CTS Turbo BOSS Turbo Kit

[lettuce]

2) Slowone is not really comparing his current turbo to a K04... he's comparing it to a Loba LO4xx turbo he used, which is a highly modified hybrid K04 turbo that makes more power. The LOBA LO4xx is probably the closest turbo currently on the market to what these CTS BOSS kits will be. These boss kits and the LOBA probably spool at nearly the same point, but with the GTX turbos used in the BOSS kit having slightly higher top end power capabilities. These BOSS kits will likely be the absolute sweet spot for quick spool while still having top end flow for making power all the way to redline... that seems to be the consensus from pretty much everyone with these BOSS kits already on MQB/Mk7 platform cars. The people driving those cars have them as daily drivers; not project vehicles. And the Mk7/MQB kits are selling lot hot cakes. If Slowone had used a typical K04 he may not feel like wanting to go back.

Looking at Slowone's dyno graph of his Loba, and going off his experiences with it, it also seemed to me like the shop that tuned it, tuned it very aggressively, which is what led to it blowing after less than a year of use. If you overlaid his Loba dyno plot over a normal K04 plot it was basically identical in regards to spool time and decay, except when the K04 would level off boost after hitting around 23-25, the Loba kept rising. I think I remember him saying he was hitting upwards of around 30 psi.

There may be a little bit more overhead before hitting surge on a Loba, I'm not sure I've never seen a compressor map of one, but I'm willing to be that if you wanted to you could custom tune any K04 to do something similar, with a similarly shortened lifespan.

If these kits ever come to fruition, and are using the Gen 2 GTX-R turbos, they're probably going to be the best all-around option for our cars. If I could go with any one turbo it'd be one of these.

I'm surprised we havent seen twin scroll yet incorporated into anything.

When will this kit be ready for mk6 R?

Unfortunately no ETA yet but we're aiming for end of 2017

If this turbo kit never comes for our cars, I'll symbolically throw my keyboard and physically trade my car in for something else

I wonder how much that boss 500 is gonna be and how the hell were gonna tune it

[spin0rz]

Well. Seeing the gen 1 kit and what it offers lol..
That's the apr gtx2867r so similar to the boss500

The kit for the Mk7 are A3 8V cars cost $3,300. The kit for the Gen2 cars like ours might be a little more because of the large manifold, which isn't needed on the Gen3 engines. They're true bolt on kits, all parts included, hence the name.

There are already several tuners for these turbo kits. United Motorsport has done most in the US, and a couple shops overseas have done custom tunes. These kits will be capable of reaching the limits of our stock connecting rods. Upgraded rods are even recommended when pushing these kits to their limit.

I'm planning on putting a used b8.5 motor on my car, since I have oil burning issues and a bent valve but should I swap the pistons out also then?

What is the most our motors can take?
Sorry for the noob question.

It will be nice to see some options moving forward.

Pistons are not the weak point on the engine. Connecting rods are the weakest point.

That said, what breaks rods is high torque, especially at lower RPMs. A smaller turbo that makes 400wtq at 3000 RPM is more likely to snap a rod than a larger turbo making the same 400wtq but instead at 4000-4500 RPM.

Running the smaller Boss500 kit will probably be fine with stock internals, but a rod upgrade for either kit would be the safe way to go. If you will already have the engine out of the car, it's a no-brainer. Rods are pretty cheap too.

Thank you for all the info now time to just save up a bit more

I wish there was a cts loyalty program as I've put their k04 on less than a year ago

[KanjiVirus]

It kinda sucks that they aren't releasing their own tune for this, it would be cool to see what the 6 speed tiptronic can take but no one will tune those transmission

^A former co-worker has a B7 A4 2.0 with an APR Stage III kit. He is still hammering it today and it is going as strong as the day he installed it back in 2011.

He lives in the CoS area, and its all black murdered out with 18" wheels and a 6 Speed Tip. Said he only needs to change fluid every year or so to keep her strong.

I would have bet my paycheck that he would have blown both engine and trans by now. Talked with him earlier this year, and he's beating on it and racing Subi's around like a mad man.

He thinks he's at 350 AWHP and I have ridden in it, and its fast: https://www.uspmotorsports.com/Engin...SABEgIlxfD_BwE

I don't think he's on the forums, but here is a list of some of the B7's that have done this kit: http://www.audizine.com/forum/showth...ge-3-Roll-Call

I wish we could have seen something like this for B8's by now, but I am pretty happy with the K04-R thus far.

How did he fit a kit meant for a transversal engine on a longitudinal?

I wonder that too from time to time. Why does our platform leave a lot to be desired in terms of power? There clearly is demand, at least as much demand as there was for the B7.

Does anyone know of companies that will even try to tune automatic transmissions for this turbo kit?

Not unless you got money to wave in their face.

Okay "quite easy" is a stretch. First you need a tcu dump. Only two ways I know how to pull that on our cars and one option requires pulling the transmission, other is through the bcm module/canbus.

Tcu dump can then be attained through older methods of flashing like the dealer does and obtain a bin of it. Then you'd need to actually tune it and then flash back the bin to he eeprom.

Tldr: Possible(bimmer guys did it,same tranny) however it's not something that can be done overnight

Even if CTS had their own tune, I'd still go with United Motorsport. CTS does not specialize in tuning; just in hardware design/manufacturing. That's the way it's ALWAYS been. That's actually a benefit because it allows full-time software companies (who specialize) to step in and make not just a single tune, but multiple tunes catered to specific owners and varying overall setups. UM has been doing most of the tunes for the CTS BOSS kits, and other companies have tunes in the works. That is a benefit to customers, because it offers choices and competitive forces keep prices lower.

If you look at the Facebook pages for CTS and United Motorsport you'll see over and over about specific cars that are running the UM tunes with REALLY good results.

Only problem is no one tunes the automatics, and I know the 6hp28 in pre facelift models can't handle that much torque, it's still good for some bit and can definitely handle more than a k04

That's not a problem for all of us.

Someone needs to make a "High Horsepower w/ Auto Transmission" thread. Every 10 posts in here someone brings it up and clogs the thread. This thread is about the CTS kit; not auto trans issues.

[Zach L]

I wonder that too from time to time. Why does our platform leave a lot to be desired in terms of power? There clearly is demand, at least as much demand as there was for the B7.

The EA113 engine is stronger overall than the EA888 Gen2 in our cars. The EA113 has also been around for over 13 years at this point. Our B8 engine has only been around for about 9 years, so it's not as far along in the aftermarket product offering cycle.

Another reason this kit is not available is because products are always developed for the GTI and other transverse applications first, since there's a much larger potential customer base and more demand. Kits and tuning for the A4 always take longer to come to market.

Technically, you can post anything you want in any thread, and I can hassle anyone in a thread. Neither would be good for the forum though.

What is good for the forum is posting about what a thread was created for. Addressing the auto trans issues is important, but it's not specific to this turbo kit. There are already custom turbo kits people are running right now, and there will undoubtedly be more big turbo kits available in the future than just this CTS kit. I agree this is an issue that needs to be discussed - there should be a thread and I probably would have made one already if my car had a slush box. It'd be helpful to you auto guys as well if looking for transmission related info not having to dig through various turbo threads.

Makes sense. I guess we just have to wait for this kit to come out for the B8. Still have my doubts if it will be released.

This is true. So glad I got the 6MT where we remove the transmission from the equation as one of the limiting factors.

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