Actually, now that I think about it, one place they did convert to plastic was the mechanical fan.

We addressed this already. They didn't have a *need* to do anything from 1990 until 2011. Why would they do anything if they didn't have to?
It appears that you simply wish to remain skeptical and that's fine. It's your world after all. We have people here who have done this and their result has been discussed.

Um, yes it is. It's not simply irrelevant bc you are unable to wrap your head around the work a motor has to do to get something moving. You go right to weight of a fan which demonstrates clearly that you're missing the point of parasitic loss and increased efficiency on the transfer of power.
You want your mind blown a little more? About 14 years ago, I removed the (non-working) A/C compressor from my M10 that I've driven for 26 years. Result? Much better revving to redline. Easier movement of the engine up and down the range. Think that showed up at the rear wheels? Why? Because the almighty dyno is the end all be all of power efficiency?

And if you've taken off a parasitic loss, ie the fan, and the car indeed accelerates faster, the only way that's possible is if more HP is being delivered to the wheels. It's physics 101.

No, it's not. Did you stop reading so that you could breathlessly enter a nonsensical reply? Try to get through the whole thing without holding your breath, stomping your feet or crossing your arms.
You're not thinking about this the right way despite our best effort. You think you understand this and cite physics that you clearly do not understand as your reason.
(Read closely, this is the point) The engine did not deliver any more HP to the wheels than it did before.
ZERO HP is made available. It is made more easily. Uphill vs down, friction vs less, simple vs the way you're making this.
I think it's great that you wish to remain skeptical, but I do not think that anyone's experience here is going to change your mind. Why? Well, we've issued our experiences here for you. You choose to speak of physics but are able to apply only simple math.
