The compelling evidence for a connection between SS 433 and W50 has provoked much imagination for decades. There are still many unanswered questions: What was the nature of the progenitor of the compact object in SS 433? What causes the evident re-collimation in SS 433’s jets? How recent is SS 433’s current precession state? What mass and energy contributions from a possible supernova explosion are required to produce W50?   We have developed detailed hydrodynamic models to confront these questions,  which are implemented using FLASH with AMR.

I will talk about a few of these hydrodynamic models with some interesting results featuring the supernova dynamics alone, and the SNR combined with a simple jet model.
