TTE525R Performance Upgrade Turbocharger VW GOLF R & GTI MK 7 / AUDI S1 / AUDI TTS / AUDI S3 8V / AUDI Q S3 / LEON CUPRA & SC 5F / SKODA OCTAVIA vRS 5E / SKODA SUPERB SPORTLINE TTE525 is our latest hybrid performance upgrade turbocharger for the new 3rd generation VAG 2.0TSI following on from our proven TTE470 upgrade stage. Stage 3 power, same near stock turbocharger spool and response. Engineered & Enhanced To construct a TTE525R we change the original compressor and employ a far larger and more efficient billet wheel with extended tip technology and mill the compressor cover to optimum gap to match the new compressor profile. We replace the original IS38 turbine and shaft and CNC mill the turbine housing and install a larger clipped and lightened turbine for greater gas flow. We CNC modify original compressor cover, for increased airflow. We replace the original recirculation solenoid valve with a Motorsport atmospheric blow-off valve that's included in the price. We also fit our TTE CNC silencer delete. Modifying the turbo discharge silencer, removing the original baffle internals and fitting a new straight through section, removing any restriction and its function as a noise cancelling device, and so improving the flow, giving less surge and enhancing the sound. The clipping of the turbine is a special TTE grinding process to the turbine blade tips. Curved to alleviate stress from a process. Clipping reduces blade area thus increasing gas flow and so reducing backpressure and lowering exhaust gas temperatures, allowing safer higher boost level. This process also gives a secondary advantage of removing some material, lightening an already lightened turbine thus reducing the rotational mass improving moment of inertia, meaning fast spool up. 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 serial numbered balance test result document.
