TTE800 6361 BMW B58 UPGRADE TURBOCHARGERS & SUPERSIZE INLET gen 1 (images shown with heat shield option)
The largest B58 TTE hybrid based on the Orgiinal MAHLE turbocharger. Big power without big lag..
To construct a TTE800 turbos we removed the original compressor wheels and employ a far larger and more efficient 63mm inlet 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 61 mm turbine in the turbine housing for greater flow and lower exhaust gas temperatures at high boost and designed and fitted our upgrade bearing pack for durability.
We also supply TTE upgrade turbo inlet intake for connection
Equilibrium
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.
