Not sure the relationship, but they say 600PSI chamber pressure, or about 20 bar. Spacex is push 200 to 300 bar pressures. I would think this means they're currently at a low ISP. The challenge with RDEs has been keeping them lit, I e. Keeping the detonation wave going indefinitely. Once that's done they can work of efficiency. Seems like they're at that point now.
- wolfram74 4y agoPressure can tell you about thrust, but I don't think its as strongly linked to specific impulse. However looking at the wiki article on the RS25 which is pretty high up there being a hydrolox engine, I see it's also got a chamber pressure in the 200+ bar range.
