Currently I have a 1.5:1 ratio on my alternator - meaning it's only doing 1350 when the engine is idling at around 900k. My alternator, even when energised doesn't put much into my battery at tickover - it only climbs to 14 volts at around 2000 rpm plus. This means I'm running flat most of the time and get misfires under load.
My water pump is 0.7:1 ratio at the moment, which shoudl be mroe like 1:1. My car runs hot..
Anyhow I wonder if you could tell me anything I need to know anout sourcing pulleys - my main concern is that the all line up! I gather there are several variants of the water pump so here is mine for any identification.

And here are my pulleys removed:

My pulley diameters currently are:
Alt 75 (has a 15mm shaft with a keyway)
Water 145
Crank 108
I have all teh other dims too if needed.
Really I'm looking for guidance on getting new ones.
