Ok, but that still doesn't answer my question of what specifically SpaceX did differently. For instance, you said bigger temperatures are needed and that is limited by existing materials. So did SpaceX invent materials that could stand a higher temperature? |

SpaceX has the first flight tested, full flow dual turbopump engine.
As in there are turbopumps for both the lox and methane tanks powered by burning extra rich mixtures for each pump leaving enough unburnt lox and methane in the perfect ratio to generate the record primary thrust.
