TTE390 Upgrade Turbocharger VAG 1.8T 20V
TTE390 for the 1.8T begins as a brand new standard BorgWarner K04-064 turbocharger taken from the 2.0tfsi platform, we dismantle and then set about upgrading and optimizing as engineers to create the ultimate K04 TFSI hybrid for the 1.8T VAG platform. This turbo shares same spec as our TTE420 for the 2.0TFSI, proven at over 420PS without wmi. CNC modified Exhaust manifold for fitment for the 1.8T VAG platform so does not require a spacer plate others are using. Comes with CNC Exhaust manifold mounting adaptation hardware.
Engineered & Enhanced
The formula to making a TTE390 starts with a much larger 2871 BorgWarner compressor wheel, chosen because is highly efficient, new generation type with ultra thin blades, creating extremely high flow for comparative size, giving a compressor map that's very wide. Yielding a maximum air flow rate of 310 litres a second, compared to a stock 2283 compressor at 250 litres. The Re-Profiled compressor cover is machined to a optimized tolerance to ensure maximum compressor efficiency is given. Also the intake pipe is ported to give a smooth transition for the incoming air flow. We fit our TTE CNC silencer delete, we modify the turbo discharge silencer, removing the 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.
A key part to driving the large 2871 compressor and in turn making this unit produce the huge power advantage over stock and also the competition, 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 types other company's are still using.
The clipping of the K16 turbine is a special TTE grinding process to the turbine blade tips, curved to alleviate stress from process. Clipping reduces blade area thus increasing gas flow and so reducing back pressure and lowering exhaust gas temperatures, allowing safer higher boost level's. This process also gives a secondary advantage of removing some material, lightening the turbine thus reducing rotational mass improving moment of inertia. Dyno's have shown near no 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.
Actuator used is uprated sprung OE unit, fitted with our reinforced clamps for trouble free operation. This also can also be modified to customer needs and specifications.
Equilibrium
Precisely balancing our turbochargers is a key critical factor for longevity and performance. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers with this regard. 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 yet again but this time 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. Supplied with a balance test result document.
