fitting 850cc injectors
hi im fitting to MY00 uk classic turbo2000 a set of 850cc injectors and was hoping to find out if i still can drive hard if i wanted to with out remapping yet
as i got lots more still to go on my car like new turbo pistons rods crank bearings and dont want to map it and have to map it again after i put all the other stuff on
at the mo i have done 255 walb feul pump, sx blue performance feul regulater- with presure gauge and FMIC with custom pipping air filter at front bumper fog lite level

That's what I did with mine

why would you want to up the pressure on such huge injectors??
you up the fuel pressure to get more flow through smaller injectors....
a VF35 is only good for about 350.....850cc injectors however would have enough flow for about 600bhp...so theres a huge mismatch there, you only need 500s to max out a VF35.

850's are crazy. The spray pattern is not very good at all, and on a 2.0lt will be awfull on cruise.
With increased fuel pressure, you can squeeze circa 340bhp out 440's, 440bhp out of 550's, 600bhp out of 740's, and 690bhp out of 850's.
This assumes the parts, set up, and mapping are all very good.

360 bhp on my 550's at std pressure ( via walbro & reg etc, running TD05 and headers etc. ) and only seen 81% duty cycle max. So 20% more available from the 550 injector's without playing with fuel pressure increases for safety ..say good for 430 - 440 bhp as Mark says above.
