HOW THE POWER BOOST VALVE WORKS

The FSE Power Boost Valve is a high performance fuel system part which replaces the original fuel
pressure regulator valve which is fitted to the vehicle at the factory.  There are a massive range of
Power Boost Valves to suit a huge variety of European and Japanese cars, with one almost
certainly available for your car.  FSE are constantly adding a new parts to increase the number of
cars to which the Power Boost Valve can be fitted.

Th benefits of the Power Boost Valve over the standard part is as follows.

The cars original fuel pressure regulator is supplied with petrol by the cars electric fuel pump. The
standard fuel pressure regulator increases the fuel pressure when accelerating but also maintains
a lean air:fuel mixture when accelerating so as to comply with EC emission regulations.

The FSE Power Boost valve increases the fuel pressure at 1.7 times the rate of the standard valve
resulting in a rich fuel mixture which increases throttle response, eliminates power flat spots,
gives more engine power and increased acceleration.

At idle and constant throttle situations the Power Boost Valve operates in the same way as the
standard fuel pressure regulator by reducing fuel pressure by approx 0.5 bar to maintain fuel
economy.

FSE Power Boost Valves are supplied with the correct fuel pressure settings for the specific car
they are intended for, meaning that no setting up work is required when fitting the part. Just
attach the part and you are ready to go.

The Power Boost Valve is straightforward to install and comes with basic fitting instructions.  FSE
Power Boost Valves are operated mechanically and are considered maintenance free.

In Summary the Benefits of the Power Boost Valve over the standard fuel pressure regulator are
as follows.
