.......and in reply I say!:

I am not so sure about the extremity of the problem of power claims,
unless the US is now getting even worse than here in OZ (and these
things all come from Asia anyway, right? G).

I have a "2.5HP" direct drive comp, quite cheap, that delivers about
7CFM at 90 PSI. This gels with the 3 CFM/HP claim. So it is _not_
claiming to be a 2.5 HP machine, when actually it's only say 1/2 HP
usable, with a stalled current to make it 2.5.

So I would be careful about assuming that this 3/4 HP motor will
deliver as much as a modern "2HP" motor or whatever.

You're looking at things just fine. Most of the consumer grade compressors
you see today have a rating called "peak HP". What that really means is that
they lock the rotor and measure the peak current drawn as the windings
smoke, then calculate a theoretical HP figure from that. It is totally bogus.
HP is *zero* with a locked rotor.
