I believe its jdm k20a manifold cut and welded into to a shape to allow throttle body to suck in direct air from the front of the engine.

brotato, i made a mistake by not reading his question carefully.
i hope this thread will not become a RBC vs RRC vs RSP or JDMYard IM thread.

afaik, yes software simulation will be used to theoretically calculate IM design.
how accurate or perfect it will be heavily depends on the programmers.
actual results will probably very close if software developer have F1 budget.
