compression = horsepower query

Giys, i've been reading many threads on here, but am wondering if thee is an easy answer to the following question.

Is there a ratio by which HP increases with increased compression if all other factors are equal e.g if a 360 is changed from 9.0 comp to 10.0 comp is there a direct effect on hp ?

I appreciate that there are many variable in making power, just wanted to know about this one:read:!
