Constructing your own Intake Manifold

Intake runner length is TBD but is going to be around: .5m
Material: Aluminum
TB placement is perpendicular to runner direction (still working out the finer details)
Plenum is still in the design phase (currently working on ensuring proper distribution of air between all runners)

Consequently after talking with other tuners and fabricators they suggest I use a 75mm TB as 90mm TB is overkill for what I'm planning on.
