She's running 550 injectors, APS turbo, APS intercooler, Tek3 and dawes, etc,etc...thinking of upping boost more using daul stage dawes and water injection...thing is, the std reg is crap when used with uprated pump.
Reg must be changed, but just need to know if the FSE 1.7 times faster pickup would be any good?

It will need remapping with either anyway... and can therefore be mapped to suit which ever you decide to go for.
Although I suppose you could run standard pressure with the 1:1 and the map should be fine although slightly rich perhaps if the old pump and reg was under fueling..
David knows far more on the subject..

I know it needs remap really, but don't want to do it yet...hence, I'll fit uprated reg, maybe FSE 1.7 at almost std reg pressure for now...at least that pressure will be consistent. Don't want another remap until the clutch, gearbox, rear diff and water injection added - my project for this year..

I'd wait until water injection and do fuel pump, regulator at the same time as the water injection then get it mapped asap..
gearbox and clutch are not going to effect the map.. others will..
imho

Ah, na m8...fuel pump already done and part of Tek3 map. Need clutch/gearbox etc done as car can't take current torque. Think uprated reg set with almost std pressure will not change the current fuel flow to be outside the narrowband of ECU.

Harvey, I'm looking to set FSE pressure (I'm 80% sure that's what I'll buy) at tickover at around 2.6/2.7 bar with engine warm. I'll then check the AF ratio and maybe up it to about 3 bar max (at tickover) and see what tickover is like, and what ratio is like with dawes & tek3.

If you are going to use an FSE regulator and up the base presure to 3BAR on idle with the vacumn pipe attached then you are going to be limited to 1.5BAR boost, you will need something like the SX regulator for any more.
I would use a 1:1 regulator for the reasons harvey mentions, using a rising rate reg will be dificult to map and if you use it without a remap its going to run rich at the top end losing you power.
Running the base presure higher improves the atomisation of the injectors and will allow you to have more headroom available for future mods.

RCMS or something sell the SX regs? USA though yeh. I've read they run over the 5 psi mark which is limit for FSE (as above) - thanks for this guys...looks like that's my best option...know where I can get one and if they come with a fitting kit for My02?

And some additional comment the rising rate is not a consistent performer, also its not very rising rate either, it isn't easy to map for that reason, its bad enough mapping with elevated fuel pressure as the fuel map gets very flat due to the increased pressure without the damn pressure hopping around at a given boost level.

Also you want to set it to 3bar with the vaccum line disconnected and blocked off.. 3bar will then be the same as standard.. 3bar with the vacuum line attached is about 3.7bar..
Mark can also supply a FSE www.lateralperformance.co.uk

Cheers Guys...
Not sure if I'll get the SX reg yet...it's well expensive!
Don;t like the FSE at all now with all your comments.
Just to make it clear (as I'm not sure my replies confirm this). I've had turbo, injectors, pump and tek3 remap done but with original reg. If I fit 1:1 uprated reg at almost std reg pressure (with blocked hose), will the car run okay for now or will the uprated reg allow much higher fuel flow at higher revs?

if you had the remap whilst the standard fuel pump was in use then you should be OK with the FSE set to 3BAR atmospheric (vacumn pipe disconected at idle). If you had the remap with the uprated fuel pump then you will get a diferent fuel presure through the rev range than how it was mapped, so you really would need a remap to be sure of being safe.
The reality is, whatever you do you should get a wide band lambda on the car and check the fuelling is safe as an absolute minimum and you will require a remap to have it running properly.

Thanks for that...looks like remap it is. My only trouble is the car needs work on transmittion before I can put it through another load of tuning - won't be till mid/end of year - argh.

Cheers Jolly Green but that's for the classic and I know from Dr Banks that the FPR locations are different for new age. Anyone got pics of new age fitting? At least I now know what to look for re the OE FPR...think I've seen that somewhere.

JGM...don't really know mate...just going by post from Dr Banks...he said classic was difficult to change FPR, but new age easy as it's at the 'front of the fuel rail'...I'll have a good look for the OE item as I'm sure it will look the same.
