too many amps, need better alt?

[weq92f]

Going to add electric fans which when running will draw 24 amps ( 2x12 ). Calculating my total amp draw across the entire system I find that if everything is actuating all at once my total draw would be 121 amps.

My alt is currently a CS-130 at 105AMP. So, it's pretty close at the moment to being about the right size for my system without the fans ( amp draw without fans is currently 97 if all electrics came on at once! ).

What'dya think, should I upgrade the alternator as well when I add the fans?

Here's the amp calculations just for grins:


dizzy 8
Electric cooling Fans 24 total ( 12x2 )
Headlights 15
tail led lights 2
gauges 5
Radio/Stereo 8
Atomic EFI unit w/pump 30 max: normal: 14-18 -- I calc'ed 18
MSD 6a box 6 max
electric windows 10?
electric door locks 4
electirc seats 10?
A/C blower fan 7 on high
A/C clutch 4

121 total if all is running at same time
97 without the fans added

Thanks,
