For the last 8 months it has looked like this. Getting my K04's rebuilt took forever. Notice the dented fender.

But there is hope. My engine is starting to look like an engine again. The intake manifold was coated by swain tech. I also installed a set of Vast phenolic spacers. <img src="http://pictureposter.audiworld.com/23081/picture_010.jpg">

I now have a set of K04/K16 hybrids. They were rebuilt by Jacob Buehn, so I do not know if these things are going to work or not. :-/ They do look cool.

They are mounted on a set of ASP exhaust manifolds. UPS lost my stock ones. They also look very cool. <img src="http://pictureposter.audiworld.com/23081/picture_030.jpg">

I lost reverse on my original transmission, so I purchased a replacement. The new tranny actually has more miles, but it does have reverse.

I had my intercoolers and most of my charge air piping coated by swain tech. Sweeet.

Some new ASP engine and tranny mounts to top it all off.

Right now I am just waiting on some fittings for the turbos to come in so I can put it all back together. Hopefully, in a week I can drive it to the body shop to fix that ugly dented fender.

Does Swaintech recommend doing these? This is one piece that is designed to transfer heat, and I'd think coating them would make them less efficient.

So is your radiator, but the factory coats them black.

Yes, sir.

sweet, sucks being without them for long periods.

How does this actually "Pull" heat from the metal? In my mind, paint could only be more efficient at conductive metal-air heat transfer itself if, say, it increased surface contact at the microscopic level.

I'm guessing that most of the heat transfer on intercoolers is via conductive means, wherein air, passing through the surface area of the intercooler, is heated by contact with the metal. If this is the case, I don't know how paint helps that.

That said, as an idea, such coating could also improve radiative heat emission.

Finally, if it had the ability to obviate undesirable thermal qualities of sapphire, it would either need a really strong chemical reducer as part of its formula or require extensive prep (and I don't hear alot of concern about sapphire on uncoated Al in the first place).

Just saying. The aluminum itself has a thermal conductivity "k", as does the air, and the overall heat passed as Watts depends on time, heat differential, and surface area, right? I don't know how sticking another material in between will help without changing surface material.

Not knocking the mod - the painting itself has some value including cosmetics... but the whole "pulling heat" thing sounds, to this reader with a rudimentary knowledge of heat control, like a lightbulb being described as a "dark sucker".

Just saying. Sorry for the length - broken up by many phone calls on this end.

I do know that water (i.e. sweat) works to cool your body more efficiently than dry skin. Would this be considered a heat emitting coating?

I jest of course since we're talking about an evaporative process here and not really a coating.

Trango

Indeed. You're talking about phase change.
