" I agree, without the special gearbox it's uselessly high rpm.

even with it, it's pretty useless.  -power- throttles well, but -rpm-
does not.  the one street car i heard of with a turboprop in it had
an automatic trans and was driven more with the brake than the
throttle.  iirc it 'idled' at almost 60 mph.

now if you replace the alternator with a hydrostatic transmission...
