Nismo 740cc Injectors -- Too Small ?

[Guilt-Toy]

I am after the magical 500rwhp and I have been told by a few people that the Nismo 740cc injectors wont cut the mustard and that will need to upgrade to a 1000cc injector.

I cant really believe that this is true.. does anyone know what power nismo 740cc injectors would be good for ? its on my RB30DET.

I dont really want to run more then 92% injector duty

[Pauly33GTS-t]

whats 92 percent of 740hp?

[Guilt-Toy]

Enough for my target

whats 92 percent of 740hp?

[Pauly33GTS-t]

or is it 15 to 17cc = 1 hp ... i forget.

EDIT: I think that's at engine... and a typical calculation for normal modern cars...

Im sure that Nismo 555cc injectors are rated 555hp, and 740cc injectors are 740hp...

they will be fine for 500whp.

[2rismo]

They'll be more than enough.

1000cc injectors for 500rwhp? Ignore whoever told you that.

You plan on attempting to push 500rwhp with the 3540?

[R31Nismoid]

No reason it cant do it IMO.

Yeah, i suck

[MANWHORE]

Nismoid, do you have 360 rwkw in your r31? far out, she must chirp seconds. how's the response? like when do you get full boost by? rb30, 25 or 26?

Anyways, so answer your question, sydneykid usually says the cc rating is approximately equivalent to the hp.

[R31Nismoid]

I did have, that was the RB25...

Just about finished RB26 install now.

And for most applications discussed here, he's right.

my rb25 made 304rwhp with nismo 740cc injectors at about 38% duty.

[RRob]

340kw or 454hp made with 740's on about 66% duty cycle. This wason a 3l too.
