We develop a framework to compute the redshift space power spectrum (PS), with kernels beyond Einstein-de Sitter (EdS), that can be applied to a wide variety of generalized cosmologies.

We find that all of our models fare well on scales larger than about two to three times the non-linear scale, but fail as the non-linear scale is approached.
