Pulleys with Stock motor

[DFG 5OH]

Does anyone have underdrive pulleys on a completly stock motor, and if so, do you guys have any cooling problems, or any low alternater voltage problems?

Thanks

it will drop your voltage a bit at idle but not enough to worry about if you dont have a large stereo.

Will not using the alternator pulley prevent that?

Yes, it will, but you'll have to buy a slightly shorter belt if you do. Using a 4-cyl Mustang alternator pulley is a good alternative. It kind of falls between the large one supplied in the kit and the small stock one and allows you to keep your stock belt.

On a side note.....although the pulleys did make my guage drop, I never once ended up with a dead battery. I’ve also got power everything, a booming stereo system and electric fan on my car and have no problems with charging or cooling. You guys with the factory 130A alternator have it better still. Us fox guys used to have to put up with a crappy 75A unit.

I had alternator pulleys on my almost stock car, now there just sitting in my garage if anyone wants them

i have them on my car without the u/d alt pulley and the stock belt works fine, no cooling issues
