1. A method for customizing a performance device, comprising: providing a baseline model defining modifications to a base device necessary to obtain a master device, including at least one modification calculated to improve performance of the master device over the base device; receiving at least one change to a parameter of the baseline model from a customer: responsive to the at least one changed parameter, modifying a plurality of other parameters in the baseline model to obtain a customized device having the improved performance of the master device, including modifying certain of the other parameters based on information received from a community of users; providing the baseline model to the community of users, including providing metadata to the community of users, including one or more of a technical analysis, a hydrodynamic flow analysis, a computational fluid dynamics analysis and a finite element analysis, wherein certain of the community of users create other customized devices from the baseline model; and generating manufacturing instructions, the instructions when executed by an automated production machine, causes the production machine to manufacture the customized device.
