Raptor 2 engines were achieving 230 tf (510,000 lbf) of thrust consistently by February 2022, although SpaceX expects to be able to tune engine parameters and design over time to achieve at least 250 tf (550,000 lbf). Moreover, Musk indicated that the engine production cost was approximately half that of the Raptor 1 version SpaceX had been using in 2018?"2021. In June 2022, Musk tweeted that 250 tons was achievable. The Saturn V rocket generated 34.5 million newtons (7.6 million pounds) of thrust.
