Why would you run at 5 bar? You need a pump that's going to pump at 5 bar + boost pressure and that means a motorsport 10 bar pump

I would think he wants more fuel from the injectors

Yes but I'm pointing out unless you got a motorsport pump you can't do it as the pump wont flow at the elevated fuel pressure on boost. A stock 044 can't flow at those level.

Buy bigger injectors!

hey i am only asking about the max pressure that can be used in the RS2 injectors.

of course i dont want 5bar FPR....but i would like to know the question about i am asking.

it is only because now with my current injectors ,7A FPR and RS2 fuel pump relayed to 14volts it is enough for my setup. but because i have AFR numbers in WOT like 12 - 12´3 it would be fun test with a adjustable fuel pressure regulator with a little more pressure in the fuel rail if the AFR numbers could go richer in WOT like 11´8 -12 only this...

i had used the 440cc/3bar apple green injectors and the AFR numbers in WOT were 10´2 ... too rich

thanks for answer Jonas and Jamo

I guess you could buy an adjustable FPR and try to set the fuel pressure up like 0.2 bar.

thanks Jonas,and then...any suggestion?? 034 Motorsport sells somes...but surelly any aftermarket could helps if it can be used for more than 4 bar

You can mod your factory fpr.
Just put it in a jaw and press it with a 1/2" bit a little.
So you tension the spring a little more inside...
It is a one way mod

But it is cheap and is ok up to 0,5bar extra.

Does anyone know anything about this injector:
