Anybody using the TTE 420 turbo?

[GIACUser]

Looking for any info on performance and tuning. With the dollar being strong against the Euro, I am considering this and putting in a set of drop-in rods. I am of course assuming they are still available.

Simon wrote me back this morning and the cost is 2250 shipped. I suspect I could get 750 ish for my K04 that has about 17kmi on it which would make my out of pocket about 1500 ish.

What I hope to find are other owners I can trade emails with that have owned one and even some folks that may have gone from regular K04 to this modified K04 and their experiences with tuning software. If I could just run what I have that would be great.

$2250? I bought my HTA3586 for 2200. Any info on this turbo? Sounds pricey

Standard press on the product. It is a modified K04. Audi popular.

TTE420 Upgrade Turbocharger 2.0 TFSI



TTE420+ begins as a brand new standard BorgWarner K04-064 turbocharger that we dismantle and then set about upgrading and optimizing as engineers to create the our ultimate K04 frame hybrid. TTE420+ Turbocharger is in our opinion the final step and our pinnacle power stage for the 2.0 TFSI range of vehicles while retaining the OE K04 unit for Plug & Play fitment.

Engineered & Enhanced

The formula to making a TTE420 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 also fit our TTE CNC K04 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.

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 ittle loss or same response vs stock K04 yet huge gains in power and torque.

Attention can be given to port the exhaust runners at the flange to match and smooth the transition from head to exhaust runner for maximum gas speed and so improving efficiency to the much bigger K16 turbine and so driving the compressor harder. This Process is avalible at extra cost.

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 dynamically in multiple planes using our single parts machine, then components are assembled and then the CHRA are balanced yet again but this time at up to 250,000 RPM using our in house VSR machine to acquire the ultimate equilibrium. Each and every turbocharger is supplied with a balance test result document.

WAY too expensive for what it is IMO. For that kind of money, get a large frame garrett or precision and fill in the rest of that cost with whatever other supporting mods you need on your car

 

[ViRtUaLheretic]

Sounds like the LOBA kit

 

[donjuan1jr]

Yea I wouldn't buy that.

 

[GIACUser]

Sounds like a pass then, well I guess just stay with what I have for now. I did more searching and the small gains would not justify the cost. Looks like I might gain some over what I have but at a very high $ per hp.

Very similar except the LOBA uses a BW EFR series right?

Wow and I though the EFR and new Xona Rotor turbos were expensive, $2250 is way too much for a modified K04. lol

gtx30 perhaps? ive seen from the mk6 side making 400whp to 500whp

A GTX3071r would make that much power, another option would be a BW S200 57mm which is rated at 64 lbs/min and is around $1350. Only downside is it is journal bearing. Basically it is a EFR 7670 in sheep's clothing. lol

BW S200 57mm

The Xona Rotor 65-64 is rated at 65 lbs/min, but is $2099. It has a larger exhaust wheel then the GTX30's.


Stainless steel bearing housing
360 Degree Water Jacket
Ceramic dual ball bearing
Compressor wheel - 57MM Inducer / 79MM Exducer
Turbine Outlet - 64.1MM

The TTE420 should not be compared with the Loba unit.

Dyno before and after TTE420, 47hp and 61Nm increase =)
Difference between the dyno sessions are TTE420, APR LPFP system, 165bar FPRV and new spark plugs.

Engine code BWJ, stock internals, stock injectors
* APR 3.4 K04 98 map, 98 RON fuel
* Flapper delete
* WMI, DO3 nozzle in throttle body plate (pass TB), DO3 nozzle in throttle pipe after Intercooler
* 3" DP, Catless, 3" cat-back
