    i plan on degreasing and painting my engine head (entire cylinder) i was just wondering if black high temp paint will prevent the engine from cooling as easily. maybe it will act in an insulation effect.

    i would like to know because i dont wana have the engine sieze just because i want the engine to look cool.

    I read somewhere (can't remember if it was here)
    someone gave a very logical explanation of why painting it black would help in the cooling process

    does anybody else remember this topic ?

    naa, i dont remember. might be before i joined. but how would it help?? black conducts heat. well, ill look into it on the web. it would be helpful for some input from anyone.

  4. I follow a lot of diesel truck hot rodding and I believe BD makes an aluminum pan for the transmission (automatic) that is powder coated black yet supposedly transfers heat better than raw aluminum....I wonder if the black powder coating is different than black paint or would anything black help
    rid heat faster than raw aluminum....I think a positive result of painting the engine black would be that it absorbs heat from the sunlight and keeps the engine warm to reduce warm up times and maybe minutely decrease the wear and tear associated with a cold start of an engine?

    Okay, I'll step up to the plate, the blind batter:

    typing in paint+engine+black yeilds 19 results, 3 look hopeful

    This topic has an MB.answer, enough folks can chime in:

    A. it Improves performance


    B. it Does no harm


    C. Could be expanded to "designer colored ceramic coatings"? :?

    It is a topic which could have a (label edit) and then be carried to the next insane level of "sky blue works too" and "GIJoecamouflaged paint jobs".

    i was thinkin that it would be nice to paint the motor black and shave the ends of the fins so that theyre flat and then chrome the ends :mrgreen: . like a harley davidson engine.

    it will be cool.! METAL!!!!

    I didn't do the work
    that engine used to be in ebonita (the bike ibeenjammin bought from motokruiser)
    I think the guy who bought the engine still shows up here once in a while (nogoodnic)
    the side covers were polished with a lot of elbow grease and then sprayed with hi-heat clear
    that's all the info I can give...I kept the pics to inspire me when I get around to trying it

    Please keep us posted. I am thinking of doing the same thing on my 70cc. Loco, who did the powder coat on your motor? I was told that you can get powder coat paint in a spraycan at pep boys. This may sound like a stupid question, but isn't a powder coat baked on? I am a little confused. I was thinking of using a hight temp black paint and calling it a day.

    I went to Pep Boys and picked up some low gloss black high temp paint with "ceramic" it suposedly helps to disperse heat more effectively. I also picked up a can of clear high temp paint because I just polished the three covers on the motor and will hit those up with the clear to help resist those monkey paw prints all over my motor. I will post picks when I get a chance.

    i did it!

    hey i did it this weekend, it looks great, i degreased it with that deadly degreaser stuffez...:D then i painted the engine head and shaved the ends:D
    the paint looks really good, its now glossy is more of a flat powdercoat texture.

    i would post some pictures but i still cant figure out how to get pics on here, this new software is confusing!!!:confused::confused::mad:

    can someone tell me how to, the other way was simpler.

    I conducted heat tests on both the Whizzer WC-1 and NE motors. Painting the cylinder with black engine enamel [Dupli-Color #DE1613] reduced the operating temperature by an average of 65 degrees on the WC-1 and 55 degrees on the NE motors. I usually "bake" the paint in an oven for 1 hour at 300 degrees to avoid the curing smell during motor break-in. Before I started offering ported Whizzer cylinders, I conducted research on the internet only to find everyone had different ideas concerning painted cylinders. After a brief trip down memory lane, I suddently realized almost all the cylinders were painted black on all my race motorcycles [1960 to 1980]. I thought maybe the factories might know more about heat contol than I did, so I conducted tests on the Whizzer motor to convince myself of the need to paint the cylinders. Because of my personal test results I won't sell any modified cylinders unless they are painted with black heat paint.
