RS4 fuel pressure rail
« on: September 16, 2010, 05:25:12 pm »
Hi,
I went to the night at Brands Hatch a few months ago and I think it was Jabbalad I may of been talking to about an RS4 fuel pressure rail?
Was it that?  Something about fuel pressure and the stock unit doesn't provide enough?  An RS4 unit is a direct replacement....
Can anyone confirm this?  If so, who's done it and what benefits are there?
Have you had any issues and does it work well with a stage 2+ remap?
Is it easy to fit?  :popcornsoda:

Thanks

it is the RS4 pressure return valve.

It operates up at 136 bar instead of 130 bar like the S3/ED30 one. PITA to fit, but can help the fuel pressure meet requested easier on a stage 2+ car. :smiley:

There you go mate



I have also installed this valve on my car as well (just so you know it will not fix flat spots but it does make stage2+ smoother on pick up from driving experience).
