I am considering fabricating a carbon-fiber oil pan for my 20b in

order

to save a few pounds, but I'm concerned about the temperature range of
carbon-fiber.  Is there enough temp. safety margin, or would aluminum be

a

better choice?  I've read about carbon gearboxes on race cars, but the

temps

may be much lower than in rotaries. 

I'd think for high temp applications you'd be better off with s-glass than
carbon.  High strength and good high temp capability.  Although I'd guess
you will find little, if any, weight advantage over aluminum.  My custom
aluminum pan for 20B weighs only 4.5 lbs.  Nice thing about a glass pan is
that will be translucent enough so you can look at it and see your oil
level.
