what is the difference between mechanical and electric boost gauge? and will a 2" fit in the stock ss/sc pod? thanks

 

mechanical and electrical differ in thier reading i believe. a electrical reads from the PCM which i beleive isnt as accurate and a mechanical reads from the O2 sensor which is more accurate, our stock is electrical i believe


i know that i know the info but i think i might have got it jumbled around haha.

 

A mechanical will read straight from a vaccum hose running off the intake manifold/super. It has nothing to do with a O2 sensor. An O2 sensor reads air fuel ratios in the exhaust

 

yah, thats what it was haha. but otherwise i got it right eh? i shoulda known that! i installed my boost guage and had to attach it to the vaccum line..not the 02 sensor haah

 

^^^^its all good we are all just trying to learn new stuff.

 

bump does a 2" fit in the pods

 

it'll fit, but if its loose just take some electrical tape put it around the guage to where you dont see it of course and basically it acts like its part of the guage to where it makes it nice and snug into the guage pod

 

2 and 1/16th will fit in the pod.
so yes 2 inch will work.
i had a 2 inch in for a while, i just put a wrap of electrical tape around the inside of the gauge to keep it snug


edit: haha beat me to it

 

lol its all good

 

So electrical is better? and if so, how much more and is it worth getting Electric over mechanical

 

hey thanks guys +rep guys

 

Neither one is better imo. The difference in the reading is so minuscule it doesn't really matter. The only problem i have heard with the electrical ones are that the spring gets worn out and it doesn't function properly after a while. I heard that was for the stock ones at least.

 

lol, sounds good to me. The electric was more money any way so U just talked to me into saving a few bucks. Is there a big diff in install on them?
