Thread: FPR going out?

So the question is to get a nismo FPR and run the 370s at 4bar or go with sti injectors at 3 bar?

Well, I'm guessing you are running a T25. In which case, 370's at 4 bar are enough for you. T25 won't make enough power to max those out at that pressure. Plus, at 4 bar you will get better atomization and therefore better fuel mileage.

Planning on getting a GT2560R quite soon aswell. Still a vote for the 370s at 4bar?

They are good to around 300 horsepower (320ish if you live at higher altitude). So if you plan on going higher then that I'd suggest stepping up a size.

I dont know bout that, mine were maxed out at 283whp ( running FPR @ 4 bar)

OP, I would get some 555 injectors and run them at 4 bar
And no, I you shouldnt have damaged anything running at 12.6 AFR for a little while...

Maybe they were a bit dirty then? I was near 300 horsepower on my T28 and they weren't maxed out yet. But they were damn close.

But I agree with Beto. 555 + 4 Bar. That's what I'm switching my injectors to as well.

maybe they were, but I dont think so...

Yeah, its always to have a safe margin to play with fuel and not be maxing injectors out...

I don't get how I would be maxing out 370s at 12psi unless one of them is clogged?

How much power are you making? 370's max out at 250 hp. You were probably hitting that at around 15 psi.

but I am still leaning out when I hit full boost at 12psi, its not as bad but it goes to 11.8-12.2 AFR.
