Turbocompounding

[Robert Humphris]

41.1 Liters? and only 4500 hp thats not much over the 100bhp per liter
that any good race engine can produce.  But this was in the 50's so we
should give them some credit I suppose.

The only way to prove this is to make a working version of this
ourselves, anyone want to join in a new project? hehehe
