Gasoline Pressure Regulator WRX/STI Gold Series
Unlike the adjustable controller this model also offers the advantage of having a 1/1.4 ratio.
To make you understand better I bring a small example:
CLASSIUM SIMMETRIC PETROL PRESSURE REGULATOR.
PRESS. BENZ. INITIAL CALIBRATION – 3 BAR +
TURBINE BOOST PRESSURE- 1 BAR =
FINAL RESULT OF GASOLINE PRESSURE 4 BAR
Now in this condition, if we needed to give + gasoline to our engine because it runs lean, we would have to act on the pressure setting and increase it by just enough to bring us into carburetion at the medium and high revs. But if the carburetion turned out to be very lean, we would have to increase the pressure setting by a lot as well, thus going to DARK the carburetion at low revs (with the obvious consequences of loss of torque, pollution, consumption and immediate deterioration of the catalytic converter). So we should compromise by making do with what we can do. Conclusion: dirty delivery in the low range, almost good in the midrange, and in the high range bordering on lean.
With the ASYMMETRIC 1/1.4 regulator this problem disappears, as the percentage increase is asymmetrical to the turbine pressure, example:
PRESS. BENZ. INITIAL CALIBRATION – 3 BAR +
TURBINE SUPPRESSURE 1 BAR =
(contribution of 1.4 bar of gasoline pressure)
FINAL RESULT OF BENZINE PRESSURE 4.4 BAR
In addition to being asymmetric it is also progressive, so the pressure increase is proportional even from low turbine pressures, every tenth of a bar turbine will result in an increase of 1.4 tenths gasoline pressure. It is also adjustable, and also still interchangeable with the original regulator, so no modification to make for mounting.
No inappropriate and dangerous gasoline pressure-laden hoses to carry around the engine compartment.
