555cc Inj Be Big Enough

[sinistaGTR]

Im just bout to get some new injectors,

Im aiming to have at least 330rwkw, im just deciding which size inj to go for. now i figure 555cc can handle 555 bhp which turns into roughly 414kw, once you take out say 50kw for driveline that equals 365rwkw. But the dilema is i dont want it to be near maxing the inj out, i would like to keep the inj duty under 80%, so would my best bet be 555cc or get 740cc just in case i make more power (i dont think i will but).

Will be fine for low 300's

Depends on ECU.What do you have?

If your worried you might make more, just get the bigger ones, the cost difference it stuff all

[sinistaGTR]

i have power fc, i also have a fpr if this helps

you can bin the fpr

^ Exactly!

Just get bigger injectors rather than trying to bump up the fuel pressure.

Sell your FPR and with the extra cash buy some bigger injectors

How?

[sinistaGTR]

yeh cool as lol just thought id check go for either 740 or 850cc then

AFAIK the difference between 555's and 740 NISMOs is about $5 from Nengun

If it helps, I made a touch over 300rwkw on 550cc injectors and stock fuel pressure, I don't remember exactly what the duty cycle on the injectors was but I think it was around 80-85%. It was deliberately tuned a little rich in the top end (we erred on the side of caution) but still had a bit of room to move.
