Balancing and build quality you can trust

Each unit is balanced with extreme precision. Components are first balanced individually at low speed in multiple planes, then the assembled CHRA is dynamically fine-balanced on an in-house VSR machine at up to 250,000 rpm. This process reduces vibration, enhances longevity and improves acoustics. Every turbocharger ships with a serial-numbered balance report for complete peace of mind.

What you get

• Pair of upgraded hybrid turbochargers based on original BMW housings
• Factory electronic actuators pre-installed
• CNC-milled intake pipes and oversize intake sections with O-ring sealing
• Individual balance documentation included with each unit

Real-world results

We have installed these units for S55 customers and in our own projects, and the feedback has been superb. Faster spool than expected for the output, a broad usable powerband and rock-solid reliability when paired with quality supporting modifications and professional tuning.

Recommended supporting mods and tuning

To achieve the best results, pair this twin turbo set with appropriate fuelling, cooling, intake and exhaust upgrades, plus a custom ECU calibration. A health check on the engine and ignition system is strongly advised prior to mapping.
