Boost question

Been doing some reading on forced induction applications. For the bigger applications most guys drop their CR to the 9 area and lower if its a strict race car is what I have gathered. But it seems like you would be taking a step backwards to run boost.... Why not make a solid motor to run boost at a higher CR?

I understand that a lower CR will be much more forgiving to detonation/knock from fuel issues, or tune issues, but can anyone explain why you see more of a power gain from a lower CR compared to a higher CR with the same boost level?
