CTS Turbo BOSS Turbo Kit

[Spawne32]

If they don't have an option on tuning for the ZF 6 and 8 speeds, ill pass on this. I cannot afford to replace a 7000 dollar transmission.

In terms of reliability I think the 6 speed will be just fine the torque isn't near as much as an k04 and it handles that fine and torque is what makes shit hit the fan

I'm saddened it has an internal wastegate but still a cool kit

Although I think valve springs and a tcu tune to 8k rev limit is what this thing needs. Take full advantage of that big turbo

That's the thing though, we would need both a custom ecu and tcu tune for this project, which either will A)take too long for the community/tuners to make, or B)never come out

I mean I'd love to take a crack at it myself but I sadly don't have a bench setup to gain access to that part of the bcm

Manual swap with used parts is about $1500.

CTS posted this. Seems United motorsports are getting their hands on these kits. They'll probably have some experience when it comes down to tweaking it for the b8

Pretty sure this means United motorsports will have an off the shelf or something ready to use when these kits come out.

Thanks for posting the latest news!

There are a ton of Mk7 GTI, Audi A3/S3 cars currently on the road running BOSS kits without issue for over a year now. Most of them are making 400-500 awhp and most were tuned by United Motorsport. I posted about that in this thread back in February.

Our B8 setup will likely make less power due to limits of ours cars' fueling systems. I believe injector upgrades will be common with these turbos on our EA888.2 engines. Either way, my suspicion is 370-420 awhp and UM will undoubtedly have the most refined tuned and be the one to go with.

I'm at a point where I am close to the failure rate of the oem injectors. Already had one which started staying open which led to hpfp failure. A little injector refresh won't be a bad thing.

If most k04 setups have issues poking 300awhp without e85/meth. I'll gladly take a mild 350awhp on 91/93 if the kit ( the smaller 2867r) offer some decent low rpm torque for daily driving. If there's room to grow, that's all that matters, that's something these k04 don't offer.

I'll go spend some time looking at the dyno maps available for 2867r builds for the ea888 gen 1. If I recall, I've seen some fairly interesting torque curves. ( Was looking at the difference in the turbine a/r of.64 and.84)

Still need a new clutch

I feel you. I am running the Southbend Stage 2 Endurance kit so I'm good to go in that department. Can't wait for this kit.

Or I can just go buy a faster car.

You're lucky. I'm still on the stock one and I feel like I have to baby the thing. I never even attempted dropping the clutch. how's the grab on the stage 2?

Really good, my tune from APR has a hold feature and will hold the revs at 5500 rpm when in gear and the clutch engaged. I can then dump the clutch and it grabs instantly, even has a little bit of wheel chirp.

What? Never heard of that. What stage are you? K04? Or stock turbo with stage 1/2? Was that feature added for you car or everyone has that? Maybe it's a feature only available on people with upgraded clutch??

Makes me want to go try it out hahahaha. My clutch will definitely slip tho. I'd have to let it slip a bit and then let it grab. Not like you with drop I suppose..

I feel 5500 might be way too high to do a clutch drop overall...

I think you can't Rev past 5500 unless traction control is fully removed. Without apr, I think the Rev are stuck at 4,000. It most certainly isn't a feature to hold rpm... But eh.. Maybe you're talking about something else.

It’s a special tune APR made for me when they were releasing the 3.0 version. It’s still buried on the forums somewhere haha. I’m at Stage 2+ holding out strong until this kit is ready!!

I used to do it with the stock clutch before it gave out. It wouldn’t grab right away though, slipped a lot haha.

Here's a screen shot of the email conversation between me and the APR Engineer on this feature. Reach out to them and see if they can hook you up. It feels really good to do a proper AWD launch.

Factory cars have a 3500 rpm redline while in neutral. The way to get around the rev limit is to put the car in 1st gear, press in the clutch and turn off traction control. That'll let you rev to the normal redline.

Yes thats my A5, and it will be running a UM tune

[kradgsxr2]

Any updates on the B8 Kit?

[blbroo]

I wonder if this will ever really launch. The volume potential for our cars isn’t huge.

I’m thinking of moving to an s3 to go boss 600, but would keep my car if this kit produced great numbers.

Get an MQB car if power and speed is what you want. I️ drove a stage 2 S3 once and it makes my Allroad feel slow

It’s been almost a month!! Any updates?

[Mina08]

Guys

been reading through the thread, any updates. My motor is reaching the end of its life, i want to keep the car as i love the B8 Avant look, and also have the chance to buy a brand new motor from Audi 2.0TFSI 211hp(the latest spec) for a crazy low price. So i was looking at this kit from CTS, my only worry is i have the 7 speed S-tronic (recently serviced), will it hold up? i am looking for around 350+hp. i will get a tune, HFC, larger intercooler, and intake if i go with this kit.

[A4 Centaur]

^ I think if you don't do a lot of launches and hammering on the transmission you should be fine. Fresh fluids and get these two parts connected and let us know how it goes!

[B8_Dude97]

This was the last update from CTS about a week ago.

Thanks for that, great shit load more to spend, dropping the trans. Now i am a little nervous about this, if to do it or not.

You will NOT need to do transmission hardware upgrades for the power you want. You said you want 350hp, so you'd want to get the BOSS500 kit and run a mild tune. The turbo will be capable of more power, if you want more later.

Your trans is the same as the B8 S4 and is perfectly capable of handling 350-400 lbft of torque. What I would suggest is upgraded software for the transmission. That will make it shift faster and smoother with the increased power levels. DSG is capable of handling that per, but it will be jerky if you don't have better software running it. Trans software is just as easy to install as engine software.

Any updates on your red A5 and BFI doing the UM tune on a BOSS kit?

i was hoping so, thanks

Getting there!

[Ronb8.5a4]

I'm excited for this kit. Can't wait!

[SleeperCar]

I’m still unsure how 500hp is claimed, I’d be curious to see logs. Also New forged internals seem like a must, and that can add up pretty quick.... also new fueling system too.

I’m beyond excited as well, but, will this be ‘daily-able’

Let's just see one.. any b8 run under a 12.1 in the quarter... If it can't.. then k04 on flexfuel e85 vehicles are king!!!..
Really cts has a development car to really put this to the test...

The boss kit is somewhat mature on the VW platform, golfs, GTIs, etc. our B8s share a lot of components with the European VW market (like fueling) and those guys are running the BOSS kits with stock internals. There likely won’t be a flex fuel option though since Canada doesn’t get E85 and the tune is going to be written by United Motorsports.
