FSE Fuel Pressure Regulator
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. We are continually developing new designs to expand the number of applications. We 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:
1:- lethargic throttle response
2:- occasional driveability problems at slow traffic speeds
3:- intermediate performance 'flat spots' when accelerating (Most noticeable on MAP sensor model cars and newer return less fuel rail systems)
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:-
1:- instant throttle response
2:- removal of performance flat spots
3:- faster acceleration
4:- extra engine performance
1:- The kit comes supplied with the adapter to fit into the fuel rail for most model vehicles and cover the whole Mitsubishi range.
2:- The kit comes supplied with the fuel pressure gauge for easy adjustment (Fitted inside engine bay only)
3:- This kit is compatible with both naturally aspirated (Recommended) and turbocharged cars (Highly recommended)
