Many published top speeds have absolutely nothing to do with actual drag-limited top speed, which is what you'd be after. The recent Corvette would be an example.
The 2020 Corvette Stingray has 495-bhp and a top speed of 184-mph.
This Corvette will maintain 184-mph in 8th-gear, at 3870-rpm, and 327-horsepower. It's gearing will not allow a higher top speed even though it clearly has the power for it. Context!!!!!!!!!!!!!!!!!!!!!

Maybe go and read what I have written here before about throttle stop testing technique? So that you understand what it involves?
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.
