Thanks for the info! :) Is there another supercharger methodology which
might be cheaper than a centrifugal, and easier to install than a roots?

Couldn't the intake to the roots be re-routed somehow to blow the
air into the same place that the centrifugal would? Or does a roots
run off the camshaft or something, as opposed to the belt? (Or is my
lack of supercharger knowledge showing through again?) ;)

What I always thought would be cool was a turbo or supercharger that
could be turned off. A little switch in the cab would make it free-wheel,
and not generate any power. Flip the switch on, the impeller starts back
up, and you're in business! Still expensive, obviously, but you've got
the "only there when you want it"ness of nitrous, and you don't have to
keep refilling those bottles... If such a switch were a relatively cheap
add on, I'd buy one. :)
