NOTE: There are different order options and various lead-times on TTE turbochargers. A new unit could be purchased or your turbo can be sent out for the upgrade process. Call or email before placing the order as we will have to factor in shipping costs and current exchange rate and research lead times. For customers with EWG turbos, TTE does not test or recondition the electronic actuator you send. Your sent actuator will be re-installed.
BMW N55 TTE460 UPGRADE TURBOCHARGER
Welcome to our TTE460 Upgrade turbocharger N55 stage. Based on the original turbocharger upgraded for durability and higher performance with stock spool
Maybe the best Plug & play fitting Quick spool higher power option out there.
Engineered & Enhanced
At the core of our TTE460 is a larger TTE compressor wheel, chosen because it is highly efficient and creates an extremely high flow for comparative size. Re-Profiled compressor cover to optimised tolerance to ensure maximum compressor efficiency is given. The original exhaust turbine is retained but modified for greater flow
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 serial numbered balance test result document.
Please Note: For horsepower designations, PS stands for "Pferdestärke", which converts to roughly 98.5HP for every 100PS, so for instance a TTE800 package is roughly 789HP.
