Ok I have a winter project and I need some advice. The shop where I work does Powder Coating for our Furniture... and I was getting some prices for getting some parts done. I want to coat my engine cases (primary cover, and cam cover) I was just wondering ever anyone knew the temperature the cases get to while in operation? |

Not sure of the actual temperature. But I would say make sure the stuff is good for atleast 500 degrees to be safe. The fans come on around 400F or so. but being an air cooled motor every component is basically used to disapate the heat. I doubt anything external would get even close to that. but its better to have some buffer |

i believe black coatings actually help sink heat from the engine. helping keep things a little cooler. |

Yep that's what I learned in my college physics class, a black coating will actually help transfer heat out of the engine. Flat black is better. |

Odie has powder coated his cases gloss black. They look sweet, and he's had no problems I know of. He powdered them himself. Powder coat has to get up to like 350o to flow. I don't think the cases get that hot really. |

You can expect as high as 400 (F) You should contact the shop doing your powder coating. There are many variables to consider BUT you can get most industrial color powdercoat finishes to flow between 350 and 400. The industry is working on other systems which can melt/flow at lower temperatures but that's less common. If you have access to somebody doing powdercoating on wood, you're already dealing with folks doing pretty low temperature powdercoating. If you need temperatures lower than 350, you ought to consider a high quality polyurethane or epoxy. Nearly as durable and room temperature. Some good info at the Powdercoating Industry homepage: http://www.powdercoating.org/home.htm (Message edited by slaughter on September 22, 2007) |

i don't think you will have to worry about temp. i have my cases painted with regular automotive paint. they hold up just fine. so i would think you wouldn't have any problem with any kind of powdercoating. good luck and don't forget to post pics when you are done. |

Powder coating your casings is no problem provided they are cleaned/degreased properly it's what I do so I should know |

The shop doing my powdercoating is where I work. Woodard Furniture. We do Iron/Aluminum/Wicker furniture... obviously we don't coat the wicker.. lol but I know now that the powder has a heat temp of 500 degrees... so seems like it might work |

The only thing with balck being a natural heat sink is that you will feel heat radiating from your motor more than you do now. I had this happen when I had a black ceramic coated header installed on my bike. I definately noticed an increase in ammbient heat around the frame than before when I had a stock non-coated header installed. Having heat pulled away is a good thing - just realize that it has to go somewhere - that somewhere is right near your legs, ball*, and a*s. |

You want to dissipate as much heat from the engine as possible. You want to keep as much heat IN the headers as possible. |
