Are you saying that you can enter a straight at 177 MPH at WOT
and not increase speed at all after 10 miles but at lower altitudes
you will accelerate?  Is this on a flat surface?  Are you re-tuning
for altitude (changing jets and timing)?

If that's the case, then perhaps my assumption that power decreases
linearly with density is not valid.  However, my (limited) experience
with non-turbo piston aircraft is they go a bit faster at altitude
than at sea level, even though power has gone done.  There's also an
optimal gearing assumption.  I suppose it's also possible that your
gearing is more optimal for lower altitude and you're on the wrong
side of the power curve at altitude.  If you're at terminal velocity
at altitude and go downhill, can you hold the speed increase when the
road levels out or do you slow down again?

Argue away.  Sometimes it's the only way we learn anything.
