In my opinion the best turbo to go for on the MQB platform if you don't want to go for stupid power then is the Turbo Technics V4, spool is near stock and power delivery is great. Followed by the Littco L380. 

Difference in price is at least 1000. And you need HPFP for sure, while for Powermax you do not need one. Power is lower for sure.
But it can be safe daily car with 420HP.

I was doing some logging and became curious as I see some other values on different forums for other cars (for example Golf 7R).

My requested pressure for LPFP is constant at 7 bars. Only when I was driving wot and released pedal it went to 5, but then back to 7 in second or two.

Actual value follows requested one, so this is not a problem. HPFP is also good, on wot to 200, actual following requested.

 

It just seems too much, 7 bar and everybody mention fuel filter in LPFP is declared on 6.5 bar. Duty Cycle is 64% on idle and it goes to 78% at wot, remaining 7 bar. 

On other forums people are mentioning 4, 5, 6 bar on idle, so I am not sure if this is normal.

 

Mine is 280 with MPI 2017, which probably makes a difference compared to other without MPI.

 

Is somebody able to log their LPFP requested/actual?

@KeithRBrown do you have final figures with PMax1?

 

I did turbo swap week ago, to Powermax Stage 1. There is still place for improvement of maps, which will be done in following period and with stock hpfp pressure is droping after 6000rpm, but power figures are promissing.

424hp and 560nm on 95

441hp and 593nm on 98

We do not have 100 octane fuel even it is advertised as 100, it is more 98. 

So 100oct map was not measured, but I can guess it is 450-460/600nm

 

I will probably go hpfp upgrade route. I am concerned about long term reliability. But it seems that problems come with E blend, which I do not intend to use, since we do not have it on gas stations. I guess there is lack of lubrication with E.

 

Car feels really fast and it is. I went from Stage 1 350hp/480nm to Stage 3, so it is significant increase.

I do not feel lag (it is comparable to Stage 1 responsivnes) and how it pulls in 4th is totaly different league.

I'm running a upgraded Hpfp for over 15000-20000 miles now, it been running from 480bhp then 540bhp and now 600bhp with no issue. Mines tuned on 98ron fuel (E5) 

Great to hear!

Autotech, VIS?

E5 is I guess weak mix to make big problems.

 

You have some times 100-200 for such power? 

Autotech, however my first one seized as it was design flaw. 

E10 - 95 Ron is the weak mix over here.

 

No times yet.

Salut Keith, oui ! Un panier de carburant RS3 LPFP s'installe directement et il suffit de se procurer le faisceau de câbles aux États-Unis. Aucun codage n'est nécessaire !

 

C'est la meilleure solution, mieux que d'essayer d'installer un nouveau lpfp dans le panier existant.

Hello, I need help installing a high-power low-pressure pump on my vehicle for a Stage 2 E85 flexfuel project. However, I'm having great difficulty finding a solution. I purchased a Bosch 0580200392 pump and a Bartek 590LH kit. assembles but as it is for type GOLF 7R the fuel gauge does not work it does not seem to be the same type because the tank is different, after several in-depth searches it seems that the VW ARTEON 280 / VW PASSAT B8 and SKODA SUPERB 3V 280 share the same platform with a specific pump and the same tank, my wiring concerning the fuel gauge is 3 pins, it seems that after several searches my car model is only compatible with a low pressure pump from Audi RS3 and that there is a plug & play wiring harness. https://scskunkwerks.com/en-gb/products/awd-mqb-rs3-pump-hardware-and-harness-kit?variant=47121984880961

If you know how to install it, please let me know which pump/harness I should purchase to install a high-power, low-pressure pump.
Thank you for your help.
Kind regards,

Hi

The Superb/Passat/Arteon 280 share the same LPFP as the RS3 so it simple to plug it and it works. I bought the same kit from SC Skunkwerks, recieved a great service.

What power are you aiming for? The stock LPFP is good enough for over 500bhp unfortunately we never tested it to the limit however the tuner said there was capacity to push it further.

Edited 28 October, 202528 Oct by Awesam

Thank you very much for your help Awesam so I have to buy an original RS3 8V bp pump, reference 8V0919087A but for the wiring how to proceed because mine is original on the Skoda the power supply of the pump is 2 pins (RS3 4 pins) and the fuel gauge is 3 pins (RS3 6 pins)

We can see in picture the différences of connectors, and for the fuel level its working ? No error on fuel level sensor résistance ohm ? Thxxxxx

Salut

Les Superb/Passat/Arteon 280 partagent le même LPFP que la RS3, il est donc simple de le brancher et il fonctionne. J'ai acheté le même kit chez SC Skunkwerks et j'ai bénéficié d'un excellent service.

Quelle puissance visez-vous ? Le LPFP d'origine est suffisant pour plus de 500 ch. Malheureusement, nous ne l'avons jamais poussé à sa limite, mais le préparateur a indiqué qu'il était possible de le pousser plus loin.

I have HPFP autotech / MPI injecteurs 980cc Bosch / VWR R600 intake / NGK iridium spark plugs / VWR ignition coils / next modification will be Wagner intercooler and downpipe supersprint

Here in France we have the superethanol my objective is to have the maximum power in 100% E85 in accordance with the maximum capacity of torque of my DQ250

So TCU Tune + stage 2 E85

But this problem with LPFP is occuping my brain for weeks 🥹🥹

You need to buy this harness: AWD MQB RS3 Pump Hardware and Harness Kit – SC SkunkWerks

to make it work and there were no errors, the Engine Builder put it all in and started the car no issues/errors at all, you will need use the RS3 LPFP fuel controller.

As you have the LPFP, I may have the a wiring diagram so you could make the wiring loom yourself.

I had the issue with the LPFP initially aswell then I become the guinea pig to test if a RS3 LPFP would fit in a Superb, fortunately for me it worked!

Bosch 980cc MPI's are really needed if you arent going to exceed 550bhp however ever little bit helps. Supersprint is crazy expensive!

Vous devez acheter ce faisceau : Kit de matériel et de faisceau de pompe AWD MQB RS3 – SC SkunkWerks

pour le faire fonctionner et il n'y a eu aucune erreur, le constructeur du moteur a tout mis en place et a démarré la voiture sans aucun problème/erreur, vous devrez utiliser le contrôleur de carburant RS3 LPFP.

Comme vous avez le LPFP, j'ai peut-être un schéma de câblage pour que vous puissiez fabriquer vous-même le faisceau de câbles.

J'ai eu le problème avec le LPFP au début aussi, puis je suis devenu le cobaye pour tester si un LPFP RS3 s'adapterait dans une Superb, heureusement pour moi, cela a fonctionné !

Les moteurs Bosch MPI de 980 cm³ sont indispensables si vous ne voulez pas dépasser 550 ch, mais chaque petit détail compte. Supersprint est hors de prix !

Thanks a lot but it seems the article is sold out on the site but i think this one is the same : https://www.hpamotorsports.com/products/hpa-mqb-ea888-gen-3-brushless-in-tank-fuel-pump?srsltid=AfmBOopZ7KVWZUH9te3yJipYgYt7AygOU_jKW3DPwf2DSwm3zhOPYIZJ what do you think about ? I need to find a site where it can ship to Europe France, can you send me the picture of the wiring more clear i can not see the figure. Thanks

Thank you very much my friend, however before placing the order you have to choose an option but I don't really understand what that corresponds to.

Awesam did your fuel gauge work correctly right after the swap (no inverted readings)?

You posted a wiring diagram, but unfortunately the image quality on the forum is quite low and I can’t clearly see the pin numbers or wire colors.

Would you mind please sending me the diagram or a higher-resolution picture directly? That would be incredibly helpful.

Thank you so much for sharing all this information on the forum — it’s really helping people like me who are running the same car and facing the same challenge.

It seems you’ve found the perfect solution by fitting the RS3 8V LPFP with the wiring harness for EA888.3, and I’d really like to follow your setup.

Best regards and greetings from France

I just realized when I validated the basket that it's to change the fuel line between the LPFP and the HPFP, but I don't think I'll change it, it must be a real pain to run all that and I think the OEM hose is strong enough, what do you think?

@Awesam I don't plan to change the fuel line because I've done my research, and for my Stage 2 E85 project (HP Autotech / Wagner intercooler / RS3 LPFP / Bosch 980cc MPI / downpipe), with a potential power output of around 400 horsepower, it's not necessary.

1. The original fuel lines:

On the Superb (like the Golf 7R / S3 8V), the fuel line is already made of high-pressure polyamide (PA12), which is resistant to ethanol.

It can withstand up to approximately 8 bar, which is significantly more than the 4–5 bar that the low-pressure pump will deliver.

It will never burst due to the flow rate, as the pressure remains regulated by the LPFP module.

👉 So yes, mechanically and chemically, the OEM fuel line will hold up without any problems, even with a 540–590 L/h pump and E85.

2. Why some people install the reinforced kit:

The goal isn't pressure resistance, but reducing internal restriction.

The original hose has an internal diameter of approximately 6 mm, while the PR Fuel Line kit uses AN-6 (approximately 8 mm internal diameter).

This larger diameter reduces pressure drop at high flow rates (useful for engines over 500 whp or Stage 3 E85 with MPI injectors).

The kit is also 100% metal/braided, so it doesn't expand and maintains its shape over time.

@Awesam

Hi mate,

I hope you’re doing well and thanks again for all the details you shared about your RS3 brushless LPFP swap on your Superb — your post has been super helpful!

I’m currently installing the same setup on my Skoda Superb 2.0 TSI 280 (EA888.3) using the EQT brushless RS3 pump and harness, but I’ve run into two issues I’d like your advice on:

1️⃣ Main 5-pin connector fitment

On my car, the OEM 5-pin connector doesn’t seem to lock mechanically into the black 5-pin connector from the EQT/RS3 harness — it looks like the keying tabs or guides are slightly different.

Did you encounter the same issue when you plugged in the harness?

Did you have to trim or modify the connector housing in any way, or is there a specific orientation to make it fit?

2️⃣ Fuel level sender calibration

The fuel level sensor is working, but it reads too low.

When the float is fully up (tank full), the gauge only shows about +¼ of a tank on the cluster. (Orange line on the picture)

it seems like the RS3 sender uses a different resistance curve.

Did you face the same problem, and if so, how did you fix it?

Was it solved automatically once everything was wired with the controller, or did you need a coding/calibration change?

If you still have a clearer copy of your wiring diagram, could you please send it to me directly?

It would really help me confirm all pin positions before final assembly.

Thanks a lot for your help mate — your build thread has saved me a ton of trial and error already 🙏

Best regards from France

Hi my engine builder said he just plug it in and it all worked. I will ask him and see if he can shed any light on your issues.

@Awesam

Hey mate,

I think I’ve just figured out part of the issue with my fuel gauge reading too low during testing.

On the Skoda Superb 3V, the fuel tank has a “saddle” shape (split into left and right sections).

The right side (passenger side) houses the main pump module with the primary level sender (the one integrated into the RS3/EQT brushless assembly).

The left side (driver side) has a secondary sender unit — it doesn’t pump fuel, but it contains another float and a siphon/jet system that transfers fuel to the main side.

Both level sensors are electrically linked and their readings are combined by the instrument cluster to display the total fuel level.

So when I was testing the new EQT RS3 pump by itself, with only the main right-side sender connected, the gauge only went up to about ¼–⅓ full, even with the float fully raised.

That actually makes sense now — the cluster was missing the signal from the left sender.

Once both senders (left + right) are plugged in, the gauge should display the full combined value correctly.

So I’ll finish the full installation and retest everything with both sides connected before suspecting any calibration or resist

ance mismatch.

@Awesam

Finally, I managed to connect the pump; it is indeed plug and play. The connector on the pump side had the pink tab inside slightly misaligned; I put it back in place. Now everything is in order, the pump works well. I have an appointment with the tuner Fredautosport in a few days for the configuration. So, I have a VWR R600 intake, large volume inlet & outlet turbo, GFB DV+ dump valve, Autotech kit on HPFP, EQT RS3 type brushless LPFP. The next modifications are a Wagner Tuning downpipe and intercooler. I found a downpipe reference; what do you think, Awesam?

Cheaper than supersprint 800+ euros

Thanks for your help
