Very Good Post, roylee62. and welcome maloner.
Think you have a very slight typo error with a couple of names (example: Compressor Maps vs compression maps), but the info posted is rock solid otherwise.
Your math is right on the money.
Your mention of the Borg Warner website "matchbot" has a really long link if you do a search on that program.
This link is much shorter.

then at the top where it says "visit" click on that and you should be there.
A few members have made over 700 hp at 13 psi of boost pressure with a belt driven compressor and a turbo system will not have the belt/compressor HP losses.
Welcome to the board.
