Turbo Lady Tial 770 - current turbo options

[julex]

Hi all,

I've had these for many years on what's a daily driver car and they started singing the tone nobody likes to hear. I think I can fully blame the exhaust shop for this as after doing my cats and flex pipe replacement one year ago, I immediately noticed some new noise/whistling from exhaust on pulls which I bet was due to them welding 2.5" flanges to 3" DPs and creating some obstruction. They also put undersized cats on which I only noticed recently... Anyhow, lesson learned there - get a reputable shop to do the work...

The car is an allroad with everything built to handle tial 770 at their max (dynoed 625WHP before the exhaust fiasco) so any option is in game. I plan to go back to exhaust with dumps to open up things when DD mode is off. I would like to go back to quicker spooling turbos than 770 with the goal to being a little more street friendly although if Tial 770 is still a good choice then perhaps I will stay at that.

With that, can i get some recommendations for new turbos based on a fact that I am years behind and not following forums closely for a long time now? I am looking for something spooling faster than 770 but still capable of putting down respectable torque on the pavement. That excludes PJ k04 but not RS4/RS6 hybrids.

SEP 8 blade?
JHM RS6R?
SRM RS6?
K24?

I think you’d be disappointed going with any of those rs6 hybrids. From personal experience adding cats really hinders spool so I bet with a catless DPs you gain what you’re looking for. My car with F21s gained about 250-350rpm of spool ditching the cats.

Otherwise the TTE780s spool extremely quick for the power they make.....they really didn’t seem to have any more lag over my F21s.

[slow ride]

I think I'd check with Robert and the guys at Forced Performance if they have any options for the current turbos. It's sort of hard to downsize in the same housings, but different exhaust/intake wheels can change things a bit.

Oem rs6 turbos for great response and around 500hp

What Garrett for better spool?

[christianb5s4]

I've had my eyes on Garrett G25s lately, huge potential and are an 'up and coming' with several in Europe getting insane results. However, that involves a lot of custom work and no one makes a kit (yet).

How much custom work are you interested in doing?

I assume that both of you guys are running Garrets on your B5's? If so, who made your manifolds, etc?

[Scribble]

Legendary Performance Group looks to make a header/downpipe kit to support the G25’s. They also have a pretty snazzy looking airbox location STK. No affiliation.

[replica_rs4]

The tuner has cast manifolds available with vband and pretty sure there is a whole kit option for g25 turbos.

There are a couple of different kits available

Nope, but if I decide to put my AZR in, it's the only setup I'll go with. The wide array of turbos available, and their overall characteristics and reliability make them a no brainer for someone who wants more than what an RS6 can do. I won't do any hybrid turbo, just not worth the hassle for the amount I drive my car (15k ish a year). I'm only familiar with the kits in passing. I have to first decide if I want to go down that road, or fit the widebody, or simply leave things as they currently are for 2022.

There are setups out there as far as install - James Young does one as does 27Motorsport (theirs may not be finished and shippable quite yet).

Currently running Garrett GT28RS CHRA’s in some SRM housings. THETuner made a one off G25-660 kit for me, but the way I want to do the build is pretty intensive with long lead times on parts, so not sure when/if it will ever get done. The turbochargers themselves have great potential. Other platforms have had great results with them. The Nissan GTR was able to crack 1150whp running an 8.64 @ 161.5 mph on 93 octane and meth with the G25-660’s fitted into its stock exhaust/manifold one piece (VERY small A/R). The way they designed the exhaust wheel geometry is great as it flows a lot for its relatively small size. Had I known this I might’ve gone with the 0.49 A/R vs the 0.72 A/R, since the marginal gains up top might not be worth the sacrificed mid range down low, especially with the success I’ve seen a couple vehicles have had with them in more restrictive housings.

They no longer offer the kit unfortunately, Andreas made two and called it quits. Only person that produces them is James Young as mentioned.

Their new club line is pretty nice, as it’s their new offering to fill in the sub 300hp gap that they have. Their sizes are comparable in range to KO3s to RS6’s, but they would require custom work though to fit. For anything sub 600whp I would just stick with the Borg Warner options as they are proven and made by one of the largest OE turbo suppliers.

Thats disappointing . That was a really sweet option. Do you know if the cast manifolds are still being offered with vband option?

They never did unfortunately. They did at one point have a v band adapter concept with the idea of getting rid of the need of custom welded manifolds (more prone to cracking) and be able to use their cast manifolds universally with IWG Vband turbo options, but unfortunately nothing ever came of that as all turbo options would still require a lot of modification/work.

MCP, may i ask how your results have been on those SRM units? thinking of upgrading myself from the classic JB ones i got 5 years ago.

Haven’t finished tuning mine yet, but another user on here ran a 11.2 @132mph and claimed to have around 600whp with same spool as his F21 turbos and better transient response. Remember these are the old GT28RS units that flow approximately 36lbs/min. They supposedly only sell them with the GTX2863r and GTX2867r (im assuming it’s a Gen 1) CHRA’s now which flow approximately 43lbs/min and 47lbs/min respectively.

Thanks for all the feedback so far.

Having read through the mega TTE thread few pages down, I am not sure I want to go that route seeing all the drama and issues cropping up.

As far as STK, is that still a thing? I can see two kits at this point of time, the PB5/XS kit and Legendary kit. Summing cost up, it looks like I can have an STK car with modern accessible turbo which I can swap anytime I have a need to for about the same cost as TTE set which I wouldn't want anyway.

[Silverex]

FWIW: The TTE thread turned to shit after a vendor got cut off from selling those turbos which started the drama. Same vendor was praising the turbos a few months prior yet was posting failures which happened in the past...all of those failures didn’t just happen recently. Also no one posted a failure that was for sure from poor quality/workmanship. With that said it doesn’t seem like TTE customer service is the best and dealing with a company over the pond can be a pain.

STK is definitely still a thing and if your willing to do what’s necessary for install it is a great option since you can really dial your setup in with swapping exhaust housings and/or turbo. I really wanted to go that route but don’t want to run a front mount intercooler.

The twin G25-550 setups do make great power but they will add a decent amount of lag over the 770s and really need a all out build to take advantage.

Another option would be to build your own twin setup using the new exhaust housings The Tuner makes which have a larger AR than RS6 turbos but still bolt on like stock. But if I was in your shoes I’d probably just have FP or similar update your turbos. Never been in a 770 car but from the videos I’ve seen they seem to have a great balance of power & spool.

[julex]

770s sure can spool up, maybe not like k04 but it is a freight train once they hit. This is why I am on the fence here. On my set up I would see 20psi 3250ish and have full boost ~4k rpms:

THETuner exhaust housings are actually even larger than the TIALs so if anything they would probably lag even more. Would be interesting though to see what you could mate up to them and the results it’d give

Is it just me or does it look like the torque ramp is held back a bit up until the 3250rpm mark? Either way that graph actually looks very nice, 20 psi by 3250rpm is great spool for turbos those size and the torque isn’t that far offset from Ko4s

What are the tials....7cm DSM housings modified for a S4?

While a larger exhaust housing usually adds lag that not always the case and you can’t really compare AR from different manufacturers since they can vary a lot. Like garret T4 vs BW T4s even in same AR are visually different.

Dude that graph looks awesome! I wouldn’t even think twice about keeping them and rebuilding.

at around 10psi pre-cat dumps open - the are controlled via 1psi actuators which are then controlled by very simple manual boost controller so I can set the cracking pressure to anything I want. I keep it at around 10 psi - this is about right to not thunder around when some power is needed but still open when it is WOT time. This is why you see torque ramp up around that spot as engine can breathe freely.

Yep, 7cm vs 8cm, and that is true, you wouldn’t know until it is tested, but either way it’s a cool aftermarket option to have.

Makes sense, honestly this set-up is pretty killer, are you sure you wouldn’t miss the power by downsizing? I also like the classic torque hit character that a KO3/KO4 car exhibits, but judging from the graphs you’re not giving up that much and what you’ve got is what most people strive to have on our platform.

Did you just try to sell TTEs to Julex??
Son, do you know who Julex is??, and how much he has actually contributed to developmant of B5 hardware and software?
You are still a sperm in your dads balls comapared to guys thats actually been doing the work all these years.
You are spreading way too much bad information.
You are a Simple wannabe. A loud mouth. Jockrider.
You never owned a TTE780s, Never built or tuned it.
You have never seen anything even close to G25s.
What K08s are you talking about?I just built and delivered a set.
As a matter of fact closest you ever come to any of these is reading or looking at my work.

You built a entering level car with China F21s that runs FATs 4 sec. This was not impressive even 10 years ago.
Your thread is on this forum.
Why are you giving ppl advice on these levels?
You have no clue what you are talking about with high power.
Stop it and STFU!!

GET OFF MY BACK!!!


Guys, I will guess something here.

Pj Kennedy aka SelverX has gotten a sweat deal from Simon Sharp on some TTEs.
He will be talking sweat around it from now on.
Mark my words!!

Julex, been along time.
As i remember you, you was never intrested in any kind of China turbos??
All of these you mentioned are just that.
TTE has also gone 9 blade China wheels since last year. But you need no explanations. See for yourself.
Only TTE turbo for this platform that uses BW is actually still 780s But,be careful they surge, spec using Big intakes as they will kill themself. Also, they are sevirely underpowered on petrol. E85 is good deal.
Petrol, you are looking at 450-500whp. E85 lots more.
Thats been posted here several times. I just tuned a set, couple of weeks ago, horrible surge.


MCP is right about G25s,
Everything you have seen from THE_Tuner about G25 was me pushing it. It will not be more. It needed lots of cutting and redooing to actually work. Not an issue to me. I rebuilt it and made it happened anyway.
Results posted on our site.
Its too expensive, too time taking and colides with their K08 concept.
THE is not intrested any more.
We do work on G25 solutions aws without THE.

Dude idk what your problem with me. I’ve never been anything but cordial to you even tho you’re a complete douche to me for whatever reason. I purposely didn’t put your name hoping you wouldn’t comment since it seems like the only time you contribute is to bash TTE recently.

My car is not fast it does 3.4s fats in the summer....not 4s even tho I’ve corrected you before on that.

I also never tried to sell him 780s was laying out the options since he was asking.
I’ve never talked to Simon about getting free turbos or anything from him not sure why you’d think that.

Once again I’ll ask for some clarification on this “bad information I’ve been spreading” I’ve never claim to be god and even if I was I’d still be willing to learn something new from someone else, so by all means school me.

[slow ride]

Good lord lol this place sometimes. Julex your past log looks pretty damn good, I assume it's 4th gear? Anyway the reason I mentioned checking with a refresh price so it's just plug and play. I think the Garrett stuff is badass also, but that is a decent amount of commitment and not sure spool would be better (probably worse) but of course g25 550's would make more jam cranked up on good fuel. I believe Julex runs pump/meth so some fuel limitations also.

Childish comments aside, I am genuinely looking forward to some feedback from the TTH/K08 offerings.

Do you have any info to share about the 780’s? I’ve been looking at those, the 860(780 with the larger 08 turbine housings) and the 960’s.
I currently have the SRM RS6/K24 making 590whp on E85, 27psi.

I do not personally only went for a ride in one. I’d send vr6bomber a pm and talk to him. His setup isn’t fully tuned but it’s probably pretty close and maybe he’ll share some logs with ya to get an idea.

Just my 2cents: I’d wait for some more results/data to come out on the 860s to see how they compare to the 780s since for all around spool and power they do pretty well. I’d assume the larger turbine would help but no idea on if it will affect response much. Have you thought about the tial 770s....that graph is pretty fucking good posted above.

Agreed, 20psi before 3500 is great. Are the 770’s even available anymore? Or I’d have to find a used set and recondition/inspect.
