Had to take my car to a shop to fix my harmonic balancer, because i didn't have any of the right tools for the job. While its there i asked them to pt my bbk underdrive pullies on, the belt ripped so i need a new belt but do i need a bigger one for the underdrive pulleys?

Holy ****, you haven't instlled those yet? LoL I sold those to you about a year ago! Get those things on

I HATE my u/d pullies, for all the undervolt problems you have at idle with
those things they are not worth the 3-4hp you get.

I just took mine off.

Mine ran fine with the pulleys. I only took them off because I had to when I got the supercharger. I even had a 560w (RMS, not Peak) sound system hooked up to it. Of course, I also had a 1.2 farad capicator to help with the load from the stereo. But it was still okay

it sucked cause at stop lights the headligths would dim, had to keep the radio turned down overall it sucked

I don't even have underdrive pullies on my fox and when I turn on the a/c, electric fan, headlights and barely run my stereo, my lights get dim as hell, and thats with a 2 month old 200 amp alternator. I still can't understand what the hell is going on with my charging system.

No problems here (my '83 GLX) with underdrive pulleys and 3G alt. I get full voltage at idle even with a relocated battery and electric fan.
