Back engine scoop
 

Does anybody knows what would it take to replace the scoop of a 336, for one for the 337. I know it looks like lots of work, I wonder how it would improve the aerodinamics.
Ha anyone done it?

Francisco, the larger air scoop was to aid cooling, when they did away with the engine mounted fan on the 336. I suspect it would add more drag, not to mention change the cooling of the rear engine. I don't know enough to say that would be good or bad.

It would be a major undertaking.
