So, even deleting or smoothing the pump impeller would not save us ...... the precious item is the tbelt and its driven components. Therefore we would need to replace the pump with a flat piece of stock that holds a very strong, very well-mounted stud akin to the stud or boss on the idler. I think the design of the pump, coupled with the stresses and slaps of a timing belt, may just be too much.

For those concerned about power loss, maybe the answer would be a shaved impeller for applications where high RPMs are the norm. An electric pump would take up the slack while sitting on the starting grid or in the pits. For a daily driver I would think it's best to leave well enough alone except to make the unit generally more robust.
