FSE – ‘Power Boost Valves'

What is a Power boost valve?

The Power Boost Valve is an Adjustable Fuel Pressure Regulator.

The Power Boost Valve is designed for use on ‘Electric Fuel Injection' engines with a special fuel enrichment facility for acceleration, commonly known as a ‘Rising Fuel Rate'. The enrichment is 1.7 : 1.

How does the power boost valve work?

As standard the original equipment 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

However, the FSE Power Boost 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. 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 benefits of the Power Boost Valve are: -

• Suitable for Standard and Tuned Vehicles
• Quicker Throttle Response
• Faster Acceleration
• Throttle Hesitation (in most cases eliminated)
• Normal Idle (with adjustment) retained
• Normal economy on light throttle
• General fitting instructions included
