Throttle Bodies size??

[Toyotus]

Maybe a bad example of Toyota attempting to re-engineer an ancient engine, but the Blacktop 4AGE has 45mm throttle bodies, injectors in head, and only a claimed 165hp, so something like 41hp/cyl, compared to the 65hp/cyl listed here for the 45mm throttle body. It appears they were just throwing more air and fuel in hopes of higher outputs, as opposed to smaller diameter increasing intake velocity. Similar to the 16v 4AGE attempts at more power with larger intake ports, and steeper valve angles, then later going to shallower angles and smaller intake ports.

Interesting figures though, obviously lots of trial and error I'm sure too!
