Technical uno turbo fuel pressure with gt injectors

[philly g]

Hi chaps, what fuel pressure is good to run gt injectors on a mk2? currently its on 3.5bar. car made 206 bhp atf, 172 atw. that was on standard injectors 16psi boost. wanna take the boost to around 19-20 psi. just dont want it running too rich.

Cheers

You cant just pick a number. you need a reason.

What have you done to the engine, 200hp is optimistic to say the least.

what you mean cant just pick a number? check out dyno print out. no sh*t steve. cars running out of fuel, with standard injectors, i got a set of injectors, just wanna know what sort of pressure best to run, or go back to the standard fpr.

standard compression ratio
1.9mm spesso head gasket
1.3 uno turbo ported/polished head
matched manifolds
piper 285 cam
t25 turbo, (rover 220)
cossie 4x4 intercooler
2.5" hard pipe kit
230cc injectors (punto gt) (too fit!)
fse fuel regulator
uprated oil pump
oil catch tank
lightened flywheel+balanced crank
organic clutch
modded throttle butterfly.

sounds nice and how did you mod the punto gt injectors into the mk1 rail as they dont fit, also you fitted a t25 on a mk1 engine so did you use a mk2 exhaust manifold i would let the rr bloke fiddle with the fuel settings, you are on the limit with the standard hardware and need to upgrade to megasquirt or mr dictator mappable for the system and injectors Ant! any pics??

hi ant, its not a mk1, its a 93 mk2, just using a mk1 head, as my mk2 head was cracked and mk1 heads are better. i havent fitted the injectors yet, will be soon, i aint gona push the engine much more to need different management, 19-20 psi should see it to 230bhp , and that will be it. i'll get some pictures up soon.

Leave it standard unless you have a reason to change it.
