Hi volume oil pump vs standard volume pump
I can tell the difference on a cold engine pre-oiling with my cordless drill. Plus there were enough breakages or concerned over it that Mopar developed the heavier drive shaft for them. So yes, there will be power taken by the pump and to probably similar extent, the additional windage created by excessive oil draining back and flying off parts. Just my observations on the subject. I'm not going to worry about quantifying beyond that.
