Hi Guys

My names Chris im new to the fourum, so bare with me, what to start a new topic see if any one could help or give me new ideas, I have a2004 (54 reg) Ford Focus 1.8 16v Zetec, ive been looing into ways to save money etc and aswell as better and ecnomical performance and I came accross the idea of putting an FSE boost valve as replacement for the standard feul pressure rgulator but I'm just wundering what peole think about them, and is there one available or somthing differnt for my year 2004 as iI believe that they stopped after 2000 ?!

Cheers for your time

Look forward to your responces

Chris

well for one boost valves wont save you fuel they will use more as they increase the fuel pressure meaning more fuel faster and from past experience you dont just stick it on as they say it has to be set to the car which means tuning which costs money they wont provide you with economical performance below is from haynes performance manual which shows how easy it isnt regulators pressure gauges rolling road and remaps all cost

An adjustable fuel pressure regulator . The

aftermarket units are a direct bolt- for the standard regulator. with the same vacuum connection,

but feature an adjuster screw on top. Loosening or tqhtening the adjuster will change the fuel

system pressure. Once you start playing with your fuel system, you must haw a reliable way to

measure the fuel pressure, which usually means installing a quality fuel pressure gauge. Most

enthusiasts mount theirs in the engine compartment, where they do most of their tuning work.

Some aftermarket gauges are designed to be screwed right into the fuel rail in pbce of the khrader

valve. An aftermarket fuel rail will usually have a threaded hole just for adding a gauge. It would

be nice to have the gauge inside the car to watch it under different driving conditions without

having to use a dyno, but a fuel gauge and fuel line inside the cockpit is patentially dangerous. A

problem with the gauge or the pressurised line supplying it could leave you with a faceful of fuel.

When you increase the fuel pressure in your fuel injection system, you're putting a greater load

on the injeaors themselves. Too much fuel pressure will shorten the life of the injectors. Experts tell

us that for road cars with mild M-on modifications, you shouldn't raise the factory fuel pressure

much more than 10%. On a whide with 45 psi as the standard pressure, you could safely raise it

with an adjustable regulator to 49.5 psi, assuming that your modifications require an increase.

If you assemble a high-pressure fuel system for a boosted or nitrous application, you must use a bypasstype

fuel-pressure regulator with a separate return line back to the fuel tank. Too much pressure without a

bypass regulator could cause the pump(s) lo fail. Also, use only high-pressure-rated metal or decent braided

hoses in a high-pressure system to avoid possible fuel line rupture.

Without your own roll ing road to examine your engine under all condtions, espeaally under load at fullthrottle,

you have to tune fuelling by feel and by ear. really they need to be set up by pros who can

help a lot because they know what's worked on engines like youres

fitting the regulator youre car will be "doggy" at the bottom end, and you'll be bogging down every time you pull away wrth less than -

6000 rpm showing. With a minor increase in fuel system pressure, you can have your standard ECU or chip

reprogrammed to handle higher fuel pressure, and this is recommended, but there is a limit to how much the . .

standard ECU can handle. An exhaust gas analyser is a big help, especially if you can run the car on a rolling .

road (driven by the car's wheels under load). You can also learn something from your friends

.
