I stand corrected.

For a compression of 9.5 you need a total CC volume of 111.6

For a ratio of 10.5 you need 99.88 CCs total.

One easy way yet accurate enough way to look at this is from having a 10 to 1 compression.

This would take a total CC volume of 105.4, then for each 1/4 of a point change up or down that you wanted to go then that would take a 3..3 CC change.
