Is the prcedure the same as powdercoating any other part?
and is there any concern with heat dissapation?

Generally not a good idea and it's best not to coat the rotor housings. There are different types of commercial powder coating processes and some powder coats are formulated to improve heat dissipation. Most powder coats are thick and act as insulators, but there are also commercial processes where the coating is thin and has special heat conduction properties. Thoroughly cleaning your housings and applying a thin layer of paint can give you a great appearance for a long time with little effect on heat dissipation. Opinions will vary on this one.

can the heat of the oven affect the housings?

No, powder coating only uses about 350F.

YES i lost a housing in the oven on a powder that needed to cure at 400 it went into the oven twice and worped it. trust me do this at your own risk. the plates will do good with no problems tho.

oh ok. thanks. how do so many people powder coat their engines if it suffocates the motor? do they just use a thin coat or what?

most people just use a high temp paint, but if you have money some people ceramic coat them.

i want it to look really nice. spray painting can turn out fairly tacky. if powdercoating is bad for the motor than are there any other methods? can ceramic coating be done in colors?

Ceramic coating will act as an insulator, it retains heat (which is why people use it on exhaust manifolds/turbine housings)

Ceramic CAN act as an insulator, BUT they also make ceramic coating designed to dissapate(sp?) heat. In fact there is a company (link somewhere on this forum) that does both housings, and irons in cermit. Very pricey though. Personally I don't think that the insullating factor of powder coating would be all that big of a deal, after all we do still have water and oil going through our engines. You would have to use a high temp coating though. The high temp powder i use on my LIM is good up to 1000f with 1200f peak. It does require a higher cure temp. 400f for 20mins.

Here is a ceramic coater in our neck of the woods.

JHB's Cermet is for the inside of the rotor housings to promote less friction, better oil retention, longevity, etc. etc. Unless there was a link in there that I missed about them offering a coating for the exterior of the housing. Again, I don't think any kind of ceramic/Cermet mix will really help heat transfer from the rotor housing to the engine bay. Although, if your cooling system works properly, you may not need it.

I coulda swore they sold, new housings that had been coated outside as well. Oh well, the mind is the first to go.
