      The flow tests are not done at full pressure, they are done at only about 100psi if i recall correctly from speaking with the company who makes the machine.

      exactly.
      So the flow/spray pattern @ 135bar (1958.00946psi) is completely different that those documents showing 100psi flow/spray pattern.
      The stock valve on it's best day only provides 1885.49059 psi of pressure which most don't even get to see.
      With the RS4 valve the minimum psi seen is the maximum of the stock GTi one.

      From the looks of it, this is really only beneficial for BT cars, or at least vehicles equipped with anything but a K03. Is that right? Would this be a beneficial mod for someone running stage 2+ on stock K03? Excuse my noobness lol.

      no. It's beneficial for anyone running a HPFP with the software requesting 127+ bar of fuel rail pressure.
      I believe uni is the only tuner requesting under 127bar.

      might not be the case.... towards the end of my cars stage2 life.. it appeared that my car was lacking a little bit of power... we never really looked into it so maybe I was hitting the valves max capacity even with stage 2. who knows... only way to find out is to test it yourself. Run logs ripping through 2nd 3rd, 4th, and 5th and see how low your values go for actual fuel pressure.

      My new valve should arrive early next week. Any requests for before and after comparison logs? Tell me which blocks you want to see and under which kind of driving conditions.

      Hmmm, i'd like you to log intake temps and oil level while doing a 180 turn going backwards...
      Yeah...that should do it !!!!

      then go to support and log what they consider round 1 and round 4.

      I bet uni will custom tune to 135 bar shortly.

      Why stop there?
      If im not mistaking the 1.4TSI twin charged thats used in Europe runs up to 150 bar .
      So just as long as the pump can put it out and the fuel system can support it im sure the tuners can get more fueling out of those rs4 injectors and then will need the limiting valve from the 1.4TSI Bob.G

      IIRC the 2.0TSI also uses a 150bar limiting valve.

      Is it a plug and play swap in the FSI fuel rail?
      That would be nice !!!!! Bob.G

      150bar? May not be a good idea. Doesn't anyone remember this from back in the day?

      Prob failed because the mechanical limits of the flat tappet follower setup in the FSI
      It would have to follow basically how the HPFP system on the TSI engine with some type of roller follower IMO. Bob.G

      Staulkor, did you use the part number mentioned earlier (079130757) on genuinevwaudiparts.com and under what Audi model did you search because I found only A6, Q5, R8 and S6. And somebody mentioned revision A - are there a couple of revisions and which one is the right one? Thanks.

      I went to the Audi stealership prior to purchasing te correct valve online. The one you speak of is the A version meant for the models you speak of. The 079130757 is RS4 specific.

      So how do we order one from genuinevwaudiparts.com if there's no RS4 option when searching and you can't search for 079130757?
      Thanks

      If i am not mistaken the limiting valve on a TSI does not screw into the fuel rail it is built internal to the hpfp.

      You're right . . . I just checked and the pump can produce a maximum of 150bar but the pressure limiting valve which is internal to the pump opens at 200 bar. Lol.

      What is the current best price for the RS4 valve? If i can get a few people together i can do $74 plus shipping...not sure how that comes in the market though.

      I got mine for 100 shipped

      I knew I houldve let you get it for me through your Audi connect.
      Unfortunately, I was in a rush.
      I'm going to PM you for some other parts.

      genuinevwaudiparts.com has the valve for $70.20 + shipping.

      it would be in the market somewhere between genuinevwaudiparts and worldimpex.

      Thanks CoNGLo, I did find it on ecs site and worldimpex but I was more interested in Staulkor's post where he was able to get it for $70 from genuinevwaudiparts.com - I couldn't find it there. Anyways, if TSI cars don't need one, great, I'll stop looking!
