  I own a 1963 Studebaker Avanti with the R2 supercharged engine.  I got
the idea of putting a clutch on my blower after seeing it done in the
the Australian film 'Mad Max'.  The reason I wanted to was to improve
my gas milage during normal driving while still being able to blow the
doors off of almost anything on the road.  Wrong.  After talking to
some people who know a good deal about supercharged Stude's and by
experimenting with my own car I found that disconnecting the blower
is not a good idea.  The carb(s) on a supercharged engine is jetted
for the compressed air.  If the blower is taken out of the system,
the carb dumps in more gas than can be mixed with the small amount
air coming in.  It makes the engine run much less efficiently and
get worse milage than with a good blower on.

  I was also thinking of being able to switch from the normal
supercharger drive pulley to a smaller one.  The smaller one would
make the blower spin faster and therefore produce more boost.
This would cause the same type of problem but to a lesser extent,
but the reason I didn't try it was because of the problems of
coming up with a good device to switch between pulleys on the fly.

  I am a big fan of superchargers and would like to see them on more
new cars.  Unlike their little brother, the turbocharger, they help
the engine run even cooler than normal.  They are also a good means
of increasing power while still keeping a low compression ratio.  My
Avanti can kill anything made today (Except maybe the 930 & Countach)
in the quarter mile and can run on regular gas as well!

                      Studebaker still lives!!!
