Yes, you can increase your alternators overall output as well as increase power output at engine idle speeds.
Check the size of the pulley on your alternator. If you are having problems with overall alternator output or charging at engine idle, maybe a smaller pulley is all you need. The most common pulleys on GM, Ford and Daimlier/Chrysler vehicles are the 6-groove 2-7/16, 2-3/8 and 2-1/4 inch pulleys, by reducing the pulley size to 2" or 1-7/8" your alternator will start producing power sooner and produce more power cruising down the boulevard or on the highway. Also, because your alternator is spinning faster the fan will move more cooling air through the alternator adding to component life, to little air flow can burn up an alternator.

?Will this help ?
?What is the point of loss due to over speed?
Oil Pan ?what do you anticipate the %gain in efficiency to be?

Watch out for voltage drop causing a bad voltage signal from the relocated battery . Dodge used to small a gage wire for there remote voltage regulator on the fire wall in there pick ups, result the lights flicker/pulse voltage gage bounces .
