Leawood911:
But Mike sounds like he is on the correct track. Some type of hybrid Turbo
Maybe an electric super/turbo-charger unit whose output plumbing is merged with and supplements the exhaust-driven turbos? Keeps the exhaust heat from conducting into the electric stuff?
I still like the idea of electric spool-up assist via common impeller/compressor/electric-motor shaft, but recognize that shaft conduction of exhaust heat is a problem that might take exotic remedies.
