In all fairness Chris a new Honda Civic would stomp the hell out of any
300 hp Vanagon and especially Westy.
Frank Grunthaner already posted a list of possible conversions and their
published HP ratings.
I can remember Zoom Gear had a Idiot Wheel that worked like a Flight
Computer and it had the capabilities you are putting into a spreadsheet.
I haven't seen anything similar on the Internet because I haven't looked.
I'm sure that the application you are working on will be of some value to
some people.
Keep up the good work.
