We present a study of X-ray versus Sunyaev-Zel'dovich Effect (SZE) scaling relations for a sample of 36 high redshift (0.14 < z < 0.89) galaxy clusters with both Chandra X-ray data and BIMA and OVRO SZE data. We compare integrated SZE flux with X-ray derived gas mass, spectroscopic temperature, and total mass to determine how firmly connections between the SZE observable and derived cluster properties can be established in upcoming SZE surveys. We show that the integrated SZE flux and X-ray derived properties exhibit tight scaling relations over the full range of redshifts when cluster cores are excluded from the X-ray data, although no such exclusion is needed for the SZE data. This talk will review the methodology involved in constructing these scaling relations and present our results and their implications.
