In reply to a post by Carter Shore Easy, all you need is a louver cutting machine ... winking smiley

Ah! I'll run down to Autozone and pick one up!

I've also thought about Le Mans vents some day.

In reply to a post by Bradley Cogan If you want to reduce the under bonnet temperatures you could just get louvres cut into the bonnet like a GT6. It would allow the hot high pressure air under the bonnet out and improve the airflow through the grill, radiator and engine bay.

I have considered that in the past...how does one, "get louvres cut"?

Who or where to you go for that? Is there a tool?

Garrett,
Hook up with the local "Lead Sled" hot rod guys someone will either do louvers, or they will know where to get them done.
BTW louvers aren't particularly good at letting air through. an equal area hole works much better. So the "LeMans" vents aren't a bad idea.
All the best,
Paul

I had a set of headers made for my 1957 TR-3 about two years ago, and had them ceramic coated. I did test fit them before coating. They work and look great today! Have attached a pic of what they looked like before they were coated.

Sent the headers out today for the Classic Polish look at Jet-Hot. I know some think they are too expensive...but same price as I could find anywhere local to me...

Plus they warranty them for life and will redo if ever a problem.

Website says "lower surrounding temperature by up to 65%". Again, same questions as already asked in this thread such as 65% of what? From what starting point?

Hi All,
Sorry to be so late entering into this topic. Happens at my age.

I have an article from a Rod & Custom magazine dated 2010 where temperatures of plain, coated and wrapped headers and runners (pipes from header flange to collector) on a V-8 were measured. I won't give the wrapped temps as that has not been recommended for everyday use due to trapping moisture, although there may be new technology out there. I'll quote one bank of the V-8. One of those temperature guns was used.

Plain Ceramic coated
Header flange 234.8 195.3
Header runners 200.1 128.8
Header collector 233.4 185.6

Pretty decent temp drops from my perspective. I plan to have my manifold and down twin down pipes for my engine swap ceramic coated (my build is in the Build Journals as SpitWagen ).

Cheers,
Richard

Thank you Richard!

In that case it looks like the drops were respectively as follows:

Flange - 17%
Runners - 36%
Collector - 20.5%

It isn't "65%" but I agree still significant. I have not received mine back yet, another week I guess.

Garrett,
Well that is one way of looking at it, but the people who quote 65% could just as easily say 17+36+20.5=73.5% we have exceeded the claim!spinning smiley sticking its tongue out
All the best,
Paul

I think there are so many variables related to under hood temps that the ceramic coating specialists can say most anything they want. Will ceramic help? yes! How much? Some! If you want pretty headers, coat them. If you want less expense, wrap them. Either way, more airflow will also help. Sections of preformed Louvers are available.
This is one option. http://www.ebay.com/bhp/hood-louvers

This is probably over the heads of most of us, but is a louver option.

Beautiful. Mind if I ask you how much? I want to do this too.

Rich,

Not at all...$250 plus guaranteed for life.

I'm happy.

I am late to the thread, as the ceramic coating has already been done, good on you.

I have a local shop do titanium ceramic coating on the exhaust systems I use on my motorcycles. Ugly grey/green colour, but the highest temp reduction. I also have the exhaust valves and the combustion chambers and the exhaust ports ceramic coated when I build the motorcycle engines. Temperature reduction of the outside of the pipe, and in a Spitfire engine bay, is an acceptable side effect, but not why I do it.

The point of the exercise is to increase the exhaust flow speed for better exhaust scavenging. The better the scavenging the more fuel you can burn effectively and the more power you can make from the engine.

When you ceramic coat the exhaust pipes, and especially if you also ceramic coat the combustion chamber and exhaust valves and exhaust ports in the head, the exhaust gases retain more of the heat and take more of the heat with the gases as the gases exit the engine. With the better exhaust scavenging, the engine starts to run leaner. On a carbureted motor you will actually have to richen the carb jetting to compensate. More power.

I am aware of the conventional wisdom that says you do not use exhaust tape wrap on a street vehicle, retains moisture, wrecks the exhaust, etc. I use exhaust heat tape wrap over top of ceramic coated exhaust pipes all the time, have been doing so for a number of years, and have not experienced any issues. When it gets wet, just continue to run the motor until the moisture steams off, which it does quickly. This is the exhaust wrap I use https://www.ptpturboblankets.com/products/ptp-lava-exhaust-wrap It also hides the ugly gray/green of the titanium ceramic coat!

A couple of years ago I built a motor for an air cooled 1979 Honda CBX six cylinder motorcycle to be turbo charged. I had the combustion chambers and exhaust ports of the head ceramic coated. I used an older used plain bearing Rajay 310 series turbo charger, took it apart to rebuild it, and had the turbo charger castings ceramic coated. Then I had the exhaust system I built and the waste gate ceramic coated. Then I exhaust heat tape wrapped the entire exhaust, and used a PTP turbo blanket to encase the turbo, which sits only a few inches from my crotch when I sit on the bike to ride the bike. I have now ridden the completed bike a couple of thousand miles, no heat related issues at all, the exhaust heat tape is holding up well, the PTP turbo blanket around the turbo is holding up well, and the exhaust heat tape has easily survived the bike having been unintentionally ridden in the rain several times.

As you can probably tell, I am a big fan of ceramic coating of exhausts, headers, combustion chambers and exhaust ports, etc, as well as exhaust heat tape wrapping, Cheap additional power with the added benefit of reducing external heat. I can actually touch the exhaust pipe off the turbo with my bare hands when the bike is fully up to temperature, good thing as the pipe pretty much touches my leg for lack of available space and the otherwise very hot turbo, encased in the turbo blanket, is very close to the parts of my crotch I am very fond of and do not want cooked......
