A couple of comments:
Darryl's MGB is of the utmost quality in all respects, and has driven it more miles in the past couple of years than most of us drive our daily drivers - of any type. At the shows we've been at together Darryl has taken first place and I second, or vice-versa.
Darryl's a new member, invited by me to join the forum. I'm astonished, and frankly embarrassed by some of the responses I've read here.
He mentioned the reasons for the alternator on his website, and here. To emphasize something he mentioned: the alternator he's employing will provide around 55amps@2000rpm, 50amps@2000rpm for the 96amp build (compared to 14amps@2000rpm for the 40-amp alternator). The theory, I think, is with that extra overhead you're not taxing the alternator if you run a lot of power while the engine is idling. That theory may indeed be a debatable issue, but what isn't is that the extra overhead certainly isn't hurting anything.
Want to talk about high amperage? Take a look at the battery in your car. An Exide-72 group-24 battery is capable of producing 835 amps for 30 seconds at or above the freezing point. I haven't seen anyone complain about the ability of the battery to burn up the car though...and why is that? Because the battery, like the alternator, will only provide the current asked of it. The various circuits in the car are protected by fuses (or circuit breakers), the source of their power is irrelevant.
So then - is the stock wiring in the car capable of supporting a continuous draw of 110-amps through a single circuit? No it isn't. I dare say it also isn't suitable to support Adam's planned stereo system. For that matter neither is the internal wiring harness in the Saturn the 110/96-amp alternator came out of. It's for that reason you should run a dedicated high amperage, protected line to your equipment from the alternator/battery positive voltage terminal(s). At that point the wiring in the car is a moot point.
Finally - is a 110aH/96aH alternator really necessary? Perhaps not, but neither is adding a V8 engine or a high power stereo system, or twin SUs, or a Webber carb, or A/C, or a Supercharger. Those options are available for those who chose to use them for their own reasons - and like the alternator are completely valid alternatives to the stock car.
