higher output alternator vs smaller pulley

[OzCharger69]

Hello all,

I have a Powermaster 95A alternator in the Charger. The Charger is very electron hungry with Classic Air A/C, twin SPAL 4000cfm fans, decent radio, dakota digital gauges etc etc. While driving around, the alternator keeps up quite well. On a hot day with A/C and fans running, the voltage will drop to 12v at idle.

Should I be looking at a higher output alternator or keep the current one and switch to a smaller pulley?

I'm not sure what's the experience with the smaller pulley, does it burn the alternator in the long run?

Thanks for any help

If you never have problems with the battery I would keep driving and enjoy it.

As long as you don't overspeed the alternator, shouldn't be an issue with a smaller pulley.

You shouldn't run faster to gain power.
Use relays in your electrical system when available to cut down on power demand.
If you need more towing power on the highway, lower gears just make your top speed lower.

I don't think he will be doing any towing with a Charger....

As long as dropping to 12v at idle does not affect idle quality [ smoothness ], I would leave it. Also depends on ign system & components. Inductive systems such as points, Chrys elec, HEI are voltage sensitive. CD igns such as MSD 6 will work with 8v.

As far I know, the PowerMaster 95 amps units come already with the small stock pulley made for our cars. Can’t recall the diameters thought. They are able to put around 65 amps at idle.

Relays don’t cut the power demand. They just bypass in most of cases original power route or work as a switch. The power demand is allways the same since is a DEMAND from the accesories
