B8 Ko4 owners follow up thread

[Spawne32]

Yeah that was sarcasm if you couldn’t tell

TBO ended up refunding me for the wastegate after a debate and them not understanding the concept of preload

lol I can't tell what's what on this forum anymore with EA posting. Half the shit he posts is a joke.

[EvolutionArmory]

Actually it’s kind of confusing

FMACVAG06 is for oem k04’s

FMACA4L is for the Borg Warner style k03 not the ihi or the hpa k04 - intended to be used with retaining clip rather than the 2 nuts

Ihi uses a different bracket all together

FMACA4L is the one that was too short


Just looking at their catalogue should show how different the brackets are between the turbo models. They don’t really list rod length or travel

It is confusing. Maybe I’ve just been lucky with buying 2 K04’s that just have the correct style wastegate to run properly.

All I know is that Nano will never be able to run right with the wastegate he has in there now.

He need 8-10 PSI crack with 10mm of travel. How he gets there is up to him to figure out.

I think its pretty cool that we are making the same power and running the same times as APR100 file advertises while only on pump gas :)

Not sure you can say you’ve tied apr 100

I’m only one person with a time in less than ideal conditions with a very high mileage b8.

Shane’s running 12.2-12.3’s

That’s why ea says you’ve tied the time from 5 years ago

[Traptalk]

To be fair tho I don’t think spawnee has set the community back 5 years. There has been some good info and some misinformation passed around tho not all which can be blamed on spawnee.

There was an initial hesitation to up the wg pressures

It’s all been a good learning exercise however and their heart and spirit is in the right place

I just don’t see there being too much of a point anymore to go thru hours of logging and beta testing just to tie apr or ideally to be slightly faster but that’s up to everyone to determine for themselves if 6 months to a year of trial and error and logging is more beneficial than getting a one time flash and being done with relative ease

I really don’t think there is some crazy abyss of power that’s not being used that’s able to be extracted just a few psi more of boost

The only real Advantage I see is to finally be able to
open the door up to more options than k04s and bootleg k04’s

Custom tuned or apr the best these cars are doing are 12 second quarters. I don’t see anyone running 11’s without at least switching to full E85 with supporting mods and software


At the end of the day those these are old slow cars and you’re going to get gapped by any of the newer 2.0T models

Stage 2 a3 would probably gap us, stage 2 s3 would wreck us, mk7-7.5 golf r

The k04 is not an impressive turbo and the b8 just isn’t a lm impressive car

I have the oldest and slowest Audi in my local friends group. Sitting in a stage 2 s3 for launch and then coming back to your b8 will make you feel like everything you did that isn’t buying a better platform as a waste of time

I’m pretty burned out on this platform. It’s a decent looking car but that’s really about it

For a daily it’s not bad power wise and will make a decent winter beater/work commuter but none of us should really be as petty as this community is and we definitely shouldn’t be trying to Dick swing or argue about being faster when we are all fucking slow

What I really didn’t care for was the advertisement and talking like it’s a golden solution for every problem that comes with b8 ownership and tuning. There’s no need to try and recruit people like a pyramid scheme.

Posting your results and personal progress is one thing but the active recruitment just leaves a poor taste in my mouth or making claims about it being soooo much better with no real proof behind it to back it up

I’ve been getting really jealous of the newer models my local friends have now and how much faster they all are than me without having to go stage 3, get a custom tune, or ever even have to do a data log

It’s all so much more effortless than it is for any of us

So I’m starting to plan for what’s next and I don’t expect to give this car anything more than the regular maintenance it will need to stay on the road.

Envy is a bitch.

Your times aren’t the reason why.

People running 12.6-12.5@105 or 106 on APR 93 V2 when it first came out is why I said that.

People running 330 wheel on 93 5 years ago is why I said that. Had nothing to do with your times bud. If you change your TCU shift points a little you’ll crush it though.

These guys are pushing 5-6 PSI more and making less power or are only on par with an OTS tune.

And if they do beat those times on a lucky run, it’s by barely even a tenth. What’s gonna happen in summer when DA goes up?

Slower cars or worse, Kaboom.

Yeah definitely still have work to do on Amax shift points

Haven’t had much motivation to log or move forward tho 😂

Maybe one day I’ll care again

[Iceman502]

Data as promised, plus me working backward through some of the other logging parameters. Since I don't have a draggy dongle, but now have a script that will be almost as good (assuming minimal wheel slip), I can estimate a 0-60 time. BB's tune smokes me down low, but we start to equal out at the top end. From here, I just really need to get on a dyno. More importantly, it numerically shows that the K04 flows just as much air down low as a K03 and when set up properly, is not laggy by comparison.

Nobody ran 330 wheel on 93, and certainly not on a B8. Every one of those 300+ numbers were always B8.5's typically with methanol or some combination of E, with the highest numbers being those running the APR 100 file. I had those discussions years ago before you even started your antics here. BB's car has produced the single strongest dyno ever posted on this forum on pump gas on a B8 before and I challenge you to find a post on here with someone showing otherwise that isn't a B8.5 and isn't running some sort of fuel additive or alternative fuel using nothing more than an OTS file. This is exactly why some people like A4X have the prevailing theory that the K04 is a waste of time and money, because most of them barely crack 290 wheel unless they are more heavily invested in fueling mods and more aggressive tuning.

Edit: And I think it's important to note since this is now the running joke, BB is making 319/369 with nothing but a tune, a K04, intercooler, and HFC. He has a bone stock exhaust, bone stock intake manifold, and bone stock air intake. Anyone who had previously cracked 300+ had every possible available bolt on they could buy.

[Iceman502]

There is some estimation involved with the above figures simply because of timestamp precision, but since a 2007 Jag XK coupe could do 0-60 in 5.9s with a peak acceleration of 4.5m/s2, that gives me some confidence in my plots. If I adjust my time step, my acceleration estimate increases to 5.3.

https://hypertextbook.com/facts/2001...rricella.shtml

By logging a 0-60 and maybe quarter-mile pull, I should be able to refine this a little bit. This is an instance where VCDS may be better than the IE logger because I don't need so many parameters at one time, and get larger time steps. IE is down to the millisecond but doesn't actually print the value to that precision. When working with the numbers, I could have one-tenth of a second split into 14 values, or up to 19. The inconsistency makes it a bit more challenging.

And BB is doing that on 93oct. No water or meth or E85, straight up 93oct. There's your kaBOOM

[Spawne32]

If BB continued to mod, and added methanol or E to his setup, he would single handedly have the highest power production B8 we have ever heard of on this forum, no doubt about that. We have only begun to touch what his car is capable of with just the K04, and we still have not even exhausted possible CHRA changes to give him different compressor and turbine wheel combinations.

[EvolutionArmory]

All 3 pulls are higher HP than BB. Only difference is a cat back and this guy isn’t running 28 psi to make it and he didn’t heat soak his intercooler after the first run because he’s not running 28 PSI on a turbo designed to run 14. 🤣

2012 A4 in 2016. 5 years ago.... Not a B8.5.

330 WHP. And his power kept going up after each run. Not crash and burn half way through due to heat soak.

I know. It was the fan’s fault.

Because he’s been pulling 300 g/s+ since before hpt was in the picture

There is some validity with your point since they both have the original CTS version of the K04, and a slightly different internal volume in the casting could be allowing them to produce more airflow at high rpms. We've covered that on other threads but worth reiterating here.

[flowhigh]

Wow, you guys are really taking the wastegate warrior stuff literally. This debate has been going on for a while

...I did want to ask if any of you running the Ko4 on your daily and how's that going?

The wastegate is the most important thing to set a turbo up right. It makes or breaks your performance.

Yes, that's true I've wrenched on a few. I was using a pun regarding all the CHARGED banter.

One thing's for sure IE is doing a great job of marketing. I am thinking considering their cat+downpipe if I can land a apr stage 2 tune. If not I may consider the stage 3 k04, hence my question on daily reliability.

IE is not a bad company. Their products are on par as good as APR's products with a lot of development on the hard parts side. It's their B8/B8.5 tune that really sucks hard. I recommended IE myself to my friend who just bought an A3. I flashed it today and it went from running mid 14's to mid 12's with nothing more than the stage 2 and the DSG tune. No additional mods other than their intake and turbo inlet, which was very well made. The beef has been, and continues to be the fact that nobody wants to pay $800 for a tune for a turbo swap car to run mid 13's. Nobody.

I’m tempted to flash my wife’s A3 8V with IE’s stage 1 file but I don’t think she’d appreciate it 😒

It would probably be as fast if not faster than my Q5.....

He ran a easy 13.5 with the stage 1 low torque file. Both of them were very very smooth, I doubt she would even notice until she punched it getting on the highway or something and almost rear ends someone.

Are you guys running upgraded brakes/rotors? On stage 1 my brakes already aren't enough. I find myself doing the light pumps a lot to slow me down faster.

I just have a feeling with with the stage 3 RS3 K04 I'm gonna get myself is some trouble. I'm E85 and even at just stage 1 it's off the chain.

I already blew by two cops this week over 60 mph, one was on the median on his cell phone and didn't have his radar (I was doing over 70 point blank) on since my Uniden didn't chirp at all, he didn't even look up. The other was parked directly perpendicular to my line so he couldn't get a reading on his dash mounted K band - just an FYI for those of you that didn't know.

Also considering the longevity factor.
