|COMPETITION FUEL PRESSURE REGULATOR Ref: VK-384-WRX-H|
RRP £145.80 +VAT
FSE Power Boost Valve fuel pressure regulator that replaces the original equipment valve.
How does it work?
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
On acceleration 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
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.
