An overdrive alternator pulley will help a bunch, ASP makes a nice one. I have one on my stang and my f150 and it works great. I think I paid about 25 bucks each shipped for them. I did have to use a thin wall socket to install themit because of their small diameter. Well worth it in my opinion.

too much trouble for little gains, and adding an overdrive pulley defeats the purpose of underdrive kits

Can you explain, I don't think increasing the alternator RPM's a little bit is going to kill all of the power gains from the underdrives. My car and truck both gained power from underdrives but I am not running a big stereo system either. I was just posting my own real world experience, to each there own I guess lol.

you're only freeing up a few horses, at the expense of poor charging and cooling ability

Poor charging and poor cooling resulting from underdrives means your car had a poor charging and cooling system in the first place and needs repaired anyways. I've run underdrives including alternator for 2 years with no problems.

Your right I swithced back over to my other pullye's and the car
is doing the same thing I just got this car a couple weeks ago and
I have to go through the wiring something is wrong somewhere...

Could be a bad alternator. Just take the parts to advance or another parts store and they will test it for you.
