Why? Do the Archer's engine components wear less at high RPM than an
engine on an Arrow?

Yes they probably do wear less. They are under less load for the given
circumstance. Cylinder pressures are much higher in an engine at 65%
power 2300 RPM than they are at 65% 2480 RPM.

But a far greater effect will be the additional wear from friction of
running at 2480 RPM instead of 2300 RPM - a significant increase in the
number of friction cycles per hour. I'd say the Archer's engine
will wear more quickly.
