Original Post:
Is there a already a thread where discussing TTE's?

TTE doesn't seem to get as much discussion on AZ as the other turbo options..

Is this due to lack of availability? Because the TTE price point is higher? Or because they aren't AZ vendors?
I expected to find some info on TTE as they appear to be a quality (non-budget) turbo option.

I'd like to find some first hand info on the TTE600 series vs 605's vs K24's, specific to reliability and build quality. The TTE might to have the highest build quality, however this is only my assumption and based on public marketing material and the vendor's descriptions (made in Germany, BW components)

What is a "reinforced 360 degree motorsport bearing system", just a fancied up term for thrust bearing? or Something better?
TTE doesn't seem to offer ball bearings, even on their highest end product the TTE950+. Is this 'motorsport bearing system' that good?, Are the centers that well balanced?

Feel free to PM me if I can find TTE related info on another forum.

Generally speaking, there's been a few threads on here but this one comes to mind: https://www.audizine.com/forum/showt...the-TTE950-kit

The consensus in my mind is TTE makes some very high quality parts that are mostly used by European cars and rarely used in the US (at the least, US owners running these don't post much if at all publicly). Price point is a big factor as is availability however prepare yourself for a lot of back and forth debate on them in this thread. Really depends on your goals and budget.

I'd be willing to try them a try if I can see more data and it becomes more commonly used out here. I've personally never skimped a single penny on my build, however if I'm getting ~90% of the performance out my K24s vs. a comparable TTE offering for 1/3 the price is an attractive value proposition no matter how you slice it.

I run TTE 550's on my 3 liter cactus sedan and will soon be running TTE 950+ setup on my wide body wagon (3 liter). No complaints thus far with the 550's....they absolutely rip.

Whats the story on the 'motorsport 360 degree bearing"?
I'm having a tough time getting past spending the extra money for a 'premium' kit that doesn't have ball bearings.

[projectvoltron]

Subscribing because id like to know about TTE stuff myself

[SoundEfx]

I'll be building my spare engine, so this info will be useful.

[VR6Bomber]

I've been thinking about the tte550 (ko4 exhaust housing?) and tte600 (RS6 exhaust housing?).
I'd like to see a hp/tq curve for each.

The TTE website is comically bad and is void of any real info, they just have pictures as far as I can tell.

If i'm not mistaken, The TTE550 is based off the RS4 k04 and the TTE600s are based off the rs6 k04s

[christianb5s4]

Not to derail the thread, but does anyone know if the TTE y-pipe works with a stock RS4 accordion hose and RS4 lobster claws?

Do you mean THE-Tuner Y-Pipe?
"We mostly use the Y in combination with THE - MAF housing, but it is also possible in combination with the Rs4 MAF. We also offer compatible silicone tubes."

Sounds like you have to buy theirs..?

[dalazybastard]

I too just last week was wondering what they meant by the 360* bearing and did some extensive searching to no avail.

Subbed for hopes of an answer.

Also I noticed if you already have k04’s they will rebuild them for you too make them tte550’s

360 degree thrust bearings are a pretty common thing with newer hybrid turbos. you can google the differences.. Near as I can tell the TTE claims to use OE castings and "custom" wheels.. but they were recently outed as a customer of KTE, a Malaysian manufacturer of turbo impeller wheels.... I suspect they are the standard fare of asian sourced innards. And black paint.

Good turbos? Definitely.

Worth the premium? maybe. depends on what that extra 10% is worth to you I guess.

I usually don't enter these types of discussions because once you start talking about where components come from, all hell breaks loose and this place turns into a scene from lord of the flies.

With that said, why do you make the assumption that wheels from a supplier are not custom? The way you present your argument is that because they come from Malaysia (or is your argument that they come from a supplier?) that they are not in fact custom at all.

Bear in mind, even your favorite manufacturers have to source components to build every component you put on your car or use elsewhere.

I agree that they are expensive, but for me personally, two FT21 failures have forever soured me on budget turbos.

To go a step further, THETuner stuff is expensive as hell too, but I will be supporting their efforts and purchase what i can from them. I realize WDR stuff is cheaper but I value the OE design and the costs that go into that.

Rant over...

I believe that is correct, they both use the same center that is similar to the RS6, and the turbine housing is what is different.
The data from each that I've found looks like you'd expect if comparing K04's to RS6's, the 550 builds torque quicker, but around 4000 rpm the 600 surpasses it and then maintains advantage from there on.

I suspect cost is what makes them a little less used, but then PB5 and TC sell less expensive turbo's and they don't get much attention either.

Sorry, I realized that it was THE-Tuner after the fact.

.

IF you read carefully, i made no such suggestion. They could be a custom part made by KTR for their application, or an off the shelf offering... nothing bad about either possibility. Just stating that they source their parts from the same low cost suppliers that many others do.. I expect they make a very tidy profit.

They do make some awesome looking products no doubt. I would just never pay that much for them.. Im not bashing, im just poor..

[FlyboyS4]

Also I noticed if you already have k04’s they will rebuild them for you too make them tte550’s

It was around 1900 for me to have a set of K04's converted to 550's.

Here is the 550 vs 600 data I compared.

A few pro's for the 550 product I had, the wastegates apparently are stock units that use a different spring setup, presumably better suited to the higher target boost levels.
They port the inlet to the compressor housing.
More than just stating that they balance the turbo's they provide a balance sheet for each one when they're delivered. I believe the 550's were balanced to 250k rpm.

[S4James]

Is TTE porting the hot side? I was under the impression they were.









edit: off topic stuff removed.. dunno why I posted all that...

[TighTT]

I had TTE lighten the turbines on my 550's...just for fun. =)

What/how was the process?

Turnaround time?

As far as ball bearings let’s say tial’s
to these look at the numbers and customer cars floating around. There’s
TTE cars in the 9’s and one or maybe two tial 770 cars in the 10’s. You could always do a custom GT setup. I was about to finish my car and then moved on. For the money you can just do a vrt swap or stk and be done with it.

IMO just because they outsourced the hard and expensive machine work doesn't mean that they still aren't quality products. A 5 axis mill. which is what is required for a turbine wheel, is not a cheap thing to get into. Im sure they still designed and just had some cheaper company cut them. 6065 aluminum (or what they use) is the same across the board.

From the way it sounds they have a pretty stringent quality control and not to mention they still balance everything that leaves there company.

As for the higher price point, I agree. It all depends on if its worth it to you.

To follow up on my original quandary on TTE550 vs TTE600;
From what I found it seems that the TTE550 has a nice lump of tq/hp and tapers down after 4000rpms, and the TTE's keep building all the way until 7000 kind of like how the 770's just don't seem to run out of breath.
I think that I like the TTE600's, but I'd like to hear someone say that the TTE600's are in fact drive-able and that the power doesn't come on so late that you never really are in the powerband

[Drehmoment]

If you are concerned about drive ability 550's hands down, which means city driving with limited open road access. Top end power skip the 600's and go straight to 780's, you have to build the motor for either one, TTE will tell you to get the 780's.

About two weeks from them receiving the used turbos to shipping back the finished product. They would not use the turbine housings from the BW K04's that I sent them (the wastegate passage exits on both had small cracks) so I had to buy a pair they had, so more like $2800 to convert an existing set of K04's.

Im sure they still designed and just had some cheaper company cut them.

I doubt very much they are designing the compressor wheel, unless you mean by picking from a catalog of options.

Pick a boost level you want to operate at and then find a turbo to match it. A turbocharger won't 'run out of breath' if it is operated within the range it was designed for.

[VR6Bomber]

As far as stateside TTE vendors, it appears to be USP and ETEK tuning (Las Vegas)
Anyone heard of or done business with ETEK?
Never heard of them, but their price on the TTE600 is 200$ less than USP.

True, good point.
Your site and information have been very informative and thank you for your contributions.
Why did you move on from the 550's?
And how did you find their quality overall?

I had other turbos I wanted to try out. They seemed like a well put together product, I would not have a problem with using them again.

[GTFORZA]

Here is the things with turbos. I used to work a a turbo shop. 360° thrust bearings increase reliability. Pretty much all turbos use a thrust bearings. Ball bearing turbos pretty much have a ball bearing assembly that replace the journals per say. Next, if you are worried about cheap Asian products, Borgwarner now has a plant in China. It makes the k03/k04 very cheap. Not just because labor, but because the plant increases production volume. Finally, a CNC milled part is only as good as its materials, it's design, and the CNC resolution. That being said. As long as parts check all those boxes it will make zero difference as to where it is made.

BW having a plant in China does not to address the concerns about the quality of non-BW turbos.

Do you know the material used for the TTE bearings? Were they bronze?

Your impressions of the TTE550 vs the tial 605's, as far as performance characteristics?
I only ask this b/c I had a 605 car, I have that as a personal point of reference. I'm not comparing or considering 605s right now.

[S4James]

think of the TTE 550 like a well sorted k04/rs6 hybrid

[TighTT]

I believe his point is/was that just because something is make in China, does not necessarily condemn to the product to inferiority, using BW as an example (make in China but with proper (hopefully) QC procedures).

I did not disassemble them. Contact Simon at TTE, he was very good about responding to questions I had.

The 550 is similar to performance of other K04 hybrids like the F21 and SRM's K04.

I had the 605v1, the difference was as expected, quicker spool up from the 550 and more top end from the 605.

[1ScientisT]

I have been running TTE550 turbos on my S4 for two seasons now (maybe 9-10k miles). HS Tuning in Westlake, OH is the TTE dealer I used, which is luckily pretty close to where I live. They shipped my worn RS4 K04 turbos out, and the finished TTE550s showed up about 6 weeks later. Rebuild was approximately $1700, and I was out of pocket around $2100 total including shipping. On a stock block/heads/cams, they hit hard around 4k rpm and slowly taper to redline. The car is pretty quick...runs dead even with my friend's blown e39 M5. On a side note, the TTE550s have to be the loudest small frame turbos I've heard. The car sounds absolutely menacing when just casually rowing gears, and I've had more than one potential sparring partner think better of it after cruising next to me. Probably going to be selling mine this winter in favor of 770s.

[Perth_RS4]

I run TTE 550's on my 3 liter cactus sedan. No complaints thus far with the 550's....they absolutely rip.

Do you have a dyno graph or some data on this setup?
I have wondered how these would perform on a 3 liter setup.

[landfill]

I was saying in your OP your worried
about finding quality turbos with ball bearing chra’s. The top ball bearing choice for the 2.7t is tial 770’s. The tial turbos and even Garrett kits have nowhere near the proven dyno and track results compared to the TTE cars from across the pond. If you want the best of the best in twin configuration for the 2.7t then TTE is where you want to spend your money.

They are the best turbo option we have currently imo. Just listening to the TTE cars is mind blowing.
