I'm sorry if this is a dumb question, but would this be considered a
supercharger, since it's being driven by the engine all of the time?  Are
there supercharger or turbocharger impellers that would be large enough?
And finally, would a laser-glue thingamabob (I CANNOT think of the name for
the laserjet like parts 'printers') be able to make a part to withstand the
stress?  If not on its own, could it be used to make a mold or to be coated
with something stronger?
