Mechman S Series Alternators

The S series family of alternators offers large case alternator performance in a compact package. Highly efficient, these 6 phase alternators use less horsepower per Kilowatt than conventional 3 phase alternators. 12 press fit diodes, twin rectifier plates, and highly efficient twin internal cooling fans make them durable in any application. Smaller, lighter rotors and reduced rotating resistance make them an excellent choice for high RPM or racing applications. Like their big brothers in the Elite series, the S series have hairpin stators and high pole count rotors that create much less Electromagnetic noise than conventional 3 phase alternators.

General Features:

  • 240 amp alternator
  • For use with select 2005-2009 Acura vehicles
  • Cast aluminum construction
  • Cutting edge 6 phase hairpin epoxy reinforced stator technology
    • Improves durability
    • Increases high RPM stability
  • Oversized charge post ensure sturdy cable connections
  • Premium low-drag bearings
  • Ultra precision balanced rotor
    • Provides 20,000 RPM capability
  • Twin solid copper rectifiers with 12 press fit high amp diodes to spread out heat
  • 15% more efficient than typical alternators
    • Wastes less horsepower in the form of heat
  • Precision pulley machined from bar stock
  • Authorized Internet Dealer
  • 2 Year Manufacturer's Warranty

Worth it!!

August 26, 2016

Is it a bit pricey? Yes. But anyone who is serious about their car audio knows the value of upgrading from the stock alternator. I've had two different mechman alternators now. One was in my mustang that got totaled over a year ago and now this one. Worth it in many different ways. With this alternator, I've never had the lights dim, or amps suddenely cut out or go into protect mode from power loss. These alternators are made very well and I personally have never had a single issue with either one that I've owned. Do yourself a favor and get one. You wont regret it! I'm currently running a Hifonics 1200 watt and a Pioneer 800 watt 5 channel. Both true RMS. Looking to upgrade my mono amp in the future to around 2000-2500 watts. It's great to know that pretty much whatever I put in here, this alternator can handle it with ease. Save your money, get a mechman.
