Welcome to our TTE940 Stage 3 Turbocharger upgrade for the BMW S58 Motor. 

To construct a pair of TTE940 turbos we removed the original compressors and employ a far larger and more efficient billet wheel and mill the compressor cover to the optimum gap to match the new compressor profile. We also fitted TTE 9 blade Low-Mass turbines in the turbine housings for greater flow and lower exhaust gas temperatures at high boost and designed and fitted our upgrade bearing pack for durability.  Used in Euro racing series that's including 24hr racing. 

We also supply TTE upgrade turbo inlet intakes for no restrictions and ease of use.  This combination gives the greatest power potential but also a fast boost response for the ultimate Plug & Play hybrid turbocharger upgrade.  Race tested and approved.  


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 a serial numbered balance test result document.
