I reported earlier that my engine was reading a vacuum guage indication of
7" at 4000 RPM and 72 mph, automatic trans, weight about 3700 lbs. on level
ground, and no wind. The current value is 9".  At 52 mph 14", this is
really loafing.

Anybody aware of a dyno test that indiates the horsepower at various RPM.
It would be cool to correlate how much horsepower is being used under
various conditions.
