    Introducing our TTE625 performance turbocharger based on the original 8S turbocharger to new higher output specification. Offering an upgrade to over 600PS.

    Engineered & Enhanced

    At the core of our TTE625 is a much 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.

    We CNC mill the exhaust turbine housing to accept a larger turbine and shaft.

    Special profile 360 deg high-performance motorsport journal bearing is fitted, to remain durable at higher loads with no loss in transient response. The actuator used is sprung OE unit

    If ordering new, we use the latest generation of BorgWarner original turbochargers with the latest spec Audi thermal shielding on the exhaust manifold & turbine housing to lower engine bay temperatures and ensure the best performance and safety.   Please note if you send an older generation turbo, without the original thermal shielding for the "upgrade" process, we will rework your turbo and return without the shielding.   


    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.
