Not saying this is gospel, just offering someone else's opinion based on some calculations they did.
This is true, that is, the hole can pass that much air - that is the maximum amount of air that will pass through a hole that size. But, Adam needs a lot of other things to flesh the calculation out as to how much air a motor can pull through the hole - cam specs, plenium size, and lots of other specs about the motor. The URL that Adam posted on is here, for interested parties, but please bear in mind that Adam indicates a lot more would be required to really know anything about how much hp the hole will support.
