MECHMAN | 320 AMP H.O. ALTERNATOR FOR LEXUS

S Series
The S series of 6 phase alternators offers incredible output in a compact and durable package. Highly efficient, these units use less horsepower per Kw produced than conventional 3 phase alternators. 12 diodes, twinfullcopperrectifier plates and outstanding airflow ensure long service life, even in severe conditions. The 240-amp model offers the best balance between peak output, and output at engine idle RPM.

Installation Notes:
1. This unit comes equipped with a smaller 1.75-inch diameter alternator pulley and will require a slightly shorter drive belt to be installed for proper belt tension.
2. While this 320-amp alternator does make more power than our 240-amp offering, in some applications it may cause a low to no voltage output at idle. We always recommend our 240-amp version for 95% of customers.
3. If your vehicle does have a low or stock idle (400-600rpms), the 240 amp version is most likely your better option. If you do not mind moving your idle up <200 rpms> or so or can rev the vehicle up while stopped the 320 create more power. It all comes down to personal preference for the customers application.
