Over 400+ amps at 1800rpm and 230+ amps at 650rpm (under full load). 

Denso Hairpin Design for maximum Performance. *All our Competitions Series (CS) Alternators are supplied with the largest Dual Bridge Rectifier available in the marketplace. **OEM Bearings supplied on all our units **Highest rated Voltage Regulators in the industry.

AutoTech Engineering alternators need a minimum of 650rpm to charge.

Unless otherwise quoted or instructed, our units come with the OEM voltage output for plug-and-play alternators. The quoted voltage settings are already built into the alternator's voltage regulator. Remember that in PCM- and ECU-controlled vehicles, the vehicle's “brain/computer” controls the voltage.

Boosted Harness Option
A boosted harness option is available at an additional cost. If you select this option, your harness will arrive with the diode already installed. You can choose 15.3, 15.5, or 15.7 volts.

What is a Bypass?
If you choose to have a bypass, you are wiring around the PCM or ECU voltage control. This allows us to customize the charging voltage beyond what the vehicle’s computer normally permits. In most cases, the battery warning light will remain illuminated.

Bypass charging voltage: 14.8V.

Important: A PCM/ECU bypass is required when using the boosted harness.
