Looks good Rusty but I think you were a little too conservative with the Bell curve on the ducts. They'll probably work great anyway due to external diffusion helping a lot. Finn has ZERO ducting (basically a box with hole in front) and it works amazingly well (now that he has some decent heat exchangers : )

Well Ed, I hope you're happy :-) Just say it's perfect, and there won't be any trouble :-)
Clearly, I still have some work to do to get these mounted permanently, but I can't do that until I put the cowl back on and find the best alignment with the inlets. Unfortunately, I couldn't do that because I had to add to the inlet lip on part of the cowl, and the epoxy was still wet. I think that's the really downer about dealing with fiberglass. Everything take multiple steps, and you have to wait for glue to dry between them. Anyway, I anticipate some pain and suffering when it comes time to get a good transition between the cowl inlet, and the ducts, but so far, I'm quite pleased with how they're coming along.
Unfortunately, I have to go back to work (such as it is) for the next week and a half. After that, I should have plenty of time, because Philips is still planning to lay me off. Amazingly, they're already talking about hiring me as a consultant until they get an official slot opened to hire me back.
Cheers,
Phil-bert (Philips-Dilbert)
