High Output 175A 300 Series Alternator (regulated) to replace all air cooled Porsche 911 alternators.
This alternator fits the original fan housings.

Fits:
Porsche 911 up to 1973

For cars up to 1973 the alternator is a direct fit.

300 Series WOSP Alternators
The WOSP 300 Series represents our latest-generation alternator technology, designed for maximum efficiency and performance. These advanced units use square wire ‘hairpin’ (segment conductor) stators, delivering exceptional current density and allowing much higher output compared to traditional designs.

Each alternator case is precision-machined in-house from billet aluminium, ensuring strength, durability, and a perfect fit. The result is a range of plug-and-play alternators built to outperform standard OEM units while maintaining easy installation.

Key Features
• Advanced hairpin stator technology for superior efficiency
• Precision billet housings manufactured in the UK
• Wide range of direct-fit, plug-and-play applications

Upgrade your classic vehicle’s charging system without compromising its period-correct appearance, with Wosp’s Dynator – a high-performance 6 or 12V alternator cleverly disguised as a traditional dynamo or generator. 

Designed and manufactured in-house in the United Kingdom from billet, these units deliver approximately double the output of the original dynamo they replace, while offering greater efficiency and weighing just 60% (approx.) as much.

Fits:
Porsche 912 1965-68
Porsche 356 B 1.6L 1960-63
Porsche 356 C 1.6L 1964-65

Fitment Information: 
The diameter of this unit is slightly larger than that of the original dynamo (90mm), meaning the cradle it mounts on will need to be machined to accommodate the increased size. 

These internally regulated units are direct replacements for the original dynamo. You simply have to bypass your regulator box or replace it with one of our dummy bulkhead mounted regulator boxes to eliminate any wiring modifications.

-Specifications-
Voltage: 6V or 12V
Amperage: 50A
Polarity: Positive or Negative Earth (Please Select Below)
B+ Terminal Position: Fixed
Pulley: Uses Original Pulley
Build Standard: Manufactured to BSI ISO 9002

All of our units are built to the highest standards using only O.E. parts and units. 

Complementary to our starter motors we also produce a complete range of alternators varying in outputs, fitments, size and more. Whether it is a new high quality Lucas replacement or an upgraded lightweight CNC billet plug & play unit there’s usually multiple options. Additionally, growing in awareness our dynators which are alternators disguised as dynamos for the classic car market. Built to be the most authentic looking and reliable on the market they now produce over 200 different models.
