Have been reading the threads on engine performance. My question is does a 180hp engine running at 2350 rpm and a 150 or 160 hp engine running the same rpm indicated the same true air speed at same given altitude, temp.

It is my theory BSFC (brake specific fuel consumption) is about the same with all Lycoming engines, i.e., a 0235 burning 6 gph produces about the same HP as the 0360 burning 6 gph.
That being a fact (?) maybe, the limiting factor in comparing one Lycoming to another is its rated HP. The prop matters of course, but set the same fuel flow leaned out and generally the HP and performance well be similar.
