Gearing has nothing to with throttle stop testing, except in that during testing, gearing is fixed. Gearing does not limit top speed during throttle stop testing.
At least you've moved away from the irrelevancy of BSFC. If you want to actually even be in the ballpark of the discussion, BMEP would be more relevant.

Your presuming that the mechanical efficiency of the powertrain is constant. It's not. That's addressed in the SAE Paper.
Brake Mean Effective Pressure will impact torque and horsepower, but BSFC will determine the thermal efficiency for which that BMEP is developed.
Gearing absolutely limits top speed in the example of the Corvette Stingray, if W.O.T. is taken as the throttle stop?
