...."Re Fareastdrivers comments on the Centaurus and Sabre. According to Wiki, and I'm pretty sure I've previously read it elsewhere, an experimental Sabre produced 5,500 hp on test. That's spectacular from 37 litres"...
Puts the Wright Double Cyclone (2600 cu in) in the shade: 1,600 hp from 42.6 litres. And the Merlin 266 produced the same 1600 from only 27 litres !
The payoff was legendary reliability, as it was so lightly stressed.
