TTE Audi 2.7T Turbocharger Upgrade TTE780+ (B5 S4/RS4 & C5 RS6/A6 Allroad)
TTE780+ Turbochargers start life as Genuine RS6 K04 OE units. Engineered and enhanced using in most part BorgWarner components or better. These units offer the next step to increasing your 2.7T motor performance, yet offer relative little loss in response for such huge power potentail. Offering a balance of high power and fast response. Making around 2.0bar at 4k rpm on a 2.7 motor with right hardware and tuning.
Precisely balanced 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, 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 TTE's 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.

Note: These turbochargers use K04 RS4 B5 compressor housings with 58mm inlets. Specific turbo intake pipes to suit are required . The turbine housings are RS6 C5 specific, so flange on downpipe is needed to match. They do not work with RS4 B5 specific downpipes but these can be adapted with use of a RS6 flange.
