Product Description
The WOSP 300 Series Super Efficient High Output Race Alternator delivers consistent electrical power output at low engine speeds for vehicles with high electrical demand. Built around the latest generation Denso platform, it uses specially designed windings to deliver high charge rates from idle, supporting the performance of key systems like electric power steering, heated screens, and cooling fans.Explore the key technical features and how they support reliable, efficient performance across varied applications:Latest Generation Denso Base Unit: Engineered using advanced Denso technology, this unit is compact and lightweight while maintaining durability, allowing for a superior power-to-weight ratio that reduces strain on the engine and improves overall vehicle efficiency.High-Efficiency Windings: Features specially wound stators that maximise electromagnetic efficiency, enabling the alternator to deliver high charge rates at low RPM which supports critical systems during idling or low-speed operation.Idle-Speed Charging Capability: Produces up to 80% of its rated output at engine idle, significantly reducing voltage drop and supporting the continuous operation of energy-intensive components during periods of low engine load.High Amp Output Range: Offered in multiple amperage ratings to match different electrical load requirements, ensuring compatibility with varying setups and preventing underperformance or overcharging.Lightweight Aluminium Casing: Built with a robust aluminium housing to minimise weight while providing sufficient heat dissipation, aiding thermal control and supporting long-term reliability in high-demand setups.Included Pulley System: Supplied with a pulley that matches standard belt arrangements, simplifying installation and allowing quick replacement or setup changes without additional parts.Optional Pulley Configurations: Designed to accommodate interchangeable pulleys available separately, enabling customisation for different belt layouts or specific performance setups.Ideally suited to both competition or road use these high-output alternators deliver strong performance at low RPM, helping to maintain voltage stability during typical operating conditions where demand is high but engine speed is low. The compact, lightweight construction makes it a smart choice for maintaining power delivery while keeping engine load and space usage to a minimum. This alternator is a valuable addition to your car setup, particularly where reliable low-speed charging is essential for consistent electrical system performance.Fitment info:Millington Diamond Series 1 & 2
