30 psi boost gauage
 

yesterday saw two different kind boost gauage
both made by autometer...showing 30 in/g vaccume and 30 pis boost...
but one of them has the needle rested at 30ing vaccume and the other one rested at 0..
where are the different?....

Re:30 psi boost gauage
 

You sure they both measured vacuum? Maybe thats just how Autometer sets up one of their guages.

Re:30 psi boost gauage
 

Mine rests at 0. dunno.

Re:30 psi boost gauage
 

don't buy one that is not set at 0.
i have seen ones that have been dropped that are not correct.

some boost gauges don't have vacuum and just have boost on one side. i would go with the 30/30 one you saw.

I have a vdo one from summit racing for $27.95

OH U KNOW WHAT just took a clear look i think it has memory and cos $2xx!!!? um...um..

Re:30 psi boost gauage
 

they wouldn't show a fucked up one tryin to sell them lol
it probably just rests at 30 vacuum istead of the normal 0/0

Re:30 psi boost gauage
 

I bought one that was an autometer ultra-lite series. You could chose from two.... Both had the 30psi Vac, and one had 20 psi boost and one had 30.

I went with the 20psi boost max becaue I wont be hitting that and the numbers are larger and easier to read. Hope that helps

Re:30 psi boost gauage
 

The reason it's not at 0 is because it's an electric gauge and not mechanical. That particular guage has a memory and also a warning feature.
Do not buy a mechanical gauge that is not set at 0.

hey its fun to think you're running 30 psi instead of 5 with those mechanical ones that aren't set right :)
