There may be a slight misunderstanding there - I'm not questioning the alternator's ability to deliver the goods - if you care to measure the alternator output yourself, you will discover that even when turning at 3500 rpm, the output will be significantly less than 100A, because the actual output is going to be determined by the load and the voltage regulator, rather than what the alternator is capable of delivering.
The alternator output is typically highest for a brief period directly after the engine has been started, which coincides with the recharging of the battery to replenish the energy used to crank the engine.
With stock electricals, once the battery has been recharged, the alternator output will drop to - I would estimate - 6~8A during the daytime, it'll be somewhat higher at night, when the lights are on - depending on accessories, radio/stero, a/c, etc., it could be higher.
The simple truth is a stock Samurai rarely does need more than around 50A.
Now - let's talk about that "dual ribbed main pulley" - what exactly do you have in mind? A dual crank pulley? A dual crank pulley with multiple ribs?
Such things do exist and can be sourced from other Suzukis - a 1.3 Swift with a/c will have such a pulley (3 rib belts if my memory serves correctly), a 1.3 Baleno with a/c will have one with 4 rib belts, again if my memory is good - you will of course need to change the water pump pulley to match.
