Why choose the TTE460 N55 hybrid turbo
TTE starts with a new OEM N55 turbocharger, dismantles it and upgrades the core components to increase flow, reduce back pressure and improve efficiency. The result is a bolt-on BMW N55 turbocharger upgrade that retains factory fitment while supporting serious power on 98 RON fuel.
- Highly efficient next-generation TTE billet compressor wheel for big flow and fast response
- Re-profiled and machined compressor cover with optimised tolerances for maximum efficiency
- Enlarged, ported intake pipe for smoother incoming airflow
- Special curved clipped turbine and shaft to reduce back pressure and keep EGTs lower
- Reduced rotating mass for improved spool and transient response
- Genuine actuator and genuine diverter valve
- OEM fitment, plug-and-play installation on the N55 platform
- Dynamically balanced up to 250,000 RPM with individual serial-numbered test documentation
- Designed, machined and built by TheTurboEngineers in Germany
- 470+ PS capable on 98 RON (fuel quality, hardware and calibration dependent)
Engineering and balancing
Precision balancing is critical for turbo longevity, acoustics and performance. TTE balances individual parts up to 2,800 RPM, then dynamically balances the assembled CHRA at up to 250,000 RPM using in-house VSR equipment. Every turbo is supplied with a serial-numbered balance report.
