Smaller alternator pulley...

anyone have any luck switching to a smaller alternator pulley? Were there any noticeable gains in output?

not too worried about it. Car isn't driven daily and is always at low rpms.

Helps idle output.

I tried it on my van and had to go back to the full size pulley due to the belt slipping on the smaller pulley.
