TTE950+ RS4, S4 B5 Upgrade Turbochargers

TTE950+ Big power solution for the AUDI 2.7T V6 Powerplant aimed and designed for the power elite B5 owners like Philipp Kaess with the infamous RS4 Limo that holds multiple records for the B5 platform. A Huge amount of development tuning this turbo spec to create ultimate high power with good boost response.

Engineered & Enhanced

TTE950+ Turbochargers are based on Genuine BorgWarner Porsche K16 turbine housings and cores with Genuine BorgWarner compressor covers with TTE billet anti-surge inlets.

TTE CNC machine in-house the Genuine BorgWarner compressor cover to allow fitment and maintain the efficiency of a larger highly advanced billet milled 7+7 blade high-pressure compressor wheel and for fitting the TTE billet Anti-surge 63.5mm inlets.

The Compressor wheel is a TTE 7 blade billet milled high-pressure anti-surge geometry compressor wheel, features promote greater airflow and pressure using a low inertia wheel that performs like a wheel of even greater size and mass. 7+7 Blade technology enables lower boost threshold giving the user faster spool-up at lower engine speeds while providing the high boost with much less heat for powerful top-end performance.

The exhaust turbine housings are CNC milled in-house to allow fitment of the large 9 blade turbine to an optimum clearance for maximum efficiency. We also modify exhaust entry port from a stock size diameter, increasing the size of the throat to increase the flow capacity before the turbine and perform other modifications after the turbine for increased performance.

motorsport 360 deg journal bearing system are fitted, to remain durable at higher loads with no loss in transient response.

Actuators used are uprated sprung OE units fitted with our reinforced clamps for trouble free operation. These also can also be modified/set to customer needs and specifications. These are supplied in kit form to allow the end user to custom fit as required.


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.

TUNETEC PROJECT 1 xxx ps complete!

THE VEHICLE GOT 2 mappings during the trip switchable:
1 Level 857 PS / 978 NM LD 2,1 @ 1,9 bar
2 Level 1013 PS / 1156 NM LD 2,6 @ 2,4 bar

Engine design and software by TUNETEC , mechanical implementation took place by my werkstattpartner Bernhard Reitsamer e.U., at this point again my sincere thanks for the implementation and completion of the vehicle after a long odyssey in "Just 3 weeks" - top performance berni

What is it about this engine that allows it to generate so much higher specific power than any other engine?

What's it got that a Golf R or RS6 doesn't have?

On the face of it the ingredients aren't all that great - split pin crankshaft, no block girdle, nightmare inlet and exhaust plumbing.... Could it simply be that the inlet & exhaust manifolds have enough room to flow well?
