Anybody have a boost guage hooked up and it didn't work..i don't have a boost machine hooked up yet, just running the guage to a 4 bar fpr with a **** installed...is it supposed to work before you have a boost macine hooked up?

 

it should, what do you have it hooked up to?
how is the tube attached to the gauge?

 

hooked underneath the driver panel...ground to the ground wheel, powered to the 75x bolt...tfitting at the fpr, with the nylon hose running from the single t part sticking out to the guage...that's pretty much it

 

did you push the tube far enough into the gauge?
mine didn't work because of that.

 

yup, it's pushed in pretty good..ill go try it again though...

 

alright i pushed the f(ck out of it into the guage, and it seems to be working somewhat, I think..it only reads up to 15lbs max, but i'm thinking it should be reading more boost than that with all the mods i have on it...apr 91 flash, 3" exhaust, airbox, fmic, etc...and everything's running just like it should, no boost leaks or anything like that

 

is your car a 180?

what is the vacuum reading at warm idle?

 

it's a 225..vac reading at idle is about 5-10,..well, it's only been at idle twice since i got the guage working, the first time was closer to 10, the second about 6..

 

hmm that's strange.

I remember my boost gauge was weird for about a day and them started acting normal.
you should boost around 18 PSI and idle ~17-20 Hg vacuum.

what gauge is it?

 

it's an autometer ultralite mechanical...i know it's hooked up right, so maybe it's the guage..i took the hose out of the guage and could hear the pressure coming from the hose at idle...not a whole lot of pressure, kind of faint, but steady...maybe it'll start acting normal like yours did
