Which gauges are most important?
 

Besides the Speedo and Tach, which other gauges do you feel are the most important to have in a dual purpose daily driver/road race autocross car. I have openings in the dash for six (6) 2 1/16 gauges. These were my thoughts in no particular order;

1. Oil Pressure
2. Oil Temp
3. Water Temp
4. Volts
5. Fuel Level
6. Fuel Pressure

Any thoughts on this?

That would depend on how many holes you need to fill. If I had to lose one it would be fuel pressure. EFI engines will let you know if fuel pressure isn't up to par.

I have six holes to fill. If I don't need the fuel pressure, what would be a better gauge to replace it with....trans temp, air/fuel??

Analog clock :D

I'd do an AFR. If it was blown, EGT.

if its auto consider tranny temp

That's the same set which I chose. Fuel pressure is pretty uninteresting, although I can monitor it through my ECU so if I didn't have that one it would be ok. I'm not sure what else I would add, I think AFR moves too quickly to realistically be monitored by a gauge. There does come a point where you can actually have too many, although if you already have the holes, you may as well at least add something. :)

Yep, I'd take AFR over FP.

If you are gonna drive it hard on tracks, in my opinion, a big red oil pressure light is the most important! The gauges are almost just "cool to have" in comparison :D

I do love much gauges though.. :)

if its auto, your on the wrong site :buttkick: haha

What exactly is a daily driver road race auto cross car?

So you have 8 holes in the dash? Man that is a lot.

That's funny!

It's just what it says. A car that can be driven everyday if you desire and if you feel the need for speed, you can take it to an autocross or road race event and have some competitive times.

Yes 8 holes in the dash, the same number of holes Mark Stielow has in Red Devil and Mayhem.

I liked having an AFR. Once in a great while I'd develop a slight ignition missfire which showed up as the AFR going lean. I wouldn't feel the miss but it showed up.

i'd leave it 6 hole (excluding speedo/tac) and set up another or nicer ac vent. too many gauges can f up a pefectly nice dash or make it look like a MiG cockpit.

The standard 6 gauges plus oil temp to make 7.

The oil temp gauge can be wired with a toggle and you can stick senders in the trans and rear end as well. Then just flipping the switch you can cycle between engine, trans, and diff temps quickly.


There was a Stewart Warner ad that ran in the magazines in the early 80s. It was a picture in the cockpit of Swamp Rat whatever number and there was one gauge in it......oil pressure.

That's a pretty cool idea.

That is a pretty cool idea! Needless to say the oil pressure is by far the most important, correct?

I remember that....just need a 4 pin switch for 3 senders.
