Another thing to consider is where the hell would you cram a dual turbo setup in this car...dunno if you've looked under the car but theres not much room under there for getting too crazy with the turbo setups.

That's not the whole picture.
I did a rough calculation comparing the moment of inertia between 2 43mm dia cylinders vs 1 60mm dia cylinder. Heights were adjusted so total surface area was the same. The 2 43mm cylinders have only 74% the mass and 38% the rotating inertia of the 1 60mm cylinder.
While turbines and compressors are obviously not solid cylinders, the same principle applies to twin vs single turbos.
So while you have 50% the exhaust flow per bank you are only pushing against 19% the inertia.
