Phase Kit Fuel Pressure

[Allen Mead]

Would someone kindly list out the fuel pressures for all phase kits (including phase 5) for Idle with no vaccum, Idle with vaccum and at full boost.

Cheers.

allways on idle without vacuum:
P1+2 3.5Bar
P3+3.5 4.5Bar
P4 6.0Bar
P5 4-4.5Bar


For fuelpressure at full boost, you have to add the boost! Thats all...
The fuelpressureregulatur keeps the difference between fuelpressure and inletmanifold allways at the specified level.

So P4 at 2Bar boost means 8Bar fuelpressure,
P4 at idle at about -0.7Bar means 5.3Bar fuelpressure. Very easy!

Gruß, Stephan

In that case, does this mean that the engine would be running rich on full boost and not at stoich?
