CTS Turbo BOSS Turbo Kit

[kradgsxr2]

Hey guys sadly I totaled my Avant hit a wild boar at 130 that’s what I get for speeding. I have a P3 gauge with the timers red numbers, vagcom cable with one vin available for sure and the eurodyne cable for there tuning suite. PM me if you want to buy them. Shoot me an offer first reasonable offer gets all three.

you hit a wild board at ..... 130mph, what does the car look like?

I think it's about time this upcoming (Bolt-On Speed Solution) turbo kit has its own thread.

I aggregated the posts I found about it, and posted the date at the top of each quote...



They posted the following on their FB page on 11/23/16...

Gary Parga R - Hello I have a Audi A5 2.0 2010, I want a bigger turbo for my car comes out and if they send guadalajara mex
CTS Turbo - Then you may want something like this, we're working on one for the B8's too

https://scontent.fhou1-1.fna.fbcdn.net/t31.0-8/15110986_1312713512114644_4897537207408972827_o.jp g

I recognize that as an EA113 2.0T FSI engine (Mk5 GTI, Mk6 R), but hardware for our EA888.2 engines is very similar. Makes me wonder if a K04 tune could be utilized until a tune calibrated specifically for the turbo comes out. United Motorsports installed the similar Mk7 MQB version of the BOSS kit, so I assume they might be an initial source for software. The Mk7 EA888.3 MQB kits shipped in October 2016, but the exhaust housing is completely different from the EA113 and our EA888.2 engines.

These CTS BOSS kits are utilizing a Garret GTX2867R or GTX3071R turbo installed into a CTS proprietary exhaust housing. I'm pretty stoked for this.


I wonder if this will ever happen??

you could always swap the chra on your k04 for something with bigger wheels, the housing would just need to be bored to match. i have a thread on it.

I've been following man, excited on what your findings will be!

[Spawne32]

should have results from the first users swap soon, no one has done the larger non k04 spec stuff yet though

[SILVERBACK004]

I have to agree, the K04 is a nice upgrade. When I get tired I add E85 but feel like I need more power. I have been following the CTS Instagram on some of their Boss Kits and try to send them a message about the Audi B8/B8.5 platforms no response at all. I love my A4 but now looking at the S4, S6, & RS3...

That's why I have been exploring options with the existing K04 housings, because we aint ever gonna see this boss setup on a A4, especially not a B8/B8.5.

It seems tuning is always the issue with going bigger than K04.

I thought we would get away with that with HPtuners but I haven't found anyone that understands wtf is going on with our ECU. lol Had my buddy look at it the other day and he's pretty sure its using the gravitational constant to measure airflow.

[SILVERBACK004]

I'm currently running the APR K04, do you guys know if there's a better tuning option like a custom one?

How much hp power would the car be pushing on e85? Can the engine and transmission handle it?

Or tune options, or supplement fueling needed.

[Nano909]

All someone has to do is buy it, install it, custom tune it to whatever fuel you're going to be using, and post results. No need to keep complaining about the same things over and over.

I bought this kit and have it installed on car. I wouldn’t recommend it. The quality control on it is horrible. 3D printed hose adapter. Metal shavings in the compressor housing. Poor instructions. I think pagparts is coming out with a b8 kit soon. Depending on the cost of that it. I might be worth to wait for that.

Jesus Christ. Is CTS working with you to fix all of that?

[Carlos74]

I know a guy in STL that installed the boss kit in his B8.5. He recently posted the kit for sale, he said he couldn’t find someone to tune it. Not sure if they couldn’t tune it due to the lack of supporting upgrades or what but he said he’s done with it lol.

At this point, I really think the best option is going custom (with proper internals and fueling of course):

Tuning is the biggest issue. No one wants to do custom tunes .

[dadwgn]

I have a great tuner here in Vegas and looking to run this kit in place of my k04+e85+wmi . Thinking I can sell my k04/test pipe/intake for a decent price to get the boss500

[dadwgn]

Thread seems pretty dead but I've had the Boss500 installed on my b8.5 Allroad for about 4 months now and wanted to give you guys an updated.

Went from the CTS K04 to the BOSS500 as my tuner said my car could handle the bigger turbo and he could tune for it. He put some hours in tuning for sure. Had issues figuring out how to raise the torque limiter. We had been tuning for e85 as well since that's what I was running on the k04. Car didn't run 100% on e85 with the gtx2867r. Tuner said we needed bigger MAF and MAP sensor for more boost. We went that route and decided to try the car on 91 pump gas. Dyno'd at 422HP and the car is running solid!

Next steps will be fueling/pistons/injectors then tuning for e85 again!

I would be impressed if this was horsepower to the wheels. Why put a car on a dyno to calculate a known figure, then convert the known figure to an estimate (CHP)? The best way to calculate CHP is on an engine dyno.

Next time have them display WHP instead of CHP.

[Spawne32]

That would make a hell of a lot more sense as to why those numbers are so high. lol

[JLAllroad]

I’m guessing the boost that is graphed is total pressure (2.5 bar) and after you remove ambient of 95.3kpa(13.82) it puts you at 22.95psi, does this sound about right?

What kind of MAF, IAT, and timing are you hitting?

https://www.audizine.com/forum/showthread.php/699070-B8-Ko4-owners-follow-up-thread/page92

It looks like he used the same tuner and same Dyno for his big turbo. The strange thing is that it gained only 17 HP more than his K04 did.

If the above is correct then the power is probably boost limited, and that may be because of the hard limit everyone else has run into. Or it’s artificially being limited because additional fueling will be necessary once boost is kicked beyond 24+ psi in the upper rev range.

This was at low boost 18-19psi.
We just turned it up to about 22psi which I believe he said was 1.5 bar.

Correct. We were maxed out on high boost (24-25psi) running e85 with the k04.
This is low boost (18-19psi) on 91.
Turned it up to 22psi yesterday on 91
Will be looking to do pistons/injectors/hpfp/lpfp and e85 next. Should put me close to 500HP

Yah, I think that's why it wasn't running 100% on e85. Plans to upgrade fueling next.

By the time you get done it would probably be cheaper to do a gen3 swap with an is38.

[Traptalk]

RTM does remote tuning seeing as you’re in Vegas and he’s European?

[dadwgn]

which gen 3?
I actually traded my k04 for the Boss500 with a guy who couldn't find someone to tune it on his b8a4. So no extra money spent on it.

Those pics are your car on the dyno though right? The measurement is coming from the wheels, so there is a flaw in the logic. The number he is displaying is merely a calculation based on what he estimates the drivetrain loss to be.

[dadwgn]

So should I be concerned that he’s been tuning cars the wrong way?

[Spawne32]

I mean it still works, its just that the accuracy of the number you are getting is totally up in the air. Just do some simple math. If your making 422 crank horsepower and hes using 20% drivetrain loss as the estimate, your making 338 wheel horsepower, but if its 422 chp and hes using 25% drivetrain loss, your making 317whp, but....what if hes using 15% drivetrain loss as his estimate, well then theoretically your making 359whp. See how it goes? Crank horsepower on a wheel dyno is just a game of numbers. In my opinion, tuners that claim that they "only tune in crank horsepower because its more accurate" are doing a marketing gimmick which makes their customers think they are getting outrageous numbers with their tunes.

[dadwgn]

I get what your saying now.
He’s the opposite of tuning high numbers used for marketing purposes though. Whenever I’ve asked if we can go higher boost he’s advised against it if it wasn’t safe 🤷🏾*♂️. He’s pretty conservative I’d say. Maybe scope out there IG @rtmperfomance and let me know whatcha think.

Most good tuners won't tune a car to unsafe levels because when you do that and the customer blows their car up down the street, they come right back complaining. lol That's why alot of OTS tunes for our cars are run either on the rich side or have extremely low ignition timing compared to what you can actually squeeze out of each individual car. They paint with broad strokes to cover any car that it gets put on regardless of the particulars of each individual vehicle, that makes them pretty much safe to sell to anyone. I don't doubt the tuning skills, I just think it misrepresents the car's actual power when you do something like that with "estimations" of crank horsepower. Show me the actual power getting to the wheels, because that's all that actually matters. You could have an "estimated" 1200hp at the crank, but if its putting down 300 to the wheels, your no faster than any other car with 300 at the wheels. (This is an extreme exaggeration.)

Circling back to this, didn’t mean to ignore you.

Stock and even modified to K04 standards this car is a torque monster not designed for high RPM running. The larger the turbo the more you shift the power band to the higher RPMs, and losing torque in the lower range.

To make this worthwhile you will want to run high boost (more than 24) and extend the RPM range to 7000+.

Your going to need a built head (at minimum valve springs) as stock does not like high boost/rpm. Above 7K rpms you may need additional timing gear, as it’s not known to be robust, but at that point you are in somewhat uncharted territory.

Then there is the ECU’s reluctance to allow boost beyond 24psi without closing the throttle. I’ve only known APR to tune around it and they’re not telling anyone how they did it. Outside of that there are piggy back stacking or stand alone ECU.

I know you are planning on building the bottom, pretty straightforward, maybe look to lower your compression ratio. And addressing fueling, this is going to be complex, I know of another that utilized an upgraded 5th port injector.

Otherwise maximize your current turbo set up as your not even to it’s maximum potential.

This is why so few go beyond K04 on this motor.

Here is a good thread, note “stock internals”

Appreciate all of the feedback!
Fueling is on the way so that I can run full e85 and hope to get closer to 500HP.
Although I have been playing with an e30 mix which the car seems to respond well too.
Current shifts are set at 7200-7300 running 22 psi of boost.
I guess for now you’re probably right on maximizing this setup first so let me give it a go.

RS3 injector? From last DWNA/DAZA version?
DO they fit?

[Mars2]

I'm not sure DAZA/DWNA injector flow more as those RS3 has GDI and Port injection.
Older RS3 injector will not fit in EA888.2 they fit EA113.

To my knowledge the GDI injector that flow most and is not pain in the ass to tune is G7R Injector. But I could be wrong.
Nostrum flow much more but pain in the ass to tune idle.

Guess I'll find out soon. LOL

Those RS3 injector are very famous on EA113.
I don't think they fit EA888.2 without modification.

There’s a guy on YouTube that made a series about the Boss kit. Look him up. If I remember correctly it’s Flink Films

United Motorsports tune. 20+ pulls on the dyno and a rod bearing goes out?

Oh, bummer:

I know this thread is old but i want to install a BOSS 500 turbo as well but it didn't come with instructions and all instructions i see is to transfer lines and connectors to new turbo but the new tubro doesn't have as many hoses and ports as stock turbo so where do i put them??? Do you have clearer doesn't that could help me out?

It's basically self explanatory.

I read the entire thread, but would the boss600 be better for me if I want top end? I do a lot of highway driving and willing to sacrifice some low end for more top end for the occasional fun

I bought pistons and will be getting forged rods soon. From my understanding, forged internals and fueling upgrades (034 hpfp upgrade + bigger injectors) with ethanol can make mid 400s with the boss500

If I purchase the items needed for upgraded valve springs (basically building the head), would I be able to get close to the 500whp mark? While retaining daily driving? Or should I just stick with what pretty much everyone else runs (IE: forged internals + fueling upgrades for mid 400s with the boss500 kit)?

I'm not concerned about tuning side of things since I will be contacting WPT to tune the BT. I also will be working with Melen TCU to tune the trans. I'm currently running both their tunes with my k04 with ethanol and it's fun but I wish to have more top end

My plan is to run this:

IE Spec Mahle pistons
IE H beam rods
Mahle race bearings
IE Valve Spring & Retainer kit with the Ferrea intake & exhaust valves

My reasoning for these parts is to compliment each other for my certain use case rather than overbuilding it and not being able to use the car as a street/daily car lol
