Dick:
If the engine is pushing harder on everything, then the internal friction of
the drivetrain will be increased and will thus lose more power. That would
tend to mean that the losses increase with the power through the system.
Maybe not a scientific measurement, but seems sort of common sense.

Subject: Drive train HP losses...
Listers--- I have read in competent car literature, such as Road &Track,
that the horsepower loss thru the drive train and engine accessories are
pretty much fixed. If this is true, then as an example if a Triumph
engine puts ot 105 hp at the crank, and 85 hp at the rear wheels, the
loss is of course 20 hp. This would mean that if you gain 45 hp thru
modification of the engine, ALL of the gain will show up at the rear
wheels, as nothing was done to increase the drag on the drive train, or
accessories.
In short, it is not a loss based on a percentage of engine power, but a
fixed one.
