Alright - sorry 'bout my retardation but when you say

bellmouth the runners into the plenum around 1/3 the height of the plenum
what exactly do you mean, that the runners should meet at a horizontal line along 1/3 the height of the plenum if the plenum is similar to a horizontally oriented sort of rectangle/box?
The bellmouth not coming in within 1/2 diameter means that say bellmouth was about 40 mm - then the plenum must be at least 20mm wide (along the axis of the runner/bellmouth) and at least 60mm high - right (so that the bottom 1/3rd is at least 20mm from the bellmouth).
If the throttle body is located centrally, would the flow favour the cylinders based on firing order or just pathlines of the flow?
I'm still trying to decipher how to calculate runner length btw
