Steve Rankin TC 6646 hi Steve - which one do you mean? The inlet is usually block colour, whereas the exhaust was originally aluminized, i.e. metal-sprayed to prevent rusting. However, black would be better at dissipating heat, and this is what I used on my Derrington extractor manifold made by "Mike the Pipe". oc[b]T[/b]agonally Roger TC0978 TC2365 PS here is a reply from 30 Sep 2000 on the subject: I had mine coated with aluminum by: Custom Aluminum Coating and Metalizing 9030 Emnora Lane, Houston, TX 77080 (713) 465-7114 Mine was done in 1991 and still looks excellent (granted I don't have a lot of mileage on the car but even sitting around and being taken on and off they get a bit beat up). They give a lifetime guarantee that the coating won't chip, crack, or peel. And say that if you really mess them up they'll redo them for $10. It only cost $90 but of course, my last contact with them was in 1991 so prices might have changed since then. Gene Gillam Saucier, MS 39574 1949 MG TC 7872 [/quote]

Re: [mg-tabc] manifold color

The actual color of your manifold will make not a whit of difference in dissipating heat however, a coating containing actual aluminum particles may be slightly superior as aluminum is a pretty good heat conductor. Paint in any color may act as an insulation. My personal preference has always been a particular shade of lavender blue poly with a very high metallic content for heat dissipation which I think was original on certain cars.

Re: [mg-tabc] manifold color I assume you chose the shade to pick out one element of the carpeting in your TC!

O'gosh, here we go again. In the interests of economy whilst putting my 1500cc motor together I had my exhaust manifold sand blasted and then nickle plated. It only cost $10.00. It still looks great even after 3 years use,(It turned blue around the hottest parts) but is partially hidden by my Datsun Steering box. Ron --- Ray spook01@home.com> wrote:

Re: [mg-tabc] manifold color Pete. What you are thinking of in your sunlight test is the ability of a darker color to ABSORB heat in the form of sunlight as opposed to the ability to DISSIPATE heat. I respectfully submit that if you were to take those same two similar objects, one white and the other black, heat them to the same temperature, place them side by side in the dark, you will find that they will cool at precisely the same rate. Car radiators are painted to protect against corrosion. They are black arbitrarily. They would function just as well in any other color, home heating radiators which perform the same function are traditionally painted silver. If car radiators are painted properly, a special non-insulating paint is used which, I believe, is available only in black. Generally, racing cars which need every bit of cooling ability they can get have their radiators left unpainted. A radiator with a polished header tank will have slightly less cooling ability than an unpolished one due to the fact that the polished surface will have less surface area to dissipate the heat.

But when you get to real physical thermodynamic principles, I feel compelled to set the record straight. Your comment that color will not make a "whit of difference" is simply scientifically not true. I invite you to take two objects of the same material and paint one white and one black. Start them at the same temperature and place them in bright sunshine. After some period of time, remeasure the temperature of each and you will find the black one to be warmer. This demonstrates the property of emissivity, the ability to transfer heat. How many fancy show cars with their lovely polished brass radiator tanks have you seen that are chronic over heaters?? It may have been the technological dark ages and they may not have understood the reason, but those early engineers knew enough to paint radiators flat black. They found it worked better. I have had my exhaust manifold finished in an aluminum plasma spray. It comes out with a rough white finish. It looks very much like the original (as best I can recall - at my advancing age, memory is suspect). Most any stains burn off cleanly. The only draw back I have noticed, is that if rubbed with a hard object, the flat white finish can become polished and appear aluminum silver.
