Title: Black intercooler?
Post by: Apearcey on May 09, 2017, 12:49:13 pm
I'm assuming the majority of people have seen the video by Mighty Car Mods myth busting intercoolers. They found that black intercoolers actually pump out FAR colder air.
Colder air = performance, but does anyone else have any proof of this working? Has anyone gone from a chrome/silver intercooler to a black one of a similar spec and noticed any difference?

I'm just curious :) I'm considering multiple different mods to my GTI.

not worth the hassle, you wont notice any difference.
you can spray it black for stealth but doubt it would be noticeable

You can also see the video from Engineering Explained explaining that the black paint would only decrease the heat transfer from the air:metal:air interface. So no sure how that black painted IC would work better... :thinking:

Hmm! Curious as to my MCM got colder results from a black intercooler. They never actually strapped the intercoolers to a car, only bench testing with a fan and some thermometers...

Exactly.  I like MCM (well, Moog is annoying sometimes) but that is a flawed test.   As above, Engineering Explained's video goes into a lot more detail.  Just prepare yourself for complex math if you haven't seen it yet!

My own thoughts on it are; if you can barely notice the difference of a bigger intercooler on the bum dyno, then painting one black is going to be completely undetectable, but it might show up as a degree or 3 more on the dyno IATs......whoopee do, the engine won't go into thermal shock and turn to dust, so don't worry about it.
