The TTE475 for the MQB 2.0L displacement motor, evolving from the popular TTE470, sharing the same proven compressor and turbine, just now with the original recirc function. Still keeping the original turbocharger turbine but clipping the original blades for greater flow and to lower exhaust gas temperatures. TTE fit a bigger 7+7 blade milled billet compressor so producing extra power but focused on like OEM IS38 response
The Turbo Engineers also fit their CNC silencer delete. Modifying the turbo discharge silencer, removing the original baffle internals and fitting a new straight through the section, removing any restriction and its function as a noise canceling device, and so improving the flow and enhancing the sound.
TTE also replaced the original thrust bearing for TTE upgrade 360 deg that is made in-house.
Precisely balancing 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 TTE's 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.
