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 back pressure giving greater performance, yet still giving a good spool response.

We also fitted a TTE motorsport upgrade bearing system for durability.

Picture is for illustration only, the actual product may differ from the images.

Engineered & Enhanced
The formula to making a TTE550 starts with a much larger TTE billet compressor wheel, chosen because is highly efficient, new generation type with very thin blades, creating extremely high flow for comparative size, giving a compressor map that's very wide. The Re-Profiled compressor cover is machined to a optimised tolerance to ensure maximum compressor efficiency. Also the intake pipe is larger and ported to give a smooth transition for the incoming air flow.

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 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 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.

Upgrade your Existing Turbo
To upgrade your existing turbo, you will need to send us your non-damaged turbo. The listing price is the cost of upgrading a non-damaged turbo only. If your turbo is damaged, there may be extra cost on top of the listing price, we will provide you with a quote after inspection. All turbo will be closely inspected before the upgrade is carried out. You will also receive a report from our engineer after the upgrade is completed.
