||FSE Power Boost Valve - Adjustable Fuel Pressure Regulator
Renault Clio Mk1 1.2i 04/96 on
The Power Boost Valve is a high performance tuning part which replaces the original equipment valve (fitted to the vehicle).
The benefits of the Power Boost Valve can be outlined by drawing comparisons with the original equipment fuel valve in your vehicle:
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 down to 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. However, the resultant effects of the standard valve means the throttle response is often lethargic, there are occasionally problems when driving at slow speeds and you may experience performance 'flat spots' when accelerating.
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 the fuel pressure is reduced by 0.5 bar approximately at idle but that is where 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, giving:
Instant throttle response.
Removal of performance flat spots.
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 maintenance free.
