Vacuum Gauge= Boost Gauge

Mar 10th, 2003, 01:24 AM

Hey a friend of mine is giving me an Autometer vacuum gauge and I remember reading somewhre that you can use use a Vacuum gauge as a boost gauge you just have to read it backwards. I was wondering if that information was correct if so how do I read it?

Any help would be greatly appreciated.

There is a boost gauge that shows vacuum, but as for using a vacuum gauge as a boost gauge, I've never heard of that.

Vacuum and boost are completely different, No it will not work like that. When boosting Vacuum and boost need to be measured.

boost will cause a vacuum gauge to run in the opposite direction... most likely the gauge needle will peg on the zero pin.

Just buy a boost gauge.
