i had pulleys before and they slowed my 130 amp alternator down enough to drain my battery in a week, no ridiculous stereo equipment. However, I got a brand called hauffman (maybe cauffman, maybe something else similar), but at any rate, they crankshaft pulley was held on by only the harmonic dampner bolt. Pulleys with this design are too small, but it's my understanding that if they use the 4 holes in the harmonic dampner (IE, bigger) they should work and not give you any problems.
