Power Boost Valves
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:
-
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:-
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.
We thank you for your interest in our products and hope that this
bulletin provides you with enough information to answer any questions
when making a purchase.
COMPETITION USE ENQUIRIES
The same range of regulators will be utilised when used on a competition
engine and, for customers using competition fuel lines, a special
regulator with a JIC (-6) male fitting has been prepared should one be
required. Fuel pressure adjustment can be effected in
seconds to reduce delays.
Gauge shown above is not included in kits
Gauge is for setting up & should not be left fitted in
place.
Available as an option @ £19.95 incl vat
This is for a pressure
gauge only to set up FSE valve
