how accurate are the oil pressure and water temp? also which fan turns on first?
Finishing up my turbo install. I decided to keep my gauge setup to a minimum and simple. going with pillar gauge pod and have room for 3 gauges only.
wideband/boost and something else.
two of my main picks are either water temp or oil pressure.
but on the 1998 ive read that the water temp are functional. but just how functional are they? would you trust it enough?
how accurate is the oil pressure?
if you have room for one. which is least accurate on the factory gauges that you would install an aftermarket?
water temp or oil pressure?
my other question is which of the two fans turns on first(radiator fan) passenger side or driver side?
I was able to keep one of the fans and wanted to wire than as a primary fan. installed a pusher as a "a/c" or backup fans if one doesnt cool it enough.
thanks

In the factory setup, both fans always run together. There is a high speed and low speed setting, but when engaged they will be on at the same speed and always at the same time.
For a '98, the water temp gauge is far more accurate than '99+ in terms of registering temp changes within the ~180-230°F zone where the '99+ are generally a dummy instrument. Having said that, the gauge face itself doesn't offer much information - but neither does the OP gauge.
If you want *real* information that's detailed, I'd probably not count on either. But in this case you might want to concern yourself more with oil pressure on a better indexed gauge as the temp gauge will at least tell you if things are moving out of your comfort zone.

You could check the accuracy of your water temp gauge with a rented infra red heat gun or even a calibrated thermometer stuck into your radiator (fill cap off). You only need to worry about accuracy at normal operating temp (195-230). I tend to think the water temp gauge would be more accurate due to its fairly wide range.

with that said i may just go with oil pressure. my only real concern with oil pressure is you either have it or your screwed. by the time you notice it on the guage too late. but at least you would know to shut it down to prevent any more damage. but would the factory be sufficient in telling you that youve lost oil pressure?
water temp ive watched before and have always shut it down before it overheats. but water rises slower vs pressure drop.
