Range Rover 3.9 Litre EFi
HOW DOES THE POWER BOOST VALVE WORK?
The Power Boost Valve is a high performance tuning part which replaces the original equipment valve (fitted to the vehicle).
A range of models are available to suit a wide variety of European cars, which almost certainly includes yours. FSE are continually developing new designs to expand the number of applications.
FSE outline the benefits of the Power Boost Valve by drawing a comparison evaluation:
Ref: Original Equipment Fuel Pressure Control Valve
The electric fuel pump supplies fuel at a high pressure to the fuel rail and injectors, which is then regulated by a fuel pressure control valve. Typically, the regulator is not adjustable and is pre-set to a 3 bar maximum pressure. At idle the fuel pressure valve reduces it by 0.5 bar approximately to 2.5 bar. When accelerating quickly from standstill the fuel pressure increases at a proportional rate retaining a lean fuel mixture strength as required by the E.E.C. for new vehicles. However, the resultant effects of the standard valve produce:
lethargic throttle response
occasional drivability problems at slow traffic speeds
intermediate performance 'flat spots' when accelerating
By comparison:
Ref: Power Boost Valve (replacement)
Firstly, this valve has an adjustable fuel pressure, effected by the movement of an adjustment screw on the crown of the unit.
New Power Boost Valves are pre-set with a maximum fuel pressure of 2.5, 3.0 or 3.5 bar, depending on the vehicle in question, and similarly (to the original valve) the fuel pressure is reduced by 0.5 bar approximately at idle. There the similarities end.
On acceleration from standstill the Power Boost Valve fuel pressure will increase at 1.7 times the standard rate. This will produce a healthy, strong fuel mixture strength which will instantly improve the drivability of your vehicle, providing:-
instant throttle response
removal of performance flat spots
faster acceleration
extra engine performance
The regulator enhances engine performance on acceleration by enriching the mixture strength. On constant throttle and cruise conditions the valve returns to a normal regulator function.
The Power Boost Valve is simple to install and in most instances basic fitting instructions are provided. These units are mechanical and are considered to be maintenance free.
