Rising rate adjustable Fuel pressure regulator - Aluminium

Allows you to increase the fuel pressure when there is turbo pressure. ratio of 1:1 to 14:1

Perfect for your normally aspired engine converted in turbo and still keeping the standard ECU.

Full aluminum aviation regulator with stainless steel main adjustment screws, brass secondary adjustment screws and brass pressure/ vacuum socket.

Supplied with fittings for hoses Ø8mm, Ø12mm and AN6.

Example with our model 6:1, If you have 0.5 bar pressure turbo you will get 6 x 0.5 bar fuel pressure in addition of the original pressure .

That is to say 3 bar plus 3 original bars = 6 bar in the fuel rail.

The central bolt is for the base pressure when idling.
The latteral bolt is to adjust the rising of fuel pressure when on boost. It means if your Wideband Air Fuel Ratio gauge (see our PROSPORT GAUGES) tells you that you are missing fuel in high revs and loads, then you will screw a bit the latteral bolt. It will raise a bit the pressure in the rail while ON boost and give the engine the fuel it needs.

It should not exceed 3 or 4 bars in addition to the original pressure.

Your injectors will send more fuel to suit the additionnal amount of air sent by the turbo.
