Kestrel is also one of SpaceX's earliest engines. They've made big
improvements on T/W of Merlin over the years, as every engine program
does; I expect a modern Kestrel would be closer to 100:1.
Ventions has an electric pump fed engine of a similar size to
Rutherford, I wonder if Adam London could be prodded to share its
weight.

upper stage engine and only has a chamber pressure of 135 psi though.
