To simplyfy it down, a turbo chokes on inlet volume not mass. So the 16g can intake like 600cfm, it doesn't care if its at 14.7psia or 100psia, It can only move 600cfm. So if a 16g chokes at about 44lbs/min when the intake pressure is at atmosphere (14.7psia), its moving about 600cfm, now you increase the inlet pressure to 30psia (twice the pressue of atomsphere ~2 times the density) It should be capable of flowing 88lbs/min.
Why don't you just have a single garret housing machined for it?
Because I can't find a suitably large housing for high boost, especially on a 2.3, and the 2.5 outlet on the HX30 dictates a T3 flange. Even something like a Garrett .96 T4 housing would be too small in my opinion. The 21cm2 housing is LARGE, and the divider certainly isn't going to hurt flow. On John's WH1C and HX52 setup, the HX52 has a divided housing, and it still comes on quite quickly. That car is unreal fast.
