how far will 42# lsj injectors get me??? and the racetronix fuel pump??? how far will that get me??? hp wise and boost wise... i dont want to lean out. or clip. i want to my fuel system to be comfortable while im pushing 15psi... at anything over 250whp.
Not to 250. I'm at like 65% idc with 60's on a 2.8 pulley with the mp62. which would be like 80 ish on 42's and be maxing them out almost.

lsj injectors aren't 42#.
the stage 1 or 2 lsj injectors are. sorry i didnt specify that, can anyone help me get an idea on injectors and pump i might need to be able to hit close to 300. but dd at aroun 225-250whp. at a comfortable idc??
i want big enough injectors and a good pump that wont try to hard to hit 300whp. il be running around 12-18 psi also if that helps. but i need expert opinions.
You need bigger injectors for 300 hp.

The pump is good for about 600 HP according to racetronix website. What you really need are the injectors. I would do some more research in that area if i were you.
Whats up people?
i hit 243hp on a dynodynamics so im almost to 300 and i have ford 42# injectors and they are keeping good afrs

I'm running 42lb/hr injectors and the racetronix fuel pump. When Ryan tunned my car I was in the low 30'S for duty cycle and numbers are in my sig. I'm on a 3.0 pulley making 9-10psi with an MP62 blower.
so now ive got mixed opinions... will 42#'s get me to 300whp??? or not??? some say sure some say no? and a side note i have a 2002 fuel rail and a 2003 fuel rail. wich injectors should i get wich clips? wich harnesses? and wich rail should i use i need opinions.
Well the people that say the 42's wont work....are they on a stock pump or stock with a pusher pump? My injectors came off my friends Ion R/L I just had to grind the blocks off my 04 rail and slot the tabs, and it worked perfectly.
but are those injectors good for my goal??

^^^ exactly, fuel pressure is a factor too.
I really need to buy a fuel pressure gauge and put a real fpr in my return line.

mine was stock fuel pump with 42# ford green tops and i put down 234 whp on a dyno dynamics dyno which is like 280ish on a dyno jet and i was leaning out around 5k and up it leaned out to about 12.5-13.0afr so im pretty sure i need to put my walbro intank in lol but to be honest i would buy some 60# injectors just and i only say that because your gonna want more so just save yourself time and money and just buy them once
