Why does the shuttle throttle on ascent?

Of course, on some engines, that was grounds for grounding the aircraft
to inspect the engine, to see if it was damaged from exceeding 100%
power.
On the P-51 Mustang, this was called "War Emergency Power"; it would give
some extra zip, but would also destroy the engine in around ten minutes
after engaging it. :-)

Actually it's 5 minutes. WEP on my V1650-7 Merlin in the 51 could be
achieved by breaking the throttle gate . I never used it...actually never
needed it really. Under 5000 feet, normal max power at 61 inches gives you
all the power you need to exceed the operating limitations for the engine,
and at altitude on cross country, I was more concerned with saving a buck by
not stressing the engine anyway :-)
Also, if breaking the gate and using that extra 6" of MP, the Mustang should
be using 130 octane fuel and not the 100LL we poor folks have in the tanks
most of the time :-)
Does anyone still make the purple juice for the air races? I recall
that Phillips 66 used to...
