Making Life Multiplanetary talking points about going to mars and his BFR to which a clip of the engine testing of the Raptor was commented on.
Over 1200 seconds of firing across 42 main engine tests.
Longest test 100 seconds: 40 seconds typical for Mars Landing.
Test engine operates at up to 200 atmospheres

He mentioned growth to 250, then maybe 300 atmospheres. There's a lot of growth potential built into the basic chamber design. I suspect it's the turbopump assembly that is the pressure-limiting factor.
