[s-cars] question for those with boost gauges

[calvinlc at earthlink.net]

I just read this whole thread....not only have I laughed myself silly but I
have been scarred for life :)

David: Somebody needed to remind your Vibes professor of the power of the
communicative law of multiplication ;)

I didn't know that it being common meant it was correct.  I guess my
hang up all stems from my Vibes professor that drilled it into our heads
that torque is lb-ft, not ft-lb...

P.Eng. ?  Are you Canadian?

>>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.
