You let the fact that Elon is a clown in a lot of ways lead you to think absurd things. Which, I must point out, also makes you a clown. Here is more info about the engines above.

The Raptor engine evolution reminds me of the quote variously attributed to Mark Twain, Benjamin Franklin and others that goes, “If I’d had more time, I would’ve written a shorter letter.” The amount of design-hours to produce the Raptor 3 is hard to imagine.
