BMW TTE550 N55 UPGRADE TURBOCHARGER
The TTE550 for the N55 motor. Still keeping the original turbocharger the compressor wheel is exchanged for a TTE milled aluminum wheel with state-of-the-art geometry, 7+7 blade so producing extra power. Equally, we change the original exhaust turbine for a far larger but very lightweight 9 blade TTE designed the turbine for lower exhaust gas backpressure giving greater performance, yet still giving a good spool response.
We also fitted a TTE motorsport upgrade bearing system for durability.
Equilibrium
Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on the application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial numbered balance test result document.
Please note if sending a used turbocharger for the upgrade process. TTE does not test or recondition the Electronic actuator you send. Your sent actuator will be re-installed
