Incredible...
Nobody has mentioned the HP drop when the alternator kicks in to drive those (2) electric fans..
Electric fans can draw up to 35 Amps, while many OE Mopar alternators were only rated < 50 Amps...

Just my $0.02...



HP drop was measured and factored into the dyno tests. HP drop is much less than that of a mechanical fan but yes, there is an additional load placed on the alternator from the electric fan. After all, nothing is free.

That being said an electric fan can cut off entirely when it's not needed (ZERO loss) unlike a mechanical fan.

As I already mentioned, adding electric fans will most likely necessitate upgrades to the charging circuit or you will create more problems. As for my car, I went to a 100 amp alternator and I don't have discharge unless I am idling in gear/lights on/AC on/hi blower/fans on @ the same time. This all goes back to the "well-planned" part I talked about.



I wouldn't call that "well planned" if your car discharges at idle with everything on. That's not any good.

I recently installed a 99 amp powermaster alt in my ride. Made a huge improvement and it put's out good down low. I also put my lights and AC on relays and my lights stay bright at idle now, 13.9-14.1 volts bright at idle with the new alt.
I can't stand when a car discharges at night and the headlites dim. I always kept my foot on the gas some to keep the Rs up so my headlites stayed on. No more.

I think this powermaster could handle a 30 amp fan at idle?? Don't know it might be a problem?
