Does the standard engine temp meter void the need of having an aftermarket water temp gauge? Aren't they pretty much the same?

Example, on my old GTR, I had a Power FC which displayed water temp. The needle on the stock gauge didn't move until the water temp got to about 60 degrees, and when it was up to temp the PFC could show a 10 degree difference and the stock gauge looked like it didn't move (or it moved so little it didn't help).

IMO the stock water temp gauges are not accurate enough for full reliance on them..

Fair enough, understood.

I have boost and oil pressure gauges on the wrx but i think that if oil pressure suddenly drops, its still going to be to late by the time i notice the gauge (esp if going fast and paying attention to the road / track / other cars) and shut the car off.

But that said, i got them cause they match the interior / dash

If it was me, i'd go oil pressure and exhaust temp though! 3 matching gauges would look good!

I like my oil temp, lets me know when car is upto operating temp and warns about overall motor temp as well.....

Delta Dash ftw! 25+ Readings, its not messy and wont attract attention from the cops.

I have boost and exh. thought along the same lines as Mat, if oil pr. drops will most likely be too late.

Each to their own however.
