Booth....... An electric version of the Fuel psi can be installed safly inside the car and is important for blown cars. Also boost is important to know how many lbs your pushin out.

persoanly, I did boost and oil press... a/f or fuel press wouldnt be a bad idea either tho

boost and fuel pressure at a minimum.

i had an aftermarket boost and air fuel pressure(useless)
they were installed by purplenotch... he does quality work. hit him up if you need someone to install them.

thanks guys, fuel pressure and boost, any others that would be useful??

electric - short sweep or full sweep or, mechanical, digital, ???

i am looking at auto meter, any suggestions, looking at phantoms they look like they match the stock dials for the most part.

purplenotch if you are interseted in some side work i am interested in getting them done, i would be guessing so you know better than I.

as for the wideband what options are out there?
i saw a $400 gauge but i am not sure i want to fork out that much.
what are the reasons to have a $400 gauge??

I never liked the idea of running fuel lines into the passenger compartment.

The fuel Pressure gauge comes in different PSI scales.
0-100psi
0-30 psi
7 bar

which would suite me best?

you want 0-100. 0-30 is for carb setups and bar is for rice

when i get a supercharger i'm gonna get water temp, oil pressure, oil temp, boost, fuel pressure, wideband, egt, trans temp, and amps

You only really need 3-4 gauges depending on the setup.

If you run an intercooler it's nice to have a water temp gauge. California can have wicked hot heat and in stop and go traffic your car will start to boil fast.

The other main gauges to have are fuel pressure, boost, and a wideband like stated above (LM1, dynojet, AEM). The wideband will tell you what your a/f mixture is at with real world load on the car. Most of the time when you pull a car off the dyno with a a/f of 11.5, the real world a/f ratio with real world load on the motor is around 12.5. You more or less can sometimes take a point away from the air fuel ratio. I've seen it many times, and i've seen it burn a few motors up also.
