We present our work on outflows in the Seyfert-1 AGN, NGC 4051. The joint study of both winds and jets allows us to address the total outflowing power and feedback of this AGN. Evidence for compact jet production is observed in the EVLA 8.4 GHz band, while the warm absorbing winds are observed in Chandra HETG spectra. Counter to the expectations of the fundamental plane of accretion, accretion power (traced by X-ray flux) and jet power (traced by radio flux) are only weakly correlated in our simultaneous EVLA and Chandra data, or perhaps even anti-correlated. This may represent a separate mode of disk-jet coupling that obtains at high Eddington fractions. Both XSTAR and Cloudy models for the X-ray warm absorbers require only two absorption zones. The closer of the two gives a wind launching radius of just 100 gravitational radii, perhaps suggesting a role for magnetic driving of the wind. Evidence for simultaneous jet and wind production is significantly different from stellar mass black holes. These results will be discussed in terms of wind and jet production across the black hole mass scale.
