We present high spectral resolution, high signal-to-noise Very Large Telescope (VLT) data of the QSO SDSSJ0318-0600 (z=1.967), along with the measured quantities pertaining to the outflow absorption seen in both high and low ionization species. SDSSJ0318-0600 shows an array of 11 separable kinematic components in blueshifted absorption spanning a velocity range of -2800 to -7500 km/s. Our column density analysis provides ratios to determine electron densities, total hydrogen column densities, and distances for three of the components, the fastest (-7500 km/s), slowest (-2800 km/s) and strongest (-4200 km/s) components of the outflows. Provided these quantities for the absorber with the largest hydrogen column density, we find kinetic luminosity, mass flux, and abundances. These results provide an example of an AGN wind that could account for enough energy to suppress cooling flows in clusters, supply enough metals to account for a small fraction of ICM metallicity, and affect the rate of super massive black hole growth.
