Ed-
Racemate makes their own water pumps and pump housing castings as well, does all the design. I think you have to buy one of their pumps to get the alternator. However, don't know the long term effect of loads on the pump. I suppose the shaft and bearings are made to take the load?
Ask them on their website.....
