Want to get boost and fuel pressure gauges for my Paxton HO install. What are pros and cons on electronic vs mechical guages. The most obvious is price. I can save over $200 with mech. I am looking at the Autometer Cobalt series. I plan to mount them in a two gauge cluster on the steering column.

i went with mechanical bro. i wouldnt know the difference but theyre working fine..boost that is dnt have fuel pressure

[hammeron]

yep, i also went mechanical, for
boost and electrical for the fuel
pressure gauge

Thanks guys. Here is the plan. Get a mech Cobalt Autometer and a Wide Band O2 A/F guage. Going for the two gauge steering column pod. Thanks again.

I run a mechanical boost, electric fuel pressure, and a Innovative XD-16/LC-1 wideband...

Electric gauges are cool. No lines to leak fluid. Nice.

And when talking about fuel that is a good thing...

Mechanical for Boost and you must go with Electric for the Fuel Pressure unless you want to risk running a fuel line into the cab of your car.

How do you like that WB set up. I found one on eBay for a good price.

Absolutely love it...

I also like that I will never out-grow this wideband...It can grow with your set-up...

You can use an isolator but by the time you buy the mechanical gauge and isolator kit you might as well buy the electric gauge and have a cleaner install.

mech or electric for a nitrous?

i want the Nexus autometer gauges for a procharged mustang. is just a Boost/vac and fuel pressure gauge good enough?

You will also want a wide band 02 sensor.

i was scared someone would say that, its $400!!!

[06RedfireGT]

Well it will tell you if your a/f gets out of whack so you won'tt blow the motor which costs a little more than a wide band

so is the fuel pressure damn near than same thing as the A/f windband crap?

[06RedfireGT]

no, the wideband tell you the ratio of oxygen to fuel in the combustion chamber telling you if you are running too rich or too lean, and the fuel pressure gauge tells you the pressure in the fuel rails.

damn so i got to get all three huh

A wideband is much more important than fuel pressure. I have some plx widebands for $260. I run mechanical boost and fuel pressure. I use an isolator for the FP so there is no fuel in the cab. The mechanical FP gauge is WAY better than my old electronic gauge. It has instant response and is more accurate (most electronic gauges have a slight lag). I can even know my boost just by watching the fuel pressure.
