TTE850+ Performance Upgrade Turbochargers RS6 C6 V10

The RS6 C6 with its 5.0 V10 Bi-Turbo engine and 580 PS is the most powerful Audi series production engine to date. Our TTE850+ turbochargers will push the V10 to beyond 850PS with ease. Some tuners like KSF Motorsport and MRC Tuning have seen results at over 1000PS+ making these hybrid RS6 upgrade turbochargers the biggest maybe available anywhere, yet still totally Plug & Play. Power level reserved only for true hyper cars and still remaining perfect for driving to go get your family shopping, not loosing any drivability.

Engineered & Enhanced

The formula to making a TTE850+ starts with a much larger forged milled billet compressor wheel, chosen because is highly efficient, new generation type with ultra thin blades, creating extremely high flow for comparative size, giving a compressor map that's very wide. TTE850+ Yield a maximum air flow rate of 615litres a second Vs stock of 500 (estimated). The intake pipes included with this upgrade has been CNC milled and hand finished to match and smooth the transition to the larger compressor inlet opening to lower turbulence and maximize velocity.

We also give the stock turbines a special curved clip, a grinding process to the turbine blade tips, curved to alleviate stress from process and clipping the length reduces blade area, thus increasing gas flow and so reducing back pressure, lowering exhaust gas temperatures, allowing safer higher boost level's. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing rotational mass improving moment of inertia. Dyno's have shown little to no loss in response vs stock yet huge gains in power and torque.

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.


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.

This RS6 C6 is the highest power RS6 MRC have done in the UK at 1024ps and 1203nm.
The specs:
TTE850+ Turbochargers
Sportmile Polska Uprated Gearbox
Aquamist Water Injection
MRC Downpipes
Milltek Sport Exhaust
Uprated Injectors
Uprated Fuel Pumps
MRC Carbon Clean and Deflapped Inlets
MRC Oversized Intake pipes
MRC Custom Filters
MRC Dual Flash Racefuel and 99ron Engine Maps
MRC Custom Gearbox Remap
On 99 ron this does 939ps and 1113nm.
On Racefuel it does 1024ps and 1203nm
There will be more to come on the MRC 1k kit in the future.

Ersin Yesilyurt RS6 TTE850 MRC KSF tuned vbox data was shared tonight so i could validate and correct.

100-200 best verified on racelogic website and then corrected to 5.31 Sec !
Great reason to not 100% trust vbox screen as was 5.5
Placed number 2 on the 100-200 board !

Fantastic constant power/times as shown. I have maybe 15+ runs from Ersin all in 5-6 sec zone. Ive not yet seen that before

Hi there. I have an RS6 with milltek and a revo tune running on 1o2 fuel. The car is very strong. Im considering doing some further you have an idea of how much power the stock internals and gearbox can handle?
