Part of WOSP's advanced 300 Series, it combines modern hairpin winding technology with a precision-machined billet aluminium housing, delivering exceptional electrical output from a compact, lightweight unit.
What Does It Do?
The alternator generates electricity while the engine is running, powering the vehicle's electrical systems and maintaining battery charge.
The WOSP LMA370-HO provides up to 320 amps of rated electrical output, offering significantly greater charging capacity than conventional alternators.
This makes it particularly useful for modified Porsche vehicles with increased electrical demands.
Why Upgrade to a 320A Alternator?
Standard alternators are designed around the electrical requirements of the original vehicle.
Modified Porsche engines and vehicles fitted with additional electrical equipment may require substantially more charging capacity.
The WOSP 320A alternator is particularly suitable for
applications involving:
- High-performance electric cooling fans
- Upgraded lighting systems
- Powerful audio equipment
- Motorsport electronics and data logging
- Additional electrical accessories
- High-demand electrical systems
Its increased output capacity helps support these accessories while maintaining battery charging during operation.
Advanced Hairpin Winding Technology
What makes the WOSP LMA370-HO special is its advanced 300 Series alternator construction.
Unlike conventional alternators using round copper wire, WOSP uses square-wire hairpin stator windings.
This technology allows more copper to be packed into the stator, increasing current density and enabling substantially higher electrical output within a compact housing.
The high-output version uses an uprated winding configuration to achieve its 320A maximum rating.
Precision Billet Aluminium Construction
The alternator housing is precision-machined from billet aluminium rather than using a conventional cast housing.
This provides a strong, compact construction designed to accommodate the advanced high-output electrical components.
Weighing approximately 5.3kg, the LMA370-HO combines high electrical capacity with a compact design suitable for selected Porsche installations.
Important High-Output Considerations
The LMA370-HO is designed to achieve its maximum output at higher alternator speeds.
Unlike some standard-output alternatives, high-output WOSP units require increased RPM to reach their rated charging capacity and may produce less current at idle.
The vehicle's charging cables, electrical connections, fusing and belt drive must also be suitable for the increased output.
For standard Porsche vehicles without additional electrical equipment, a lower-output WOSP alternator may be more appropriate.
When Should It Be Replaced or Upgraded?
Consider upgrading when:
- The existing alternator cannot support increased electrical demand
- Additional electrical accessories are being installed
- Battery charging becomes inadequate under heavy electrical load
- Building a modified road, track or competition Porsche
- Replacing a failed alternator with a higher-capacity alternative
Confirm the cause of charging problems before replacement, as wiring faults, battery condition and belt issues can produce similar symptoms.
