What are some useful gauges for a non-turbo motor?

[only5kgt@uswest.net]

Hello audifans,
See question above. I have been playing around with some
ideas for my Coupe dashboard- and I had the idea to add a
few more gauges (complicated story- partly to do with
aesthetics, but I'll get to that later)...
I have a nice VDO vac/boost gauge which matches the dash OK.
Can't remember the series. I know the NA motor doesn't need
the boost side- but, what would be two more dials which VDO
makes in that aux gauge size- that would serve some purpose
on a non-turbo? The '85 CGT has  clock, temp, fuel, tach,
volts, oil temp, and pressure, (and vacuum!) already. I
thought outside temp, so what's one more? Any thoughts?

I have a silly motif I'll share *after* I find out if there
is one more useful dial to add to the really complete
instrumentation. Sorry for the WOB...

Regards,
Rob
