Wow, that's wild! How does the flow get related to the square of the
cross-sectional area?

Not so much. Displacement follows the square of the bore, but 89^2 is less
than 5% more than 87^2; so we're only talking another 5hp or so (without
other changes). At nearly $100/pony, not a lot of bang for the buck.
