underdrive pulleys - Page 2

blueneonman1 · 05-29-2002, 01:42 PM

I have FMS blue pullies. Love the color and they did give a little gain up top, but I have had so many times when my car would die that I am seriously gonna yank the alt. pully. And I even have the 130 amp alt. that the 94-95 mustangs come with stock. Thats probably the only reason my alt. hasn't blown by now. But my voltage regualtor is shot because of this. My local speedshop sells a smaller alt. pulley which I'm gonna buy. Also, I belive on top of the already hot tendencies of the '94-95 mustangs, that the pullies are making me run hotter.

If you keep the pulleys in, other than the alt, what belt do you use.......where t get it from??

When my car was much more stock.... I ran March underdrive pulleys, with the stock alternator and two amps.

I never once had a problem with the car not starting. Sure, the lights were dimmer at night, but that was only at an idle.

Even after way more than three days. In the nicer weather I ride my motorcycle a lot and it isn't too uncommon for the stang to sit for a week at a time, but it always starts up. I also run an amp and sub in my car and never have problems, other than dim lights and weak fan at idle.

I have had the pulleys for about 3 years now and just replaced the stock (as far as I know) alternator last fall. I have had no problems with the new one either.

I ran March underdrive pulleys, with the stock alternator and two amps. I never once had a problem with the car not starting.
