This is the first flight of the new engines. They look so much sleeker and simpler than the previous two generations:

* And supposedly with a 20% power increase to boot!

Oh wow that photo is from years ago but you’re correct, this is the first flight of that design

Booster dry mass savings of around one ton per engine iirc.

The stats are pretty out there. Iirc just the fuel pump, which you can probably pick up and put on your desk, generates 100k HP.

Well, it's powered by bleeding exhaust from a very big rocket.

One of my favorite clips to give a sense of scale for rockets is this one. https://www.youtube.com/watch?v=70u748VALt4

I show someone and then I tell them, that's not the rocket exhaust. That's the exhaust for the engine that runs the fuel pump for the rocket.

Nope, Raptor is full flow staged combustion, so both the fuel and oxidizer have dedicated preburners and turbopumps each.
