I think the whole "By the way, where did you get your engineering degree?" is pretty rude actually.
No disputing that the reduction of rotating mass will make a difference. The bigger concern for the sake of the subject at hand is how
big a difference. Saving 4 ounces on a light weight pulley is NOT going to make a difference that is even measurable on any form of test equipment outside of a major lab. I doubt you could reduce the weight (at least with any form of budget in mind) of enough rotating components in the engine these cars to make a measurable difference much less the claims of some that the car "comes alive".
The physics is one thing, the application of them at the level of lightweight pulleys is another.
