It's also a bit of a myth that one must pursue the highest possible compression. If you're at 8:1 and go to 9:1, you'll make 'more power' but less 'more power' than, say, a supercharger or a turbo or adding another 200 cubic inches.
Kinda stating the obvious, but one aspect seldom mentioned, the CR increase in power is not really RPM dependent, its across the entire power band..

Another downside to increased compression which has been obliquely referenced is that higher compression means less possibility of boost.

Along with what Reed noted, another downside of increased compression is the tread on the rear tires goes away faster.
