[s-cars] question for those with boost gauges

[David Kase]

He does mean "inches of mercury" (unless something is horribly wrong) 
and I think you mean "inches of mercury of vacuum", not "inches of 
vacuum".  There is no such thing as an inch (or pound) of 
vacuum/boost...  :-P

>Mike: I think you meant 13 inches of mercury (Hg).  Anyway, at idle it varies. When the car is first started and the rings, etc. haven't fully expanded (with heat), I will get in the order of 10 or 12 inches of vacuum.  When the car is warm, it will be in the 14 to 16 inches of vacuum range.  They only time I get 20 inches of vacuum is when the car has been run hard and then the throttle is closed quickly.
