natcho, a couple of questions. what size crank pulley is the 1.9 alternator ratio based on, the 7" or 7 1/4" or other ? what size alternator pulley, the 2 3/4" or 3" ? what would you consider the ultimate alternator ratio to be ? how does this compare to the ratio's of today's 100+ amp systems, say on a minivan using a denso alternator ?
