The TTE300 upgrade turbo has been developed for the MINI R56 and offers a perfect balance between performance, responsiveness and OEM reliability. With the right hardware and software, this turbo has been proven to deliver 300+ pk on 98 RON, whilst retaining a genuine OEM+ driving experience.
The basis of the TTE300 is a brand-new, genuine BorgWarner twin-scroll turbocharger, which is completely dismantled and rebuilt by TheTurboEngineers. The turbo is fitted with a much larger TTE billet compressor wheel featuring Extended Tip Technology, which ensures a very broad compressor map and exceptionally high flow for its size, without compromising on responsiveness.
The compressor housing is CNC-reprofiled in-house to ensure optimal tolerances and maximum efficiency. The compressor inlet is also CNC-milled to reduce turbulence and increase air velocity. On the outlet side, a larger 9-blade high-flow turbine is fitted, with a modified turbine housing for higher flow and lower back pressure.
To ensure durability under higher loads, TTE uses a 360° BorgWarner Motorsport journal bearing, combined with a spring-loaded original BorgWarner actuator. Installation is plug-and-play, but software recalibration is mandatory.
Each turbo is multi-balanced to TTE standards, including high-speed VSR balancing up to 250,000 rpm, and supplied with a numbered balance test report.
