Random question relating to the previous heat transfer off topic debate:
You have a standard 14ga copper wire carrying a couple amps of current. Basically the wire is hot. Will the wire be cooler if it is bare copper or will it be cooler if it has plastic insulation over it like a regular house wire?

The wire with insulation is actually cooler. This is because the although the conduction heat transfer resistance increases a little the convection heat transfer resistance decreases quite a bit due to the increase in surface area. It comes down to something called the critical radius. If you add insulation while you are below the critical radius it will increase heat transfer. If you are above the critical radius and add insulation it will decrease heat transfer. Just random bullshit from my heat transfer class this semester.
Anyways...there are three types of heat transfer, convection, conduction, and radiation. When you paint the manifold black you are very slightly increasing the conduction heat transfer resistance. The convection heat transfer resistance pretty much stays the same and the radiation heat transfer resistance will increase.
Assuming the manifold is at a higher temperature than its surroundings(i think that is a fair assumption) the radiation heat transfer will increase because it will more closely act as a blackbody. I doubt the temperature difference is very big so i doubt the difference in heat transfer is really going to matter.

"geezes ----, how will that turbo fit in there?" says my manifold fabricator. lol
got the motor installed as mockup for my 3" IC piping, 4" exhaust & custom twin scroll dual 38mm WG manifold
car looks good, need to ------- repaint my intake mani though, got all fucked up and the paint got runs in it. so when i have time i will take it off and sandblast & repaint.
Pics to come ------ bought a shitload more stuff for it
put on my aeromotive FPR on my BDL bronze fuel rail, ------- mad tyte.

I wanted him to tell you That I'd fight you but I think he was scared :1

some wheel bearings and a bunch of other maintenance ---- for Rachels car, and i need a black -8AN in/out fuel filter. 
PS. I updated my photobucket but dont have time to post them. Need to get to my cushy student summer job.
someone put up a couple
