Lucky junkyard find - in a SAAB of all things!

VDO gauges

Volts: much better than Volvo OEM because it actually has markings!

PSI: 0-150. Can't imagine what this was used for because 150psi seems like a LOT for oil pressure, unless SAABS are goofy. (no flamewar, please) 150psi is like 10bar. Stock Volvo is only 5 bar. Can/should I use this for oil anyway?

Continental Imports website shows a couple of possibilities for senders:

0-150 PSI M10x1K 7.0 PSI 30/9 360-023

0-150 PSI M12x1.5K 7.0 PSI 30/22 360-024

One of these is presumably correct for B21/23. Which is it?

So, are you saying that these will fit into the Volvo instrument cluster? Or how are you going to mount them?

The gauges are destined for my '84 245DL. I have converted from the big clock to the big tach/small clock from the GL line.

Below the clock, I have the voltmeter from a Turbo. This will be replaced by the VDO voltmeter. Since my radio is high-mount and has a clock, I will remove the clock and replace it with the pressure gauge.

Virtually any 2 1/16" gauge will fit in the 2 holes next to the cluster with easily obtained parts.

I've been toying with an idea to remove the center vents to mount three additional gauges in the dash. The turbo three-gauge panel could be modified to fit beneath the existing three gauges.

I'd like to include an oil temp gauge. Also, a fuel pressure gauge might be an interesting idea. And a turbo temperature gauge would be a welcome addition. Maybe an ammeter.

With the clock gone, you could have eight instruments in there.

You could also mount a modified 3 gauge pod on top of the dash, above the existing 3 gauge panel. Click here to see an example. I was thinking of trying to put a gauge in place of the small air vent to the left of the steering wheel.

ok. I've gotta go for this.

You've got the main cluster plus 5 other 2" positions using the turbo cluster.

Whaddaya need 3 more for?...

Lemme guess...

Clock

Volts

oil press

oil temp

vacuum OR turbo

ambient temp

(auto) tranny temp

exhaust pyrometer or air/fuel ratio

geez, that's a lot of info, Don. Maybe you can add a couple of a-pillar pods, too. Driver Blood Pressure? Driver Rectal Thermometer?

I think there was an R-Sport pod to mount 3 more above the useless center dash speaker grille, too, Don. Maybe I can come up with some more...

Talk about too much information!

Well, let's see.

System voltage.

Charging current.

Oil pressure.

Oil temperature.

Turbo (or exhaust) temp.

Boost/vacuum.

Ambient temperature.

Fuel pressure.

Now if modify my old R-Sport cluster (from my '75) to fit my '82, then oil pressure and voltage are provided, so I can reinstall my clock.

The remaining spot could accept a digital compass.

But, yes, I like your idea about real-time blood pressure monitor. Hell, with all that data it's likely to drive my pressure to 600/300. Oops, that's 40bar/20bar.

And I'll never actually drive the car, so I won't need the digital compass, so I can install a fresh-air vent to cool the sweat from my face. I mean, all those numbers, those numbers................

And I'm designing a new panel to replace the ash tray. I figure six more switches.......

Sure it's an oil pressure gauge,10 bar, just like the R-sport gauges in 74-80 Volvo's.

"PSI: 0-150. Can't imagine what this was used for because 150psi seems like a LOT for oil pressure, unless SAABS are goofy."

I've seen an 8 bar gauge out of a Porsche, so I don't think it's too odd. Maybe for some cars the 8 bar gauge is like the 3 bar Volvo gauge (not quite enough) and the 10 bar is the better choice (like the 5 bar Volvo gauge). I don't really know, I'm just offering a theory.
