Been shopping around for 3 gauges to fill the 42draft designs kit I'll be gettin soon and my car is stock for now, but I'm tossed up on what guages to get (other than boost, of course) that are actually important with a stock motor as well as when I begin upgrades. Obviously, you could probably never have too much "telemetry" as each guage does it's vital function in telling you what your engine is doing, but let's see a top 3 or 4 list....(guages that are not in the instrument cluster)

1. Boost
2. Oil Pressure
3. and trying to formulate an answer for the third based on general consensus...

BTW...I'm tossed up about A/F meters (yes, I know what they do and what they measure, but another guage of more importance maybe?)...

Thanks for the input...

 

3. EGT (or oil temp)

IMO A/F tells you how the mixture is doing...EGT is telling you how your actual ENGINE is doing.

However, IDK if they are a huge help. By the time you notice your EGTs are off the chart, its too late anyway. Id get some sort of a shift light style warning lamp for the thing.

Be realistic...if you dont think you are constantly going to be looking at the EGT, just get a oil temp or something. At least you will know when the oil is too cold or hot.
