Flat blacked the intercooler...
#32
I have heard the same - Anodizing is OK, but off the shelf black-paint is not. I have heard that the radiator specific paint is safe in light coats, but will chip off easily and need several coats. Kind of a catch-22 there. Just my 2 cents!

There is so much more to this then a "1st year Physics class". AS long as you keep the thickness of paint under .003" and make sure to use a radiator paint or some other type of paint with a high Boron Nitrite content you will be fine and on the crappy stock intercooler you will see no difference at all. Now if you use some genero paint like home wood paint then you will see a big difference as you have succesfully insulated your intercooler. I like the look.
Oh yeah and for all the people who think they are engineers and have "heard" that it will affect the cooling, why not take a look at any turbo Ford or turbo Chrysler made from 85-93, all the intercoolers are black. Oh yeah and Garrett themselves painted cores for the better part of 20 years.

How about some real science. Here are a some books that deal with coatings, thermal effeciency, turbines, turbo chargers and heat exchangers (intercoolers). Not very entertaining reading, but informative.
Fundamentals of Thermal-Fluid Sciences, by Y. Cengel and R. Turner - great resource for radiation effeciency, covers paints, aluminium and most everything else
Heat Transfer Essentials: A Textbook, by L. Jiji - good general resource
Handbook of Turbomachinery, Edited by Earl Logan, Jr. and Remenda Roy - not automotive, but helpful
Heat Transfer Enhancement of Heat Exchangers, by S. Kakac, not automotive but great resource for understanding principles of heat transfer.

i've actually read of a product that's made to coat the front of the intercooler to help its efficiency and it comes out looking like black paint. they tested the stuff out and it worked pretty well...cant remember where i read it at though. when i find it again i'll post it. the engineers who made it said that black paint won't help, but won't hurt the intercooler's efficiency either.

here u go I got it done at Swain Tech in NY.
By the Way u have a evo. Theres not point in doing this.
I like the fact that i can roll on the highway get into the left lane and have every car in front of me, just move to the right! LOL its just GREAT

If it's a DIY job, then it is likely that you'll get too thick a coat. And about the maximum thickness of the paint, that entirely depends on the properties of your paint.
In anycase, I think manufacturers paint radiators more for surface protection and looks rather than to aid efficiency.
btw, in my original post, i said the color only affects the radiative properties of the i/c. [which has no significant effect, i think]. I even mentioned that the oil cooler is black.
