Mechanical VS electronic boost guage

[TheShit]

which do you think is better?

As long as either is getting actual manifold reference, the display type is inconsequential

I would choose mechanical every time. It is a direct reading, without using signals and algorithms. My opinion, Im old school though.

Electronic, feeding into a data logger.

Love my snow methanol controller/digital boost gauge. Mechanical ones are awesome too, but with this I don't have to worry about running a boost line through the firewall and running into potential kinks. Just wires going to an external boost sensor mounted on my charge pipe.

I like that gauge, you are correct about running the line through the firewall. It can be a royal pain.

Replying to you since it says you are in Colorado. If you live at high altitude, don't get electronic unless it has a function to adjust the zero point. I have an electronic sensor that is always off by 2-3psi because it doesn't take altitude into account. A mechanical will be correct at high altitude, but an electronic will be wrong.

Yup, I had the P3/raxium gauge on my last car, and it did have a "zero" function. I like it because it can also be wired to display all sorts of stuff like ethanol content (with an ethanol sensor), AFR, Coolant temp, Ignition timing etc.

I’ve been using Autometer Pro-comp mechanical gauges for over 28 years. Never been disappointed or ever had to question the accuracy.

This.

The AEM X-Series boost gauge is what I use. It has a 0-5v MAP output that I run to my HP Tuners MPVI to data log actual MAP. It also has a peak memory recall that I find to be more convenient than trying to look at a gauge in the middle of a pull. Only downside is the gauge’s MAP sensor is sensitive to vibration. The instructions specifically state not to directly attach the sensor to the engine. I screwed my (first) sensor straight into the boost reference port on my Whipple and it died in about 8000 miles. I now have it mounted remotely via a vacuum line.

Another nice feature is it’s really slim and requires very little depth to mount. I designed and 3D printed a mount that goes in my center vent and angles the gauge towards me.

Just for fun I got a Scangauge 2 obd 11 reader that has a bunch of parameters to keep watch on real time one of which is "Boost" its a cool little device (a bit old school) its also a code reader. You can display "4" parameters at once. Also, bunch of diff led lights to match your current set up. I had it on a mini cooper S supercharged, dang I miss this little car
