just a thought, the stock injectors of a civic is 240cc @ 38psi at idle. what are the dsm injectors rated at? 450cc @ _ _ psi ?

Not sure, but running them on my B-Series. . . with about a 240 hp setup, they were not running very much duty cycle at all. They are pretty large.

Im looking to push them to 300-320whp on my sohc, I dont mind upping the fuel pressure a little

I'm running 50psi idle on my B18C1

260WHP @6.5 PSI

CroteTurbo

Mine are at 50psi fuel pres = 295 whp@10.5 psi near 90% Duty cycle

USDM 4G VTEC

weird
i got 43psi
at 10 psi, and pig rich (under 10 AFR) on stock fuel pump and i am on 58% duty cycle

295whp 90% duty and 50psi? Doesnt sound even close to right

im runnin mine at 38psi idle with the walbro 255lph at 7 psi with -39% cor on the afc. im thinkin of gettin some prelude 320cc injectors so it doesnt **** with my map tables too much, ideas?

most wont like what i was running, but i ran 70psi at idle, i had a WALBRO 255 high pressure fuel pump, so i figured it could handle it..... it can! but i was also running AEM EMS. at 15psi i was at a 70% injector duty cycle. this was on dsm 450 black tops. i had full controll over them, no problems at all!

what setup would cause use to run them taht high, even with the ems being able to control them to limit the flow?
