Hey Gang,

Being from the old school and I do mean old!..

Paul the problem with audio. The FAA requires us to
have one oil pressure direct reading instrument for
each engine installed, same for temp, tach and gas
gauge etc: and on and on.

I like to see as well as hear. Heck one of my two
senses could just quit anytime!..ouch  but both visual
and audio together would be fantastic. I like a
cluttered panel it makes my walter mitty come out. (I
drive a varieze). Now if someone would come up with a
"heads up display" at a reasonable price!!..hummm how
bout a back lighted LCD laid on it's back with a
polished piece of plexi set at a angle for a
reflector?..

Does that FAA rule apply to experimental airplanes?

Yes it does.  That's part of Part 91 (91.205), so it applies to anyone flying under Part 91 rules (which is us).  In addition to oil pressure, you would need the following instruments for a rotary:

       1.  Tachometer;
       2.  Coolant temperature gauge;
       3.  Manifold pressure gauge (if you are turbo'd); and
       4.  Fuel gauge.

Them's the rules.

Got my $15 manifold pressure gage right here (for normally aspirated). 
Just subtract the outer numbers from 30. Or redraw the scale.
