Both piston and jet engined military planes have carried water and

alcohol

for injection at take off.

Yep, and the Harrier jet engine (Pegassus) would quickly burn up in

hover

without help from it's on-board 300 pounds of water.  Good for just a

few

minutes of VTOL time.
Planes should be designed for the mission so I don't consider what the
Harrier designers did as 'cheating' either.

If the race was 1000 miles long the whole picture changes.  I'd fly it

at a

much higher altitude and cooling would not be a problem there.
To heck with artificial rules, they are why car racing is no longer
interesting.  The only rules I really care about deal with physics.
