So, Vishnu's design has merit.

The problem is your equation is for static cross section areas and the Vishnu design is a tapered design. You guys must remember that the BMS uses a velocity stack style intake meaning the taper exists as well, just in the cone rather than the piping. Anyone that thinks there is a difference really wants to spend more money.
