I posted this article on the 6.5 forum. Its directed to gas engines, but has some pretty good info on turbos & superchargers.discuss potential benefits vs detriments-
I think it would be good providing low rpm boost, and have it "hand-off" at a higher RPM that a larger turbo could then take over. A clutch to disengage around 1800rpm or something.

Would be cool no matter what, just because. And since you live 10 minutes from me, giddy up!
I think what you are getting to is a Turbo-Compound Engine As the article says, at some point the turbine is making as much power as the crank.
There are much better ways to turn a turbine than using a pistons and a crankshaft to generate heat. If you want some REAL HP you need to get rid of the recip engine and just leave the turbine. Airplane engineers realized this years ago. There have been running automotive turbine cars, Chrysler tried it, Rover did as well. You want to show up those wimpy Duramax guys with their 5" exhaust pipes? Show 'em a REAL exhaust pipe, something like 10" or so - then stick on an afterburner and truly show them who is boss!
the problem with that is the turbine sucks down too much fuel to be practical for a daily driver, its a cool concept though.
Probably tough to get stuck when you have propulsion! How does reverse work?
VW does just this, they call it "Twincharging". With a direct injected gas engine, the results are impressive. I thought the supercharger uncoupled, but I don't see that now. Perhaps, as the turbo comes up to speed, the supercharger just "free wheels"?

Who's talking about fuel economy? We're talking POWER!
Yea I was having a bit of fun here. Excessive fuel use was one of the big problems with turbines. I did see one of the Chrysler turbines once at a car show. The Amelia Island Concours, which is held on a very swank golf course. The guy started it up while I was there. Real quiet - and it burned a spot of the putting green from the exhaust!
