You either need a larger crank pulley, or smaller water pump and alternator pulleys.

Doh! Of course, you're right Paul, thanks.
I have a big cfm Kenlowe puller fan, with two speeds. When on "boost" it is pulling the battery down, but not if I just raise the revs a bit. Having said that, it is only on boost when the front fans are already running. So I think a bigger crank pulley will do both jobs. I'll have a hunt around for one.
