I know some of this a matter of opinion, but which gauges do you ABSOLUTELY need?

I've heard A/F, Boost, Oil Pressure, and EGT...

Any thoughts/

 

i'd say A/F OR EGT.

The other two sound right to me.

 

the only one you ABSOLUTELY need is a boost gauge, hell, you could prolly even get away without a boost gauge if you knew what the wastegate was set at

 

Oil pressure and boost. Oil just in case an oil feed line etc. breaks or blows and the boost to make sure youre not slowly creeping to more boost than you engine can handle.

 

Boost and an A/F guage. If your looking for tuneability (and especially if your tuning by yourself) a wideband O2 A/f guage would be the way I'd go.

 

boost....and i dont think anything is necessary. id buy an EGT over A/F...

I've never used an A/F but i always hear people bashing them horribly. If it could just tell me as a warning my A/F was off i would spend the $40-50 but if its not going to be accurate i say just buy a boost gauge. Just get your car tuned and try to find someone locally w/ a wideband. then go out and hook it up during all types of different weather...then you will know if its cold what your a/f will be...hot and so on...

Thats just my thoughts.

 

I've fitted boost gauge, A/F (heh.. it costed me ~10US$ to make one) and addedd oil temp gauge (not really absolutelly needed, but nice to have).

 

since I want my project to be as sleeperish as possible as usual I'll be using one of the gauge cluster bezels as opposed to one of the A Pillar mounts where everybody can see your ----. The gauge cluster bezel = 2 gauges. And for me I'll be using boost and EGT. Without a wideband 02 an A/F gauges is pretty much useless unless something HUGE is happening under the hood. In that case though you wouldn't even need an A/F gauge. an EGT gauge can be more valuable.

 

boost, egt, and wideband a/f.

 

links to how you made it? I'm all into this making your own stuff.
