This is what annoys me about mighty car mods, a lot of what they "prove" is actually bullshit, but they do something that looks like science therefore 99% of people watching will believe it wholeheartedly.
"With airflow the difference is negligible". This is the sentence, taken directly from their mouths, which anyone genuinely interested in the science and/or potential application for their own projects should be looking at. What is an intercooler, is it an item that uses radiation alone to conduct heat out of the intake charge? No, it relies on airflow to work as designed, so why the f*ck are they testing the radiative capabilities without airflow at all?? The results speak for themselves - when tested with airflow the intercooler's efficiency decreased marginally when painted.
You want some real science, here's some nice basic facts that should explain everything you need to know about this:
Aluminium = good conductor
Paint = poor conductor
The purpose of an intercooler is to conduct heat out of the intake charge into the ambient air passing through the intercooler. You should be able to work the rest out for yourselves.
