I believe the guys are getting their fuel from a specific source, but I'm
not sure who handles that now.

Of course, on some engines, that was grounds for grounding the aircraft

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...
