So I painted my engine bay black and want to paint my engine and tranny black too. Does anybody have any pics or are there any disadvantagous of chosing that color?

 

I humored myself with a quick google search and it looks like you are a trend setter. Cheers to you for breaking new ground with a rattle can.

 

too much of one color, and not enough contrast, but its your car mang

 

when i joined H-T a couple years ago i would wonder why everyone on here was an *** hole to people asking simple questions, but today... today i understand why...

hmmmmmm only two disadvantages come to mind w black paint (and any paint for this first one) if you use the wrong color or don't steam clean the engine first the paint will look like crap when it starts peeling, but more importantly how can you tell where oil is leaking from if it's blending in w the paint? just my thoughts.

 

Do everything black. and leave your valve cover yellow.

 

I had a buddy whose car was silver, and did the engine bay black, trans black, and block black. Things to concentrate on were powdercoated silver, to really attract the eye. It was nice, but it's gotta be done right otherwise it just looks like a rattlecan job.

 

right there with you haha

 

You are learning the ways of those who breath with out a half open mouth.

 

disadvantages:

black absorbs heat very easily and it is very hard to dissipate heat through such a dark color

 

You are wrong. It has been discussed many times what the color black does heat wise... I took this from a quick google search, do what you like with it and decide for yourself, but just think how many radiators come black.

"Fact? It's been said that black is actually the best color for dissipating heat from the engine. This statement is true, here's why:

The reason black paint dissipates heat more than any other color is that black is the most capably dissipative color for infra-red (heat) wavelengths. As we all know, back is very absorbent when energy rays (visible AND invisible) such as sunlight hit it. It is also able to cast off the most heat energy, all of its radiation being in the infra-red part of the energy wavelength spectrum. Single colors tend to focus their ability to both absorb AND dissipate in the wavelength of their color, and far less in the infra-red compared to black. One last thing about black: It absorbs energy better than it dissipates it, which is likely why the effect of black dissipating heat is less known. Also, since it absorbs far better than it dissipates (as do all colors), it has a net gain, for example when your black car sits in the sun, until an equilibrium is reached depending on the heated body's ability to be cooled (like with a fender or hood, by the surrounding air). The ambient temperature of the air around the black fender keeps it from heating beyond a certain range. I hope this helps explain the "I don't know why" of black paint being a better cooler for engines. The effect won't be much, and might not even be noticeable unless closely monitored, but it is a fact.

Black radiates heat in the infra-red spectrum better than other colors, which tend to "specialize" by radiating less efficiently in the infra-red and more in just their color portion of the spectrum.

Speakers analogy: With regard to black being able to radiate heat well, heat is like a bass note, black is a woofer, and other colors are "mere" tweeters. "
