TTE4XX 5154 UPGRADE TURBOCHARGER ALFA ROMEO 4C 1750 TBi

Note! If you upgrade the old superchargers, they must be in good condition so that there are no additional costs for upgrading the superchargers.

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.

Equilibrium

Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as Longevity and performance are paramount. Good balance also improves acoustics. Subsequent great care is taken with all TTE turbochargers to achieve 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.
