The Turbo Engineers TTE420 Turbocharger - VW Mk5, Mk6, B6, Audi 8P A3, 8J TT, TTS 2.0T FSI
Audi, VW 2.0T FSI EA113 TTE420 TURBOCHARGER
The TTE420 begins as a brand new standard BorgWarner K04-064 turbocharger that TTE dismantles and then sets about upgrading and optimizing as engineers to create a fast spooling and powerful K04 frame hybrid. TTE420 Turbocharger is great power stage for the 2.0 TFSI range of vehicles while retaining the OE K04 unit for Plug & Play fitment.
Important note* While the hardware in this listing is compatible with your vehicle it is possible that the required tuning is not. To confirm ECU tuning is available for your car, your vehicle's ECU box code must be identified. If you own VAG COM, OBDeleven, Carista, or have access to factory VW/Audi diagnostic tooling, you can follow this guide to identify your ECU box code. You can also visit either New German Performance shop location and our staff will be happy to assist. The customer assumes all risk if this turbocharger purchased and installed without first confirming the required software is available. No returns are accepted for installed turbocharger kits.
Please note that if you choose to upgrade your existing turbocharger, it will have to be shipped out of the country. The typical turn around time for this turbocharger is around 30 days depending on what shipping options you use. Please click or tap here for more information on this process.
Engineered & Enhanced
The formula to making a TTE420 starts with a much larger 2871X TTE billet compressor wheel, chosen because is highly efficient, new generation type with very thin blades, creating an extremely high flow for comparative size, giving a compressor map that's very wide. The Re-Profiled compressor cover is machined to an optimised tolerance to ensure maximum compressor efficiency is given. Also, the intake pipe is ported to give a smooth transition for the incoming air flow. TTE also fits their TTE CNC K04 silencer delete, TTE modifies the turbo discharge silencer, removing the baffle internals and fitting a new straight through section, removing any restriction and its function as a noise canceling device, so improving the flow and enhancing the sound.
A key part to driving the large 2871X compressor and in turn making this unit produce the huge power advantage overstock and also the TTE400 upgrade hybrid, is machining and fitting a far larger BorgWarner K16 curved clipped turbine and shaft, while still keeping the k04 core, this is not so easy to do. This K16 turbine gives much lower back pressure and keeps EGT lower compared to stock K04 turbine or clipped stock.
The clipping of the K16 turbine. Clipping reduces blade area thus increasing gas flow and so reducing backpressure and lowering exhaust gas temperatures, allowing safer higher boost levels. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing the rotational mass improving moment of inertia. Dyno's have shown a little loss in response vs stock K04 yet huge gains in power and torque.
Special TTE developed in house 360 deg high-performance motorsport journal bearing system is fitted. Durable at high loads with no loss in transient response.
The actuator used is uprated sprung OE unit, fitted with TTE reinforced clamps for trouble-free operation. This also can also be modified to customer needs and specifications.
Equilibrium
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 their balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using their 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 the TTE 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.
