engine bay paint question
 

I was wondering if spraying my engine bay black would suck a little heat from the engine.
or if it would keep more heat in the engine bay.
I guess this is more of a theoretical question.
just wanted to know what every one thinks.

I think Boo Radley fucked you in the ass Atticus.

Probably wouldnt make to much of a difference considering it is a pretty top sealed inviroment, plus the radiator is there for a purpose.

hey DMC1 I think you should stop sucking your boy friends cock for long enough to catch a breath.
like I sead this is a theoretical question and I thought you guys might have something interesting to say.
but when I get the response I think Boo Radley fucked you in the ass it shows me one thing.
YOU ARE A FUCKEN MORON !
yes I know most likely it wont do any thing and yes I know what the rad is for.
thats why this was a theoretical question.
black absorbs heat so technically it should suck some heat out of the engine (not a noticeable amount)
but then if the engine bay gets hotter wouldnt it keep more heat in it, there for making the engine run a little hotter (again not a noticeable amount)

so unless you got something interesting to say shut your trap.

I'm pretty sure that the colour black vs temperature is only affected by UV light. Otherwise the popular colour for laptops would be white, not black.

Yeah I agree *L* black absorbs the most amount of light of any color. if your a cold blooded reptile sitting on your favorite rock trying to warm yourself in the moring sun it's a real good idea to be a blck to dark brown color.

the color black itself won't really affect anything in the engine bay. black just doesn't reflect as much light away from itself as other colors.

When you close the hood your engine bay is dark unless your hood light stays on and that kind of like the light in the refrigorator question. noone knows the answer to that.

if you want to get all theoretical make up some real sweat heat sinks and attach them to your block and head then make up some type of ram air duct work and run it over the heatsinks. Have you ever seen some of those all motor v8 dyno competitions? those guy put a big old heat sink between their carb and the head.

so on an import you could put one between the throttle body and the intake manifold or between the intake manifold and the head.

or between your pink dildo and your ass, stop naming yourself after closet fags in old moveis. / emo fag bands

hahahahahaha, now i dont feel so gay for reading that book in highschool.

having black paint next to a warm object isn't going to suck the heat in. Although black paint tends to absorb heat, it has no heat vaccume effect. That object (the engine) has to radiate the heat, through diffusion of thermal energy. Heat, on its own, is always going to diffuse and create an equilibrium unless more energy is being put into the system (which in a car, it is). All you would be doing by painting your engine bay black, would be slowing down the transfer of thermal radiation through your hood/bay. Creating a heat trap inside the engine bay, the thermal radiation is going to diffuse, but now at a much slower rate.

Basicly, you could just picture putting coffee in a styrofoam cup, do you think this would keep it cooler than being in a paper cup?
