Gearing absolutely limits top speed in the example of the Corvette Stingray, if W.O.T. is taken as the throttle stop?

OK, you have not understood how throttle stop testing is done, and you refuse to acquaint yourself with how it is done.
That's fine, but it basically makes your criticism worthless.
- BSFC and thermal efficiency are
completely irrelevant to throttle stop testing. You really have to stop applying your existing schemata and think about is
actually being discussed, not what you
automatically think is being discussed.
- Throttle stop testing is not done at full throttle. That's why it is called 'throttle stop testing'.
- Gearing is irrelevant to throttle stop testing, except it should be done in the highest gear.
Look, don't worry about it. You don't understand it, haven't done it and are quite confused about it.
