Underdrive pulley's electrical performance

[Lito]

I had posted this in another thread that got sideways and is now a fight between who has the largest bolt, or stud or whatever... So I ask it here in it's own thread. Sorry if it's anything wrong with it.

Talking about pullies, I had a set on my old 92 5.0L, they came with the alternator pulley too. On those cars alt output on idle was very poor. Being that these cars are more power hungry than those but also carrying bigger alternators, this kit does not come with alt pulley but with a bigger crank pulley all accessories will spin slower than without it, my question is:

How does it feel the power output of the alt on idle with the pulleys installed, this a very car crowded city and even I don't use the car too much I would want to keep the car with its A/C, shaker 500, lights and wipers on running well while stuck in a rainy night in traffic. (something than can happen very frequently down here)

Thanks for you input in advance.

no problems with your own thread, good choice to get answers for your question.

underdrives are great on these cars. The problems with the Fox cars were due to the small 85 amp alternator. I had pulleys on my 87 LX, and the charging output was low till I upgraded to a 170-amp alternator. After that upgrade, everything was fine.

I don't know the exact spec on the alternators in these S197 cars, but it puts out plenty of juice. I've had pulleys on my 06 GT for over 20,000 miles now with ZERO problems.

Thanks Pro Mod.

Thats what I thought but just wanted to ask to be sure.

I want to keep a good driveability on this new ride.
