200 AMP Alternator

This is a very popular replacement where significantly increased capacity is needed. This alternator is more popular for highly electrically modified cars - this unit will increase the charging capacity significantly at all RPM Ranges with no modifications.

  • ·This unit is a direct replacement
  • ·100+ amps at idle (2000 alternator shaft rpm)
  • ·200+ amps maximum (6000 alternator shaft rpm)
  • ·The stock belt can be used on original equipment vehicles
  • ·Actual Alternator Weight is 16.4 lbs
  • ·All units are 100% NEW and come complete with internal voltage regulator and pulley
  • ·All alternators are 100% new, tested at time of assembly

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.
