as above,which 1 are you using? i think mine is starting to fail so i will be replacing it

heres some i have seen so far

now i know the most expensive ones will be the best etc etc but are the cheaper ones any good? or are they not worth bothering with?

 

Fuelab gets my vote there without the doubts


Jura

 

cheers jura,will i need a map tweak after fitting?

also what other ones are available? isnt there sard ones? im guessing there is alot of fakes about

 

+1 Fuelabs. The Ebay one looks like a Fuelabs clone.

 

If you will keep OE fuel pressure or yours current one,you don't need map tweak,just would recommend at least check

Do you have AFR gauge(Wideband)?

Fuelab is best and we are used now for few years without the single issue,SARD one unsure there,never tried,but few guys from SN tried them(think JonMC running this or will be running this FPR) and yes lots of fakes are out too

Jura

 

fuel lab, avoid cheap ebay tat, if the car runs lean it will cause damage.

dont scrimp on important stuff

 

As Jura says, there are TONS of fake Sard ones out there.

 

no i dont have a gauge mate

 

looks like its gonna be a fuelab one then............merry xmas to me

 

Is the Torque Pro app accurate on reading the AFR?

 

Not really there,you will need wideband sensor(preferably with controller like is LC1,AEM UEGO etc),Torque using/reading still OE lambda sensor which is narrowband sensor


Jura

 

FuelLab, SX and the later design Sytec one you've pictured all work well.

Ideally you want to check your AFR's as any change in pressure will result in a change in fuel mixture.

The main issue with many of the cheaper regs is that they don't maintain a stable and consistent pressure.

Make sure you buy a 1:1 rate reg not a 1:1.7 rising rate model.

 

any ideas how many an fittings i will need,how many elbows/straights etc? and what size they need to be?

 

we always use/supply Fuelab THREE port versions as with most things we do they are "very" competitively priced (a full kit with the correct fittings is probably similiar to some of the bare links above)

we carry either -6 or 8mm tails and various hose options to suit budgets/builds

 

Can somebody explain which I would need or why I couldn't use a rising rate one? Car is a blob wrx running rcm 340 pump and 650cc injectors

 

a rising rate adds a multiplier of fuel (1.7 to 1) so instead of a linear rise as you have std it adds extra fuel to make the car richer for a given pressure

it was a very basic way of getting fuel into cars that cold not be mapped.......

 

Cheers alyn,does it matter which one I use?

 

you require a 1:1 linear rate.........

 

pm me a price matey

 

Anybody know what pressure these should run at or be set at?

 

depends what your trying to achieve but around 3BAR at idle (with no vacuum connection)
is a good starting point - this will drop to around 2.4 / 2.5BAR when all fully connected normally
