do you need to put an adjustable in there? or is all the standard stuff fine?

Depends if the chips mapped for a rising rate FPR or not, i know Lee's Turbo clio has a FPR with vac connection on it, so it's rising rate.
Alsmot certtain coops is the same and no doubt maxiboy.
If your using a FastChip you'd need one i reckon.
pm replied and as above, rising rate required
i have a weber adjustable fpr setup for the turbo conversion
if you are after one
yes, as fuel pressure needs to increase proportionally to intake boost pressure.
that's what connecting the vac line doesOriginally Posted by stan
Unless you can map it to a static pressure of 3 bar? or do the injectors run out of puff at 3 bar on a turbo setup?
the reason you run a pressure/vac feed to the regulator is to sustain a constant pressure. Boost inside the inlet will create a restriction to fuel trying to exit the injectors, so you add boost pressure to fuel pressure and get a constant. If you run without a vac line attached, your fuel pressure is effectively being reduced by boost, so run 1 bar of boost, and you get 2 bar fuel pressure (in effect).Originally Posted by Laine_16v
doesnt the standard fuel rail and reg work, it has a vaccume line...
I believe the standard regulator works the opposite way around. I.e it decreases fuel pressure with VAC, to save fuel while cruising.Originally Posted by AndyFielder
