TTE4XX 4C 1750 TBi Upgrade Turbocharger

TTE4XX 4C is TheTurboEngineers very latest hybrid performance upgrade turbocharger based on the Original turbocharger for the Alfa 1750 TBi turbocharged engine. Superfast spool and response with extra horsepower. We feel this is a great performing 350+HP hybrid turbo. 


Engineered & Enhanced  


To construct a TTE4XX we change the original compressor 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 change the Original exhaust turbine for a larger 9 blade high-flow item to lower EGT and raise the power potential but maintain a great boost response profile and replace the standard bearings for TTE motorsport bearing pack.


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 the 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.
