Normal
The only thing I can suggest is the drive to driven ratio on the pullies should be close to 2 to 1 for a positive charge/voltage output at 1,000-1,200 rpm idle. I didn't see if you listed the diameters of the pullies you're planning.1.5-1.75 to 1 is okay. It all depends if you want a positive charge/voltage output at idle. I went with a 4" crank and 2" alternator pulley for this reason.
