aeb k04

[zakx]

Hello, A friend of mine is looking to k04 his aeb 1.8t. He is looking to go on stock internals and is only looking for about 250 at the wheels. What injectors, fpr, maf, tuning do you guys prefer?

I find that a little hard to believe. Check Audiworld/ Vortex.

I just got done reading your build lmao. I've already got everything figured out here with this. Talked to a tuner already

He might as well just go for 300 at the wheel. Why not?

[Dan[FN]6262]

400, shoot for the moon

I'll play nice.

250 at the wheels is a mondo mondo unrealistic goal on pump gas from a k04. He should expect 200ish at the wheels from a well sorted k04 car; meaning proper charge cooling, fueling, exhaust, etc.

I really find it hard to believe you've searched and found little. What exactly are you searching?

What Believer said.

If your friend is serious about a consistent 250awhp he will need a GTRS with decent supporting mods, minimum.

A strung out mixed flow Frankenturbo setup should get around there too. But might cost more to achieve 250awhp with a Franken than a good used Eliminator setup.

But the Franken setup would have a wider powerband

If we're ruling out E85 and a custom tune (since AEB), you're definitely right. But IF E85 is a consideration that quickly changes. My car made 203 awhp on E85 with the stock turbo (as you guys know).



Also, a K04-015 made 256 awhp on E85, so it definitely can be done.

Quote from Motoza Post:

This may be the most powerful K04-015 we've ever done! 293 AWTQ and 256 AWHP on an 02 B6 A4 Quattro
Kevin Hardesty has been awesome to work with. We've been helping him with his standard K04-015 running e85 with MTC, a front mount intercooler, stock MAF housing/sensor. He's also running an APR 3 inch turbo inlet pipe, an APR carbonio intake, and an OEM 710 diverter valve with the EV14-550cc Injectors.



Of course this is with many revisions with Motoza on the wideband type ECU, but it can be done...

Edit: If he want's to buy the same 550's used for the K04 dyno, I have them for sale in the classified threads

[Believer]

Yea E85 kind of changes everything. I assumed the OP did not have this in mind.

To Dan's point, to achieve these power levels from K04 frame turbos, they snail is being strung out. That doesn't lend well to longevity, in theory. My mixed flow FT at 24 psi max tapering to 22 with 10k miles on it (not all at those boost levels) has already developed what I could consider decent shaft play. Just food for thought.

Definitely a good point. I just thought it would be fun to add the E85 numbers into the mix just for gee-wiz. As far as the shaft play goes, that stinks. Sort of makes me feel good about having a 22psi max right now because of stock rods.

Oh for sure man. Its definitely a good contribution to show what e85 can do (bastards!)

Haha thanks. Yeah my car is almost ready for the dyno (feels great). Waiting on the test turbo blanket (my extra turbo is arriving at PTP today), and it will be ready to go! Hoping for 275 awhp or so with the intercooler sprayer. Dave gave me a more aggressive tune I can use if I come in under 275 tq lol. I may use it anyway...

And then it will be time to hit the track some time in Sept.

Yeah, I am super blessed to have a station about 4 miles from me (Shell). It's $2.29 a gallon. I don't know if I'll ever switch back to 91 lol. Such a huge difference. I have enough range to do a round trip to Phoenix without having to refuel which is nice (although Phoneix had lots of stations too).

My cousin's family owns a bunch of convenience stores that sell Shell fuel.

I've been badgering them for years to carry it but they say that you need different tanks or something.... IDGAF DO IT! lmao.

I actually found a place that sells it 20 minutes from me, if you enter the facility on the back access road that is meant for employees. But the employee parking lot is fenced off and the station is not accessible by vehicle.
So you have to access the rest station via the turnpike, and only from the west bound lane. I'd be heading east bound going past. So fucked. So I would have to drive almost an hour away, hop off the turnpike, then back on the turnpike to head home for almost an hour, and before I jump off the turnpike to go home stop at the rest station and fill up. That's stupid.

My cousin offered to sell me a 55 gallon drum of E85 in lieu of installing a pump. He never offered that before and I am game. So I think I'll just keep a barrel of it around for the weekends and still run regular 93 throughout the week.

[B5nDisciple]

Nice! Sounds like a plan:)

this is the same exact situation for me except its only 5 min if i take the access road.

United Motorsports' website is currently under construction, but I'm pretty sure they do a stock turbo E85 tune. And I bet some of the other common tuners could do one as well.

AEB owner chiming in. Borg Warner K04-015 w/ GIAC PC-16 and all supporting mods (on my sig) for my B5 estimate good for about 210-220whp on 93. Makes for a nice DD setup to go stop light to stop light. Had the pleasure of owning setup for 8+ years and 70k miles now and still running strong (knock on wood). My new B8.5 S4 would put bus lengths on it though lol, but it's definitely still fun to drive around.

OP, just search there are a lot of threads on K04-015 + AEB's in the B5 Forum/Sub forums.

Thanks for not bitching like everyone else lmao. in colorado we dont have 93 unfortunately we only have 91 but we do have e85 as well. Would you mind telling me your supporting mods?

South Bend Stage 2 OFE Endurance Clutch
ABD Intake w/ Blinktek heat shield

NGK BKR7E gapped at 0.028"

OEM DMFW

And a bunch of suspension and drivetrain stuff that are nice to have but not required for K04 setup. Although, shameless plug a solid Rear anti sway bar is amaze balls bang for buck mod for the b5

thanks for the list. Just a couple questions.. whats a DMFW, when you say oem maf you're talking about the stock one with housing or bigger housing? and is a fmic needed? or can we get away with using the stock one?

Dual Mass Flywheel and Stock MAF sensor/housing.

FMIC is not mission critical but setup performance is dictated by properly matched HW/SW. GIAC recommended keeping IAT's below 50F. If deferring FMIC, make sure to log your IATS as the stock SMIC sucks at its current location/cooling surface area ratio.

How are you supposed to keep IAT temps around 50F when ambient temp is above that? GIAC really claims that? Do they not know that a good FMIC will bring charged air temps to near ambient temps, but you will never reach sub ambient temps?







EDIT:


I don't see that posted on the website page for the AEB software?

You are correct. The 50F recommendation was probably not an absolute, rather a value given during a certain test condition or some relative value. Keeping IAT's close to ambient would be a better rule of thumb.

For my understanding of air to air HEX, efficiency matters. I think it goes something around Efficiency = (Tin - Tout)/(Tin-Tambient). At increased boost (relative to stock) one would think the stock SMIC is out of its efficiency range in keeping the charge air below an atrocious number above ambient. Not to mention the side location is not adequate for convective cooling purposes (b5 A4 doesn't have nice 2x IC shrouds like the b5 S4).

TL;DR 50F not absolute, recommend a more efficient IC when running higher boost (relative to stock) to keep IAT's close to ambient.


*could have sworn it said some temp on the required HW, now it just says intercooler

[Dan[FN]6262]

The stock SMIC is hardly enough for the stock turbo at stock boost levels haha, so you are definitely 100% correct about needing a FMIC.

The stock unit is seriously underwhelming. I'd upgrade it with a cheap ebay unit if I had a stock car as a DD. Keep everything else stock haha. God, is the stock unit bad.

[Believer]

Shameless plug: I know someone selling an Apikol SMIC for substantially less than new. PM me if interested.
