Here, we present numerical evidence for robust superconductivity in a triangular Hubbard-Hofstadter model at $\\pi/2$ flux per plaquette. Employing infinite density matrix renormalization group calculations on infinite cylinders of finite circumference, we observe superconducting ground states for a wide range of dopings, whose pair-correlations strengthen as the 2D limit is approached.
