The TTE580 VTG Turbo upgrade for the 718 horizontally-opposed flat-4 turbocharged 2.5L displacement motor. Still keeping the series model turbocharger that utilizes Variable Turbine Geometry (VTG) technology but utilizing a larger higher flowing 9 blade turbine and fitment of a bigger 7+7 blade milled billet compressor so producing extra power yet still giving that VTG early response.
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 strict balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using a 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 a 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.
