Oh dear :o On
this C-119 page it says
The C-119 had two R-4360-20 Pratt & Whitney engines. Each engine had 28 cylinders in four rows and seven banks, 56 spark plugs, 7 Magnetos, 4 seperate circular rotating cams, and an internal super-charger. At take off settings, together they developed 7000 HP (7800 water injected) delivered to, two Hamilton Standard, four paddle blade, 14 foot props. The Pratt & Whitney R-4360-20 was the most powerful internal combustion reciprocating engine ever built.
Unfortunately while my eyes boggled at the 7000 hp figure, they missed the rather important word '
together !
Unusual way of quoting hp, but no excuse
The dash 20 appears to be the military equivalent of the -CB2.
