HP vs weight

[Cary Cumberland]

Has anyone ever done studies about what the performance difference would be with lowering weight of a plane vs increasing HP? For instance in an eagle, if you assumed an empty weight of 1050 and HP of 200 vs an eagle with an empty weight of 1100 with 220HP. I am thinking cruise may only be a small gain but which plane would climb better given the same prop? I know there are probably just so many variables that come into play but I see many people jacking the HP up on planes but with that sometimes the weight goes up. If you could lower the weight and HP is there some type of algorithm that could give you the differences? Anyway I always wondered about that.
