Ttrs lpfp problems?

[Pikey Motorsports]

S3 injectors flow more and spray better than RS4 injectors.  Always have done.  Ditch the Revo map and go to Niki.  The big turbo maps were designed around ATP cast manifolds and GT series turbos.  Done about 5 years ago and things have moved on loads since then.  There is just no need for them to revisit them at the moment. I'm sure they will once they start doing their own bt kits.

Rs4 injectors were and are only used on US based maps as they were all that was available until the TTS was launched there.

I've just ordered some 155 bar return valves for the two Nortech kits I'm doing, and for my build. This should give enough fueling hopefully before needing anything else.  So many cool things that Niki will be working into these new maps. 

Is there any proof anywhere the s3 injectors flow more? There's so many mixed opinions on that?

Have you been told that recently about the BT maps? I have been told there new?

I have had going to niki in my mind before, but the car does drive great and makes good power and curve hmm it's a big decision

I believe the bt maps are still the same ones from when jonnyc had them.  May have had slight tweaks over the years.  Speak to Kev direct and ask him.

I have a K1 being mapped by Niki at the start of map using the Nortech kit.  Stock engine, but things like a hard cut rev limit will be added, gear based boost, pops and bangs like the rs focus and a mild launch control.  All using the stock n75 valve.  Using boost controllers is just a way of working around a map that isn't specific for a car.

I will try and find the vid showing the S3 injectors flowing more than the RS4 ones. There is also a TTS out there running 600bhp on S3 injectors.

I've seen the vid of; TFSI, S3, RS4 and some brand I couldn't make out on a bench flow tester aswel  S3 should be upto the job

They key is the fuel pressure, like you said Alex, with a 155FPRV and a good pump (LOBA or APR) you're able to run and hold massive pressures!

I may change in the future Alex.. But will probably stay where I am at the moment.. Us there any solution to sorting the lpfp from overheating?

The Uprated LPFP can overheat and APR say it is due to the difference in the wiring between the VW's and the TTRS/RS3. I haven't had any issues....so far and ran the R at Marham last year with the RS3 LPFP up to its top speed over and over again with no issues or codes.

The RS4 injectors are my only option with GIAC at the moment, but things change. 

Alex is right up to a point about using a boost controller, but you'll struggle to make the same top end power with a lower boosted turbo. N75 is limited for boost recognition and if you want to run 2+ bar of boost then you'll need a controller and then tune for it accordingly.

Not true on the boost pressure.  You could run 100000000 bar of boost, but the stock MAP sensor needs some trick calibration, or run a 4 bar sensor.

GIAC = American, so they say RS4 FTMFW Yo!

What's the usp controller just the ttrs one?

Yep.

What problems do these cause apart from it priming when you open the door?

Believe they can cause continuous running without the car running.  There is a good thread on Vortex somewhere.  GolfRS is the thread starter.

Around page 26 iirc.

Will check it out in a mo Alex.. I've seen apr say the controller fixes the overheating? What options do I have now then to fix this lpfp issue? I take it its necessary to keep upgraded lpfp with my setup atm to make the power

Interesting......i thought the general idea was that the s3 maxed out around 420-430...im sure id read that on here a few times,so what is the limiting factor to go more on say a stage 2+ car,the turbo?..

So does the ttrs lpfp actually do anything beneficial??
