: Alternator upgrade, 12SI enough?

Well it's time to kiss my old alternator and external voltage regulator goodbye. From the research I've done it looks like a 12SI would bolt up and give me 94 amps. Here's a list of accessories I plan on running:

MSD w/ 6AL box
Electric cooling fans (28 amps)
Fuel pump
Vacuum pump (for my brakes)
Plus normal stuff like lights, horn, etc.
Radio is disconnected and will most likely never be reconnected.

So the big question is 94 amps enough or should I consider a cs130? What kind of headaches is there going to be with the cs130?
Thanks!

94 amps is plenty, make sure you get a decent 13 plate or bigger battery as well

I have an Optima red battery, not sure how many plates. It is about 5 years old.
