Boost gauge -- electrical or mechanical?

1. Why are electrical gauges more expensive?

2. Is ease of installation the same for each?

Any other info you can spare is much appreciated. Thanks!

 

I know that some electrical gauges are easier to install. I got a mechanical water temp gauge. Damn that thing is a bitch, you have to drill about a 3/4" hole in the firewall just to fish the sensor though. As far as your boost gauge there is no problem with a mechanical. In fact that would be your best way to go, just tap it into the nipple on the manifold.

Thanks for your help. I'm not worried about going through the firewall. The mechanical ones do seem really easy to install. I am wondering how the electrical gauge actually works and how installation is different.

 

To the best of my knowledge the electrical gauges have a little vacuum solonoid that reads the pressure and has wires comming out of it that clips to the gauge. It's supposed to make it easier to install, in regards to just running the wires and clip through the firewall as oppsed to running a hose through. It also keeps the vacuum hose as short as possible.

Also with the electronic gauges you're able to do peak and hold functions, which comes in handy if you do alot of tuning.

 

Ok, that makes sense. Thanks!

 

I that electrical ones where more acurate?
