O.K., time for some back of the envelope calcs.
* anyone know (or know how to find out) the flow requirements
of the water pump? (the pressure is not a problem here:
both ends of the pump are under same pressure. we only
need to find out how much work the pump has do against
friction)
* oil pump: depending on where the cooler is placed, it
_may_ have to fight gravity, + friction in the cooler.
anyone willing to throw some numbers out?
In all, I would imagine the oil pump to be of lesser power,
since it will only be working as an auxiliary.
a word of caution:
DO NOT UNDERESTIMATE the drain on the alternator. Even a
1/8 HP 12V pump would draw about 8 to 9 AMPS. In the 120V
world this would be .8 - .9 Amps, but unfortunately they
do not make those alternators yet :-)
