The TTE900+ is a Phase 3 hybrid turbo upgrade from TheTurboEngineers, developed for the BMW 4.4 V8 twin-turbo S63 and S63TU engines as fitted in the M5 and M6 F-series. This kit is aimed at drivers who want to combine maximum performance with strong boost build-up and controlled response.
The TTE900+ is based on the original twin-scroll turbochargers but has been completely re-engineered. The original compressor is replaced by a much larger TTE billet compressor featuring extended tip technology. The compressor housing is CNC-machined to optimal tolerances and fitted with 76 mm CNC billet inlets for maximum air flow.
On the turbine side, the turbine housing is CNC-milled to accommodate a larger, lightweight 9-blade TTE turbine. This turbine reduces back pressure and exhaust gas temperatures, enabling higher boost levels to be safely achieved. The result is a potential output of 900+ hp whilst maintaining a surprisingly quick Spool-up for this power level.
A TTE-reinforced bearing assembly replaces the original thrust bearing to ensure durability under high loads.
Balancing
To ensure maximum reliability and performance, all turbos are first low-speed balanced up to 2,800 rpm in multiple planes. The complete CHRA is then high-speed VSR-balanced up to 250,000 rpm on TTE’s own VSR machine. Each turbocharger is supplied with a numbered balance test result certificate.
