To calculate the alternator shaft speed, which should be no more than 16,000 RPM do the following:

Alternator pulley size (ie 2.5")

Crankshaft Pulley Size (ie 5")

Ratio is 2:1 (5 / 2.5 = 2)

Max engine Speed = 5800 RPM

Multiply Max RPM x Ratio (5800 x 2) = 11,600 shaft RPM Max

Idle RPM = 1000

Multiply Idle RPM x Ratio (1000 x 2) = 2000 shaft RPM @ Idle

 

An alternator needs 1800-2000 at idle to make power and will make maximum output at 6000 rpm, and will start to fail at 16,000 RPM.
