--- Quote from: james on June 08, 2013, 09:00:53 am ---i am sure I was running around 135bar. I would be shocked if they was running 150bar as the rs4 valve could not cope with that.
I was just in the process of changing the LPFP before I left.

Maybe they have changed the RS4 valve to something larger or maybe it can handle 150bar I don't know but they are running 150bar.
Maybe its a valve from the 2.0TSI as that is able to run 150bar standard
james:
it is to do with how much they flow, I think they crack also.
Would be good to find out.
Janner_Sy:
Alex (vRSAlex) should be able to tell us i think.
Hurdy:
You can buy 145 and 155 bar fprv's too. The RS4 valve has a 136bar return pressure, but that doesn't mean you can't run higher fuel rail pressures, it just means that it is harder to maintain the pressure from the low pressure side. :smiley:

R-Tech seem to be the ones who are pushing the boundaries of the K04 at the moment. Havent seen them post in a bit though. Id like to know if it makes the gains on a K04 or if its only GTX28 and ihgher turbos which yield the benefits?
