Im beginning my first turbo build and today I decided to dig a bit into what gauges ill be using. I want the interior to be clean and simple, im not interested in having a ton of gauges or any on the pillar - I'm planning to have a SARD Stack cluster displaying oil T, water T, fuel P, and of course speed and RPM's, also a custom dashboard with three gauge ports where the vents are located on the OEM panel. Ill have a Turbosmart eboost2 in one port, with an AEM wide band AFR, and AEM fuel pressure gauge in the other two. What I want to know is if I use a wideband AFR, is an EGT gauge needed? If not, ive been reading a bit of the pro's and con's, what do you guys personally prefer to use over the other?

 

Is this a racecar? or a street car? If it is a street car, why are you willing to spend $1200 on a cluster meant for "mainly" a racing application.
I know it is your money, but it can be way better spent on the build itself.

I would ditch the fuel pressure gauge idea and get an oil pressure gauge. WAY MORE IMPORTANT. A fuel pressure gauge is easy enough to install on a fuel rail.

 

It will be a street car, id like the Sard cluster for asthetics and to also keep from having to have gauges all over the interior (personal choice), I have the water temp, oil temp, and fuel pressure in the cluster. I also meant to say the third gauge in the dash will be an OIL pressure gauge, that was a typo.

 

Im getting a great deal on the stack cluster, and it gives me the option to display more / different options down the road if needed, the car will be a street car as well as a show car and ill be doing some autocross down the road. The initial idea of this post was about the wide band and EGT gauges though.

 

I know alot of guys that either do not use any gauges. Some with both.

If you understand how to read EGT's, or recognize a range of where your exhaust temperature readings for your turbo setup SHOULD BE, then it "MAY" be useful. Most use it as a back-up for AFR, since you can see a lean mixture through higher than normal EGT's and by reading the spark plugs if the AFR gauge were to fail. By the sounds of it, your build is more for show. With that being said, for a fairly low-to-moderate power setup, I doubt it will be needed or useful to you.
