And I've heard that some pulleys don't provide enough electrical charging at idle

I know I'm bringing back an old thread but I'm getting ready do buy an underdrive pulley and I was wondering if it was necessary for me to buy an overdrive pulley for my alternator since I have an auto. I was also wondering what brand pulley(s) would be recommended. Thanks

The overdrive pulley isn't necessary, but if you run other accessories (radaer, system) you may want to consider it. Just keep in mind that the overdrive will decrease the HP gain you see.
I didn't need an alternator pulley either. I wouldn't worry about it unless you have a big stereo. I have a SLP ud pulley...others here speak well of the powerbond and asp.

most people with cams have their car tuned to idle over 800rpms and from what i have heard, under 700 or 800 rpms is when you dont get a good charge from an underdrive pulley, but if you are idling over 800 rpms, you would be charging just fine. i cant remember where i heard this, may have been on a previous discussion here, but i know a few people with them and they have not had any problems. i bought a powerbond 25% underdrive pulley for my new motor and it is a very nice piece of work. i got it from TSP for like $195 plus shipping? something like that.
