I'd say they reduce the loss caused by engine "friction", engine revs up easier. as you said, after the lightening if of course "looses" the revs easier too.
Reduces engine intertia?
but don't think this is the ultimate question here, as is not wheter one should think of tuning N/A or just turbocharge.

Short answer.
Lightening rotational mass does not "make" hp. What it does do is reduce parasitic loss. For example. Turn the engine off, and try to turn it over with your hands...It takes a lot of force or work over time (hp). Making the engine rotate "easier" allows hp that was made during the combustion process to be used to turn the rear wheels, as opposed to turning the crank.

You simply got to think of it as weight loss. mass rotating at crank speed carries a multiplier of at least 6x and mass rotating at axle speed 3x. No hp gains, just less weight.
