From my learnings through H-t and speaking Goeff and all them, painting will not hurt performance at all. When i painted mine, i didnt not have any problems what so ever. I think of the IC as a heat sink in your computer. Most heat sinks have fans built in. But in the car your fan is the air you build up when your car is moving. So with that said, if you are not moving and air is not moving through the IC, it would not even matter if the IC was painted or not. Just like the radiator in your car...they come painted. why would car builders spend extra money painting or anodizing the radiator? effeciancy will really depend on the structure of the IC and outside temps air. So take that how ever you want to. Like i said, i never had a problem with mine black and neither has anyone on this board that i've talk to who painted theirs also.

 

There are a ton of factory intercoolers that come back. All toyotas intercoolers comem black. Is this painted or anodized black? Same question goes for radiators that are out there. I dont' think the paint will do anything. The paint will add almost nothing on the surface of the fins. Painting the ic won't penetrate the fins inside or even teh fins internal in teh core. Paint on the endtanks won't do anything either since endtanks do nothing for cooling purposes.

my fmic is yellow!!! i have a black car and i want every1 to see it. does that mean im rice now?

 

Use this:

"Radiator Black" paint from Eastwood
$9/can

im from walnut creek ive never seen ur car , we need to race....

 

im actually in college now, UCSB Santa Barbara...

Not sure if this was directed to me?

I'm not much into racing, other than the occasional impromptu street race.
What are you running (mods/ 1/4 mile)? IM if you wanna talk. thanks

 

so was it the CHP down south that made you take off the turbo?

 

my friend has a grill thats shaped sort of like this (cross section)

i forget what it's made out of but it really doesnt block the air at all and the only way you can see the intercooler is if you lie down on the ground right in front of the bumper and look up through the slots

no it wasnt directed twards u it was to the thread starter , but ill run u if u want

 

Anodizing adds a thin layer of alumina to the surface of the material. The thermal conductivity of this oxide is less than aluminum…but it is a very thin layer that is applied.

(average properties)
Aluminum thermal conductivity
K=153 W/m°K

Alumina Oxide thermal conductivity
K=18 W/m°K

Obviously not the best choice for heat transfer. However, the alumina oxide does increase active surface area of the anodized surface. This is due to the porosity of the thin layer added. This additional area gives the FMIC a boost in emissivity in the infrared range and possibly greater heat transfer through convection.

(average properties)
Aluminum emissivity
0.12

Anodized Al emissivity
0.85

As you can see, there is a compromise when you anodize AL. I plan on data logging the air temps of my FMIC pre anodizing and post anodizing to figure out the effects of anodizing……I just have to get my autronic up and running
