. The tach is supposed to be above 7,800 all of the time, as there is no
power under that. Sometimes I catch him under reving and we have to talk.

  I think this statement from Lynn makes the point that auto racing
actually may be a reasonable basis for determining durability of the 13B in
an aircraft application when the desired output is about 180HP @ 6000
RPM.  I'd guess if this engine peaks at 245HP @ 9450 its at or above 180
when under load for a pretty fair amount of the time during a race. Its not
at 100% power but its above 180 for far longer than the fraction of a
second thats been pointed out previously. Isnt that what counts? At least
for those of us who would be satisfied with that amount of power.  :-)
