The chamber melting on raptor2 is concerning. I hope they find a solution

  Not really concerning. When you are designing a rocket engine that’s what it does before you’re done, it melts and explodes. In fact it’s what all rocket engines do past their limits. If that wasn’t the problem you were having, it would be concerning.

  Remember that they are trying to push raptor 2 to even higher pressures, and try to be as efficient as possible. And they want the engine to be rapidly reusable hundreds of times. I am sure they could run the engines at a lower chamber pressure with massive amounts of film cooling and have it be safe for a single launch. It would still be a very high performance engine by today's standards. 330 bar chamber pressure is just nuts. Also, if the biggest remaining problem is the chamber melting, that means that they think they have the pumps under control. Which is a major achievement on its own.
