tolerances and better designed/CAM blades and compressor housings.  The ball
bearing thing, altho once thought to be the *next* big breakthru hasn't
really manifested itself in practice...  Yet.  I believe this to be related
to the testing issues where most ball bearing turbos were tested in
conjuction with other variables (lightening of wheels the biggest).

Jimmy - You might want to see if you can beg, borrow, steal or, failing
that, actually buy a copy of Corky Bell's recently released book
"Supercharging"

He's redone & greatly expanded on the chapter on intercooling originally in
Maximum Boost.  BTW, on another food for thought matter, if you carefully
examine some of the B&P IC designs vs. say the extruded tube construction,
you may see that the B&P's have significantly more flat vertical faces.
It's been suggested, especially on the intake side, the addition of a rolled
face, or "teepee" might improve air flow, i.e.
the face would look like:
