5.0 bar fuel pressure regulator

[aronmatic2]

i have an audi s2 with rs2 engine, ported polished head, lancia valves, audi tt pistons, s4 intake monifold, nice home made exhaust manifold, 70mm exhaust system, large intercooler. i buoght 5.0 bar fuel pressure regulator. somebody says is not a good idea.
so. what you guys think? install or not?

5 bar pressure regulator wont be a problem. You'll need a decent fuel pump to keep up with it.

thanks. there i a lots of info. but if i order a 5 bar 3l/min fuel pump and i have 5 bar fuel pressure regulator, when the boost going up to 1.5 bar,the regulator pushing around 6.2 bar. it is still going to kill the fuel pump. or not?

5 bar fpr + 1.5bar boost = 6.5 bar fuel pressure - not 6.2 bar

[aronmatic2]

Dough

yes. your right.

what do you thik about the otherone?/12V / 14A bis 300l/h maximal 8 bar/

[aronmatic2]

Dough - h=Doug

sorry

[Doug_RS2]

Mark is running a 5bar fpr and he must be getting close to 2 bar boost - I run a 4 bar fpr and 2 bar boost with the 5 bar pump from Bosch - I doubt I am ever getting to it's limit of flow though even at higher pressures.

Did mark refit that 5 bar FPR then? Is this really needed?? I have only a 4 bar one along with the same pump and injectors.


Aronmatic2- what injectors are you using??
