Measuring the torque of an engine is a trivial chore when the load is
a propeller. So long as the engine is allowed to rotate around the
axis of its crankshaft, the amount of torque it produces can be
measured using nothing more complicated than a bucket of water.
(Hint: 'A pint's a pound the world 'round.' ...according to Miss
Rose Saghetti, my Fourth Grade teacher :-)
Everyone who has tackled VW conversions in a professional fashion
eventually realizes the need for a torque stand. Over on the AirVW
list you'll find a fair amount of discussion by those of us who have
actually built such a thing. Often times as far back as the late
1960's.
The error I wish to correct has to do with my recent reference to the
only VW torque-stand article to appear in 'Sport Aviation,' which I
referred to as '...the WHEATLY article." I should have written
WHATLEY, as in Vascoe Whatley Jr, EAA 55115, whose article 'The
Whatley Torque Stand,' appeared in the January 1982 issue of SA. In
the article Mr. Whatley's 2332cc engine (142cid) produced about 55hp @
3400, which was in general agreement with engines built and tested by
those of us with torque stands.
