Suitable for all Fiat Alfa Romeo Abarth 1.4 T-Jet engines. Unlike the standard regulator, this model also offers the advantage of a 1 / 1.4 ratio. To help you understand better, here is a small example. Classic symmetrical fuel pressure regulator.

Initial calibration - 3 bar + turbine boost pressure - 1 bar = final fuel pressure of 4 bar. Now under this condition, if we need to add more fuel to our engine because it is running lean, we must adjust the pressure regulator and increase it sufficiently to bring us to the average and high-pressure fueling. With the obvious consequences of loss of torque, pollution, consumption, and immediate deterioration of the catalyst. Therefore, we must find a compromise to satisfy what we can do.

Conclusion: Dirty delivery at the bottom, almost good in the middle, and at the limit of lean at the top. With the asymmetric regulator 1 / 1.4, this problem disappears, as the percentage increase is asymmetric to the turbine pressure.

For example: Initial calibration - 3 bar + turbine boost pressure of 1 bar = (1.4 bar fuel pressure supply) Final fuel pressure of 4.4 bar. In addition to being asymmetric, it is also progressive, so the increase in pressure is also proportional to the low turbine pressure; each tenth of the turbine at bar will result in an increase of 1.4 tenths of fuel pressure. It is also registered and is always interchangeable with the original regulator, so no modifications are needed for assembly.

Max flow: 3 bar = 270 l/h - 4 bar = 220 l/h - 5 bar = 190 l/h. In our concept store, we are constantly searching for everything that is in fashion. The types of products we handle are the most varied! Therefore, we must find a compromise to satisfy what we can do.
