Description

Note: The TTE550 has been discontinued due to the release of TTE600.

TTE550 begins as a brand new standard N54 turbochargers that we dismantle and then set about upgrading and optimizing as engineers to create our ultimate hybrids. TTE550 Turbochargers offer great power and spool for the range of N54 vehicles.


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 optimized tolerance to ensure maximum compressor efficiency. The intake pipe is larger and ported to give a smooth transition for the incoming air flow.

A key part to driving the large TTE compressor and in turn making this unit produce the huge power advantage over stock  is machining and fitting a far larger curved clipped turbine and shaft, while still keeping the original core. This turbine gives much lower back pressure and keeps EGT lower compared to stock turbine or clipped stock.

The clipping of the turbine. Clipping reduces blade area thus increasing gas flow and so reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost level's. This process gives a secondary advantage of removing some material, lightening the turbine thus reducing rotational mass improving moment of inertia.

We re-engineer the rattle prone waste gate flapper for a more robust design for trouble free operation.

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 the CHRA is 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.

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.

 

TheTurboEngineers(TTE)
TheTurboEngineers GmbH based in German is a dynamic and highly innovative turbocharger engineering company, specialised in production of motorsport turbochargers to the highest quality and greatest efficiency with attention to detail. Every component is optimised on long term reliability.

TTE are focused on the construction of prototypes from a concept, through to completion with all work mostly being done in-house to TTE's extremely high standards in Germany. TTE is a fine example of German engineering at its best. 

Small details are important to TTE, as is the conversion of existing OE turbochargers to new upgrade specifications, be it new or from a supplied used turbocharger.
TheTurboEngineers GmbH consults and provides to race teams and many well known tuning houses, looking for the best engineered performance turbochargers available.
