Boost gauge So I am about to get done with my F1A and 408 project and time to look into guages I got a Wideband and fuel pressure gauge so far ..Now my question is for the boost gauge should I use Electric or Mechanical....And the good and bad of each thanx
I also have a Cobalt elec boost gauge. I have it connected to one of the aux inputs on my HPT logger along with the wide band & fuel pressure so I can review that stuff after a run & keep my eyes on the track ahead of me.

electronic uses a transducer to convert vacumn/boost into 0-5v signal, sends it via wires to gauge which usually displays as a #
electronics are nice sometimes as you aren't running a vacumn line through the firewall/cabin

The gauge I have actually comes with a MAP sensor. You hook the vacuum line to it and then run the electrical lines from it as well. I just question its accuracy mainly because I have a procharger and it will read 3psi revving in neutral.

I vote Zeitronix lcd electric gauge. They read EGT, AFR, Boost/vacuum, and Lambda. It has one of the faster updates and also has data logging. I currently use one in my daily beater (1st gen dodge neon with an srt swap,) and I love it.
it works just as well as the 190.00 gauge imo part # atm-4603

Ya I thought mechanical would be more accurate cause it is a direct line to the gauge just wanted to make sure and ask questions before I order stuff ...I am gonna think about trying to put the gauge in my vent because space is getting tight than guys
I vote electrical all the way. The electrical uses a vacuum line just as the mechanical one does, however the electrical ones have been proven to be more accurate (not that the mechanical ones are way off though). I also have an electrical full sweep boost/vacuum gauge and I can tell you it is awesome, not to mention almost a must have for those needing to be warned about boost levels and being able to recall peak boost levels.
The only thing I don't like about mine is that I got the gauge that peaks at 30#'s of boost when I only make 15#'s. I am currently selling my gauge so I can get another electrical one that peaks at 15#'s.
Here's a link to my gauge. In it is a video of the full sweep electrical gauge in action for those who wanted to see how it works compared to the mechanical one.
