Flow numbers and max HP potential

PRH said
What I’m saying is, I have built numerous motors that have made more than what the .26hp/cfm forumla says is possible.

As with all builds...... one parameter isn’t going to define what the peak output can be.

Fair enough. I'm fully aware of that and these numbers being tossed around require a lot of other work. I remember seeing a build years go where a guy was able to get better than 2.1 HP/ci out of a 340, through a carburetor. To me that's like magic.
