Guagues, Which are most useful? Options

[GTeener]

I already have the /6 dash guagues but not the center console guages (voltmeter & oil temp).

I am not totally sure my oil pressure guague works properly, but I digress...

What I want to know is, would it be be advantageous to have all these guagues (and working of course)?

What are the most important secondary guagues (not Spedo & Tach) for these cars?

Rusty, it is a bit hokey, but that's how thermocouples work, and I can only imagine how much more the gauge would cost if they built in temp compensation. EGT gauges have the same problem, but with temps commly in the 1500dF range, the 40-50dF potential error isn't really significant. (IMG:style_emoticons/default/wink.gif)

Of course, here in the wonderful San Francisco Bay Area, the weather is always the same, and so the gauge always reads consistently. (IMG:style_emoticons/default/biggrin.gif)

Dakota Digital also sells a CHT gauge with temp compensation, for something like $250.

mistro, EGT is exhaust gas temperature. EGTs will change with mixture and ignition timing, just as CHTs will. The curves for EGT v. mixture and CHT v. mixture don't exactly match, so you can determine rich/lean from how the EGT and CHT change with respect to each other.
