Static CR really doesnt mean much. Valve events dictate your effective (Dynamic Compression) in a more meaningful number. If you dont know what it is, its kind of a crap shoot on what CR to run. The higher the better for off boost, but too high will limit how much boosts you can run. I think 8.0:1 DCR is kind of a sweet spot for boosted applications, but thats just my opinion. It really kind of varies depending on build. Every car is different.
