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 2004-2010 Scion/Toyota vehicles
  • Cast aluminum construction

Mechman overdelivers

March 29, 2017

Since installing this in my Scion TC, my voltage has never sagged below 14, even with over 1500W RMS between two amps (about 200 Amp Load) I ordered the abvm II as well thinking I would need to crank it during heavy loads at idle. Alternator doesn't even flinch. Be sure to use good 0 gauge wiring runs to make sure it can breathe.

I wanted a good high output alternator for my car and heard Mechman was one of the best.
Stanley Furman J on Nov 22, 2016
I've been shopping with sonic electronics for years and they are a business i trust so i went ahead and ordered this alternator because my stock one is not strong enough to push my sound system in my scion tc

would this fit a 1993 Toyota camry? im trying to upgrade my audio system but finding a good high output alternator is impossible for my car lol

Best Answer: Hello,

This will only fit 2004 - 2009 Camry 2.4 Liter Engine vehicles . We suggest giving Mechman technical support a call for details regarding your vehicle. They may even be able to tell you why it is difficult to find an alternator for your vehicle.
