The Relentless BMW E92 M3: Supercharged & Six-Speed

A 2009 BMW E92 M3 that brings a six-speed manual, supercharged performance and factory engine management together in the Relentless Motorsports TX project lineup.

A DRIVER-FOCUSED FOUNDATION

This M3 starts with a lightly optioned configuration and no iDrive. Its six-speed manual transmission keeps the driving experience central to the build.

SUPERCHARGED PERFORMANCE

The car produces approximately 700 horsepower with an Active Autowerke Stage 3 supercharger system and water-methanol injection. Engine tuning is handled through the original DME, retaining the factory engine-management platform.

CHASSIS & FITMENT

KW V3 coilovers lower the car and form the foundation of its suspension setup, complemented by aftermarket wheels.

THE ELECTRONICS CONNECTION

For Relentless Motorsports TX, this project connects an enthusiasm for performance cars with a focus on automotive electronics. The M3 pairs substantial mechanical upgrades with tuning on the factory DME—an important part of the overall build story.
