Am i right in thinking these are only neccessary when upping the boost? The standard ones can cope just about with standard boost levels (3 bar at idle and rising with boost).
If not what are the reasons?

 

3 bar at idle

boost should be (on the guage anyway) well below zero at idle and max should be in and around 0.8 - 0.9 bar.

3bar FUEL pressure at idle

Walboro Fuel Pumps Rock, but the standard fuel reg may not be able to cope with it...

 

sorry, wasnt very clear. I meant are they only neccessary when upping turbo boost as the fuel pressure in the rails has to increase from 3 bar at idle plus whatever the turbo boost is. So if your ruuning 1.4 bar of turbo boost the fuel pressure raises from 3 to 4.4 bar (which the standard pumps might struggle)

 

2.8-3.0bar fuel pressure is about right at idle.maybe a little less

 

3 bar at idle . had a jet engine implant.

 

I'm running less than 3 bar at idle. What should i be running?

 

In fact i'm running 2 bar at idle!! just checked
