but get fpr defo

Si, what base pressure were you running?
 
cheers

for that price you might as well spend the extra 50 notes and get a real aeromotive fpr dont be cheap on it as the real one can handle greater pressures and be more reliable and hold consistant pressure, therefore less likly to fail

I have no idle issues relating to running 850ccx4 injectors, general fuel consumption appears to have not changed.

I think around 45 psi.  Carl would know, you could ask him..

hang on define a standard fuel system??

If its out of the box... about 260ish at the wheels with a PFC

With some tweaking to rail pressure etc as Blitzboy says its makes quite a difference, i have seen 300rwhp on 550\'s and 850\'s (but not far of its limit)

Yeah thats about right. Mine is 270 at the hubs on stock fuel system, but seeing over 90% injector duty.
