000's and it rusted out in less than 4 years with very little track time, but it did cool down quicker after use and you could work on or around it in no time at all. Again I didn't notice any difference with under bonnet heat than a standard manifold.
    It did look nice until is started to rust underneath and flaked off in large thick chunks.

    That's why I had Janspeed make me stainless manifolds for my non turbo 280.

    My manifolds are stainless so rot shouldn't be a problem I've been looking at heats held products in the states they do some good products
