Hi everyone i have just fitted cosworth management to an rs turbo but whilst trying to get it started one of my mates came to give a hand and was messing with the fuel pressure regulator just winding it in and out now not sure if it is ok. The car runs and drives ok but want to check it to be on the safe side so does any one know what it should be at roughly thanks.

 

not sure on a rs turbo,but on cossie general rule is 3 bar with vacuum pipe on,or 3.5 bar with pipe off

 

You need to set the static fuel pressure to whatever the chip is calibrated for.. 3-3.5 bar is a good starting point.

 

Just take it to a rolling road, unless you want to risk meltdown!!

Thanks all going to take it to carwise when run in to get it set up properly just trying to get it close to spec while running in.
