Alternator Denso XS Race 115Amp Bosch 102mm

The POWERMASTER Alternator Denso XS Race 115Amp Bosch 102mm (SKU PWM8128) is a compact, high-output racing alternator built to deliver consistent electrical power in demanding engine bay environments. Engineered with a Denso-style design and rated for 115 amps of continuous output across 12-16V systems, this unit replaces stock alternators in performance and racing applications where electrical demand exceeds OEM capability.

The 102mm Bosch-mount configuration with saddle mounting bracket integrates into existing engine installations with minimal modification. Its aluminum case with black powder-coat finish resists corrosion and heat degradation, critical factors in high-RPM environments where underhood temperatures exceed standard driving conditions. The 1-wire connection simplifies wiring and reduces parasitic drag compared to multi-wire alternator designs. At 7.4 lbs, the compact XS-series profile minimizes weight while maintaining robust internal construction, making it ideal for vehicles where alternator placement is space-constrained or where every pound matters for performance.

This alternator is purpose-built for street rods, race cars, engine swaps, and restorations requiring reliable 115-amp output without sacrificing underhood aesthetics or space. Racing enthusiasts, fabricators, and engine builders select the POWERMASTER XS-series race alternator when OEM units lack sufficient amperage for custom electrical systems—including high-demand ignition systems, fuel injection controllers, cooling fans, and auxiliary lighting. The Denso-style architecture ensures compatibility with common engine mounting schemes across domestic and imported platforms.
