I thought I would post these facts which were hiding in my book collection.
The Raf engine in the RE8 is variously quoted as 140hp or 150hp. With this power rating if you do the maths the RE8 has less drag at any speed than the PFalz D111. with 160hp engine. I assummed the RAF engine to be doing about 1500 rpm. I found a reference to the earlier 80-90hp version doing 1800rpm. Then discovered that the RAF 140hp engine actually produces 160hp at 1800rpm. I have not recalculated the maths yet but I knew something had to be wrong.
