Frankenturbo F4h-l Audi A4 Quattro

[cdn20valve]

I just ordered my kit,. I'll be installing it on my B6 A4.
I'll keep adding info to this thread, with the progress of my build.

I'm planning on staying with APR for now. I currently have their 1+ software. I will upgrade to K04 software, and see how it goes from there.

I have water meth on this car already, and catback exhaust.


*****UPDATE #4***
Got unitronic 2+ chipped and finally had a chance to re-dyno.
Here we go...


*****UPDATE #3 Dyno results



*****UPDATE #2: Turbo Comparo!!
*****UPDATE: Pics on page 2

i doubt a normal k04 file will work properly

[cdn20valve]

We'll see. I'm hoping it does.

I'll definately let you all know. I'm convinced that this setup will be perfect for a DD. Better/more power up top, and still regain torque down low.

[Dr. Pepper]

how much more hp and tq will this net you over an aggressive K04 file?

[Capt. Obvious]

You bought a turbo for your car from a guy named "Slappy Dunbar"? Did Adam Sandler open a tuning shop?

You are a brave soul.

Lol. I don't care if his name is cow balls. Product seems good, price is excellent. If it works out, then we all win. No?

This is a perfect solution for those of us that need a DD A4. As soon as I receive it, I'll install it, and let you all know. I also plan on getting it dynoed etc..

I'm still not sure on software. APparently Uni is putting software together for this turbo using a larger maf. The kit comes with a new tip pipe (as the turbo inlet is too big for the oem hose). The kit's TIP has a 3" maf size as well, for upgraded mafs.

I just need some in fo on the APR K04 file for now. ANyoen know what requested boost is on the b6 k04 file, above 6000rpm?

[Capt. Obvious]

I'm actually very curious about the results you get with this setup. The pricing is great and the advertised results are pretty good, and the kit looks like a pretty nice setup. I'll be watching this.

[Killerteve]

I don't know if APR would be the best way to go. You might be better off going with Revo since you will be able to adjust some settings with the SPS 3 which might be helpful since this isn't a typical turbo the file is tuned for. As far as fueling goes, as long as the flow rate(lb/min) of the turbo can be matched by your injectors you shouldn't have to worry too much about leaning out. You definitely need to do some logging before anything is safe though.

What do you mean? I daily drive my car and it drives perfectly fine with a 30R and built motor and what-not. Actually gets better gas mileage on the highway than my car did when it was bone stock.

[Turbo_Whip]

mtm and dahlback have software for a special modified K04 variant turbo, maybe that would work.

is the $979 includes mani and dv or just turbo?

My car is a great DD, some might find it a little loud though to drive everyday, i like it though

this turbo look intresting and i'm deff gonna bookmark this but i'm more interested in the mani they had and if it's any better then 034's since i've been playing around with the idea of swapping my stock mani out.

[cdn20valve]

incl. turbo, mani, tip and new dv.

[EBG 18T]

The APR K04 will not be the best option for that modified turbo. It is just too mild of a file.

Also the idea of buying a modified BW turbo from a non-authorized BW rebuilder is sketchy to me. Actually is that even a BW turbo or one of the chinese e-bay BW knockoffs?

it might be Blouch man..hehe.

[EBG 18T]

atleast Blouch is an authorized BW service center.

If it was then a bad deal at all for turbo, mani, and dv.

[EBG 18T]

If it was then a bad deal at all for turbo, mani, and dv.

never said it was a bad deal. it appears to be a steal.

just seen in person 2 of the e-bay k04's (knock-off's) before and after they failed. It appeared (i am no expert) that the bearings felt subpar (not smooth) and the machining (aka porting) was not even. after seeing these i didn't feel confident buying anything other than BW product (person opinion)

I have never seen a frankenturbo and do no claim to have an experience with this turbo.

I selected Blouch due to the fact they were an athorized BW center and had a very good reputation. Unfortunatly the Blouch will cost more than everything from frankinturbo.

[cdn20valve]

Well, i'm havin second thoughts about the apr K04 software. After looking at this dyno on vortex, there seems to be a lean spot at 3500rpm.

Granted this is a transverse 2003 GTI 1.8t, frankenturbo F4h-t. with APR k04 tune.

I concur.

Gas mileage is way better and driveability is a lot better than the K04 setup I used to have,

[cdn20valve]

That's great that gas mileage improves with a BT. Does it improves in the city too, or just hwy? My B6 is a 90% city car.

Plus I need low end torque (less than 3,000rpm) in the city. I need to take off from light to light, and beat the minivans and V6 camcords to the next light without downshifting, or revving to 7000rpm, because frankly, where I live, that kind of high revving = stunt driving, and the cops will yank my car of the road. It sucks. I know. BUt this turbo fits the bill for me.

Now back to the discussion at hand. You guys think that the 386cc with APR 1+ tune on a B6 will run lean like the mkiv dyno I posted above at 3500 with a larger turbo?

Yes the apr file is very conservative and is not a good option for this turbo.

A k04 will still be close to minivans and other appliances

These modified k04s and k03s are known to have a short life expectancy, but maybe the frankenturbo will be different from the others. The idea of modifying the k04 is not new, read up on all the reviews and issues.

MTM and Dalhback racing have files written specifically for the modified k04, if you do go that route use a tuner that has a file for that turbo.

[cdn20valve]

A quote from Alex from Unitonic on vortex. Software is on the way.

...

I saw the kit myself and i can say that i was impress with the quality.
Sorry slappy, that mani and turbo is glowing red in our engine dyno room!

i then asked Alex about the B6 file. His reply:

...
No worry, finally this thing is running and we have almost all engines inhouse.
Now we move forward and let me say fast forward like working on week-ends for you guys!

Also, I'm told by Doug, that the new TIP is completed. Pictures are up on his website. http://frankenturbo.com/F4h-l.html Just scroll down a bit to see the TIP etc..

[EBG 18T]

The catch w/ MTM & Dahlback is they have propriatary injectors in they won't usually sell the software with out the turbo/injector/software kit. Plus getting file updates out of Europe is a PIA.

A quote from Alex from Unitonic on vortex. Software is on the way.

Sound like you will atleast have access to some type of file to support this turbo. I will be curious to see some data logs once you get this going.

[b6onboost]

If APR K04 software is running too lean on that hybrid turbo I would guess that APR 1+ would as well. The 1+ file pushes a little less fuel as the K03 flows a little less than a K04. Now, can 386cc injectors properly support your hybrid turbo, probably, but you'll need a proper tune/fuel map.

Now back to the discussion at hand. You guys think that the 386cc with APR 1+ tune on a B6 will run lean like the mkiv dyno I posted above at 3500 with a larger turbo?

[doublezero30]

so wait, for about $1200 you get:

-turbo
-manifold
-TIP
-DV
-assuming all lines and hardware also?



that seems too good to be true. and this is a modified K04? or more-so a GTRS?

it's crazy cheap.. I wonder what the overall quality is really like? it looks good in the pictures on the website. I also wonder who does the balancing of the wheels and how tight the tolorances are. From talking to a couple turbo builders back in the spring the proper balancing equiptment is $25k+ the machining equiptment.

But the biggest variable being software is not out there. Either folks will have to sit an tweak a existing file or spend the $ and do a custom tune.

I have a feeling though that the people that are looking at the price on the hardware aren't going to want to spend the $ on a custom tune.

A Unitronic tune will probably adapt just fine to make that extra power. You could also use unisettings to adjust until you get the power desired

[02B6]

op - cant wait to see the work in person. i'm close by.. good luck, Ill be keeping posted to your progres

The work? Lol. Installing a turbo is not work. Want to see work, no prob, you can come see my B5 quattro TDI swap or my mk1 cabby 16v on standalone...

But I know what you mean.

[Matt Devo]

did you look at/compare the compressor maps on that site? there's no way a file optimized for the K04-15 will be able to "adapt" optimally to the F4h-l. That's almost the same as saying a GT25/2x would adapt to a K04 tune.

[EBG 18T]

Sure. Ok.

Anything can be adapted. But that doesn't mean it is optimized.

[doublezero30]

so from what i understand then, its just a hybrid ko4? which probably wouldnt really give you much more power than a regular ko4?

[texasboy21]

just a little more, but not the same amount of power as a gt2x or gtrs turbo

[cdn20valve]

Guys. Not as much power as the GTRS obviously. However, I believe this turbo to fill the gap in between the K04 and the GTRS. It spools fast, really fast, so you get that instant torque/power and from the dyno I posted above it holds until atleast 6500 rpm, (on the wrong software!!) What is there not to love? I'm so stoked about this.

Originally I wanted to go GTRS, but after reading thread upon thread of lag, and lack of low end, I decided that it was not for me. Building a stroker engine is not in the works right now either. There is a website of a guy so dissapointed with his GTRS low end, that he added nitrous to help spool!!! http://crunchbucket.wordpress.com/20...-daily-driver/ The A4 is just too heavy to rely on a 1.8L engine until 3800rpm. Most of my driving is between 2-4,000rpm. I also want more power than a k04. This turbo fits the bill.

On K04 software the frankenturbo made 20whp and 20 wtq more than a K04 transverse setup. I'd be happy with that.

Here is a boost log of that dyno.

[EBG 18T]

it should be able to hold the 20# boost longer; well past 6k rpms.. atleast i know mine does.

This is not a new idea, there are several companies that modify a k03 to k04 spec, or upgrades to the k03 or k04. From my own research that I have done they tend to not have a long life, either bc of the software or bc its a modified turbo.

I am in the same boat as you, I want low end power not power starting at 3800rpms. And it is a good deal bc you get a ported manifold and tip. The software is my biggest concern tho. PLUS, i want bolt on power bc within 8 months from right now I will have my new toy - 1990 or 1994 zr1 13s stock and only getting faster , and the audi will be the DD.

Do they offer a discount if you send them your old turbo and/or manifold?
