Hi Tom,
I think there is a small error in your area calc. A = pi* r^2, so
A = 3.14*(2.5625/2)^2 =~ 3.14*1.28*1.28 = 5.15 sq. in.
I'm hoping to get the engine running pretty soon to get some idea of how well it is going to work.

So lets take your butterfly size of 2 9/16 inches.
Bobs butterfly area = (2 9/16 / 2) x 3.14 = 4.02 square inches
Max supported airflow based on their rule-of-thumb = 4.02 x 140CFM = 562CFM Max HP based on these (100HP per each 140CFM) = 402HP
The difference between the actual HP your motor will make and 402HP is throttle-movement that would do nothing for you. Here's the website:
