Hey guys just curious whats the difference between mechanical and electric gauge?

 

Usually, a mechanical gauge has the whatever it is sensing brought right up to the gauge itself, where it is then changed into a needle movement. Like and oil pressure gauge for instance, the oil is actually brought the inside of the gauge, where it would fill an aneriod chamber, expanding under pressure, and that expansion is that geared into the indicating needle. This is pretty old school.

An electric gauge senses the pressure using a remote sensor that turns the pressure into a voltage. That voltage is then sent to the indicator gauge, which is reality is just a voltmeter. Even this is now old.

There is a new direction now with gauges like the Autometer Nexus system. A computer recieves all the sensor inputs, and can display whatever you want.

 

Exactly! Well said!

 

yup.. well put, to add. our boost gauge is electrical. if you swap it with a mechanical gauge you will notice more exact boost numbers and quicker response of the needle.

 

so mechanical would be a little bit better for exact numbers?

 

yuppers...

 

Ya, mechanical is much quicker and more accurate readings. I had put a mechanical boost gauge in my Redline when I had it and it would bounce around much faster than the electrical one in the Cobalt.
