Me and a friend were discussing this:

Water psi, or oil temp?

Only have room for one additional gauge on a blower motor application because the boost and fuel pressure gauge are taking up all the extra room on the dash. All the basic gauges there otherwise.

The real question is: Which of the two are more important????


I'm voting for oil because the motor has a circulating pump... I figure as long as the engne cooling is ok, the intercooler should also be seeing decent water.

Love to hear your thoughts and opinions

I'm not an engine builder so it will be interesting to see what someone that is will say but I would go with water press. My thought process would be that most of the time a high oil temp could be traced back to lack of cooling water so if you had a water press guage you'd see a drop in press before an actual increase in oil temp.

Oil temp...

I would say oil temp. If you lose water pressure, the water temp will go up within 10-20 seconds anyway.

And in 10-20 seconds you could crack an exhaust manifold. I vote water pressure.

I'm gunna say oil temp , but if you can make room on the side panel and add a few more gauges it surely would'nt hurt

I'd say do both if you can. Too much oil temp or too much water psi can have you pulling the engines out and rebuilding them. Even if you have to mount a seperate gauge pod, might not look the best, but it is what it is!

I would do away with volts and use both. Volts arent near as important as those two

Until the voltage regulator in the alternator takes a crap, and fries your ignition boxes.

If you have a GPS most have a volts display you can add to the screen.
