I was wondering what kind of pulleys would give me the most hp out of it but still not have problems with my alt. charging my battery b/c of my system.
You can go with a 25% underdrive crank pulley, but some companies sell and additional alternator pulley as well.
I haven't done this, but I'd be reluctant to get the alternator pulley with the crank, especially if you run a high powered stereo system. Then again, a giant capacitor might help here also.
