Reminder: One of the weak links in a high output alternator system are the bearings in the other items driven by the same belt/s. Many waterpumps will not take the loads involved; both the overall tension to keep the belt/s from slipping under the additional load, and the additional local tension caused by the greater hp load on the belt/s (if the pump is between the crankshaft & alternator in the direction of rotation)
