B8 Ko4 owners follow up thread

Looks great! I'll be getting the ECS piping kit since my mod bug runs deep. The piping kit should work fine since the APR FMIC is meant to be used with stock sized piping. What I'm concerned about is the ECS pipes come with an OEM turbo muffler delete which also ups the piping size, but with the K04 there's no need for the muffler delete, so how does THAT connection work. What's everyone doing? Just a silicone adapter?

In for this answer as well.
I assume it's just going to be another coupler but interested in other creative ideas.

Yep, I just put my K04 in and had to get the adapter to go from the small 1.75" K04 outlet to my 2.5" Eurocode hard pipe. I posted the link to the part in my build thread second from the last page if you have the same sizing. If not you can choose the size you want and it's a good quality product for a good price.

Edit: I did cut the top part down a quarter inch to keep the pipe from being pushed down into the bar below.

The KO4-R comes with the outlet on the turbo that is the same size as the OEM K03 outlet. No pipes needed.

I have the APR FMIC and I am using all the stock hoses, except for the sound delete pipe which is metal.

Awesome, thank you! Link for the lazy. Even comes in red because racecar.

Right, which would be fine if I were sticking with OEM hoses, but wanting larger aftermarket hard pipes adds an extra wrinkle to this adventure.

[A4 Centaur]

Yea, you are right. I used to double up clamps after blowing hoses almost weekly on my A4 Jetta TDI.

I had huge pipes and varying sizes of both hard pipes and connectors.

Hi, can you give us some feedback and mayb dyno numbers after you install the k04R from JHM? I'm looking to go the same route as the APR kit is kinda pricy

[A4 Centaur]

No dyno yet. Gotta do timing chains first.

Check my build thread

I have to to do my timing chain as well, I'm at about 71,000 miles. I was planning on doing it at 80K but since going K04, I'm thinking sooner than later. Where has everyone been getting their kits from?

what tune are you using? i notice that you have CTS k04 in your signature. have you dyno your car yet?

I'm using the APR 93 ko4 tune. Not yet, I'm itching to dyno it though! At some point I'd like to run meth and do the 100 octane tune.

If you have a B8.5 you don't need to. Revised tensioner. B8, yes

I'm gonna do ECS I think

[ASheppard]

I'm sure this has been asked before but does the engine need remapping right away with this upgrade or can it be done at a later time once installed?? Any harm in installing the K04 then doing the software a couple of weeks later?

[A4 Centaur]

No, you can run the K03 files with the K04. Just don't expect much, but it feels much better after the installation.

Also, it seems that some adaptation occurs after uploading the new K04 file. Takes about what 50 miles?

Who has some feedback for the JHM K04-R? I know there are at least 3 guys running it now

I'm running JHM HFC and JHM K04-R with UM K04 tune, have not dyno the car yet, but from my experience I don't think this set up can past the 300whp mark, somewhat disappointed.

Most of the k04 setups are going to top out at that 300-320 range. My loba lo400 was at 360wheel but it was at it very max output on 28-30psi

I would keep it out of boost until remapped.

Possibly disappointed because of the UM tune? I think the general consensus is that the APR K04 tune is the strongest.

I don't think too many people on here run UM.

Foe example with Unitronic, we know that tune has much less (clutch protecting) torque.

That sucks I had high hopes for this k04 I guess I'll just have to save up more for the cts one. Since you live in so cal did you get your UM tune with James at 4 seasons?

In all honesty, I think it was me, I wanted something a lot faster, the tune and the hardware are in no mean under-performance, I think i might have to try different route in the future. As for now, I'm going to dyno it first. So that i have a set numbers to base on.

It's also pretty warm out in CA the past week (at least for us) as we have had nothing but triple digits and today is going to be about 110F. Heat is a real power killer.

I don't have any experience with UM and their software. I know the APR Software performs very well with the K04 variant turbo.

Yea APRs software works great with the K04. Love mine. CTS K04 and APR. 322 whp/ 418 WTQ

My butt dyno says this K04-R is a solid 350 AWTQ

HP numbers as Slowone stated are probably 310-320 AWHP perhaps. Also, the B8 is a very heavy car which doesn't help with it sprinting off the line either.

I am doing the Fluidampr and changing timing chains this coming weekend, and though it wont add any HP it will be interesting to see what the dyno numbers are with my mods:

1. K04-R
2. APR FMIC
3. Fluidampr
4. APR Tune
5. Billy Boat Exhaust
6. 034 HFC
7. R8 Coils/ NGK plugs

In the May Issue of European Car Magazine, 034 motorsports had their S3 hybrid Loba turbo at 408 HP/ 382 TQ and an Audi TT with Spulen K04 at 324 HP/ 351

Considering the drivetrain losses getting above 300 to the wheels is impressive as your probably around 400 at the motor. On a FWD or RWD traditional auto we typically use 20% as the calculated losses but AWD somewhere in the area of 25%.

[A4 Centaur]

^Probably why the S3 got such high numbers? It is a Haldex system which has less parasitic drag from the driveline?

[AllroadCorbin]

Comparing different cars on different dynos is pretty useless tbh. Even the exact same model car and same model dyno. There's so many variables that can make shit different. The only useful comparison is the same exact car, on the same dyno, under the same conditions, with a different mod. Otherwise there's a host of different things that can make the comparison funky. Even tho the dyno I went to is a bit far away, I'll always go back to the same one just because that was my baseline

Not sure honestly because I don't know the makeup of the haldex system. It really depends on the amount of moving parts in the system.

That ^^^, and it has a different fuel injection system like the golf R so it's able to sustain higher power levels. APR told me that their K04 E85 TUNE on the Allroad maxed out the stock fueling. And The flex fuel pump flows more than the standard A4 one but even that isn't enough to breach 330whp.
I'm not sure the pistons and rods are the same either.
From talking with different tuners it seems the general consensus is the pistons/ring lands are good to 400whp in the 2.0T gen 3.

[slowone11]

My stock 2011 a4 lpfp is working perfectly at the 400wheel mark. It is the hpfp that can't keep up.

Which pump are you talking about? Makes me wonder if I swapped pumps, I could get more fuel and make more power on my 6MT...

Hes talking about the lpfp, but either way hpfp or lpfp, your limited on the tuning side of it anyways, the pump will only flow as much as the tune requests.

This turbo is only $1695 now on the JHM website. I could swear that last time I looked it was $1750.

I am about to splurge . Really would like to see dyno result of this turbo on the APR software!

The KO4-R comes with the outlet on the turbo that is the same size as the OEM K03 outlet. No pipes needed.

I have the APR FMIC and I am using all the stock hoses, except for the sound delete pipe which is metal.
