Forget thrust to weight ratio! One key metric for Starship / SuperHeavy that's vital is thrust to area ratio!!! Raptor is currently at 270-ish bar & 1.66 mN for SN5/6/8. It's slightly below Merlin, but once ramped up to operational levels, it can easily match and exceed Merlin!

Raptor has now run for 90 secs at 300 bar chamber pressure before encountering issues. 210 mT-F sea level operating thrust seems achievable with no major changes.
R-Boost variant is aiming for 300 ton thrust at 300 bar with same nozzle exit area. Will need bigger pumps.
