Time to paint the intercooler heat exchanger black!
Really surprised how big a difference black paint could make!

i dont know???
that test is just with "air" going thru it, i dont think we can just assume it will be the same temp difference with fluid going thru??? may have to do another test and see that result.... what you guys think??

Funny how drag racers, who look for every single hp, don't paint them, as well as the factories.
Now, if we all ran our cars with a hairdryer on a workbench, then we are talking!

This totally makes sense, but only for night driving. If you paint it black, the heat can't see the intercooler, and it just passes by.

I did flat black 5 years ago, as I liked the stealth look but no temp change. Imagine that

The improvement only matters if there's very little or no air going through the heat exchanger (such as when idling still). The only limitation in these guys testing methodology, is they used a hairdryer on the highest setting which put out air hot enough to boil water. Testing it with lower intake temperatures (more realistic to what intercoolers will see) would show more real world results.
But with that said, now you know why engine radiators are commonly black from the factory :-)

I had a debate going with a buddy about this and I told him the test was far from real world as IAT's at idle are going to be barely above ambient as there is nearly no compressed/heated air going through the cooler. Not to mention an intercooler or HE sitting on a table isnt the same as on a running car in front of a hot radiator and engine.
Bottom line is if you want to paint it black..fire away but it isnt going to make it better or worse.
