Cool, that W16 looks awesome.
Some tech school teacher built a W9 with 3 banks of 3 cylinders at 0-60-120 bank angles.
It was a beautiful design.

Nifty! Pity they didn't show the crankshaft.

A guy called Thomas Johansen built a superb W9.
There is a PDF describing it in detail, (a summary of his thesis).
The whole package is so neat! 3 big ends per journal, 4 main bearings.
Short, light, it's awsome.
The Motors Negre was a cool idea, but i think the rotary valve maybe let it down a bit.
I tend to believe rotary valves and rotary throttles create heaps of turbulence on the intake killing power.

Hey dynosor, good research!

Life F1, the motor did not have a very good run and was dropped for a DFR or a Hart, I think. Looks a lot like the MGN w12 except for the rotary valve, little information is available.

All alone in a hijacked thread nobody reads, I found a small snip of information with reference to an X11?!? X11? Does anybody know anything about this X11?
I think it was an Auto Union project that Porsche may have worked on.
