Fuel injector size help!
Fuel injector size help! The motor is pretty much in my sig but Ill go over it again:
Stock LS1 block, .030 over
Stock crank, Eagle rods, JE thick to pistons with 4cc reliefs
Ported Heads with 2.055 int and 1.6 exh valves shaved .020, claimed flow of neer 300 cfm @ .600, Comp 921 kit
Comp Cams custom grind cam: .622 lift int and exh 258 int and 270 exh @ .050
Wiend Intake
Pacesetter race headers, no EGR, No AIR,
Most likely a 78mm ported TB or the BBK 80 mm
Granatelli/walbro 225 pump
It will run a 4K stall and probably run to around 7K
I may also be getting a set of Jessel 1.75 rockers soon
I have Dyno 2k and engine analyzer pro, both estimate around 500 crank hp and the machine shop said thru my auto they would expect with a nitrous tune it will make around 430 hp at the ground
Ive been told everything from 36 to 55# so any insite would be greatly appriciated

get 60# injectors and not have to worry about it for a long time. 60#'s are about as big as injector as you can get while staying high impedence. This way if you want to go bigger you have room and motron 60# injectos can be had for just over $400 new.
don;t buy injectors twice in a year....like i did lol i run the 60#'s now.

injector size I believe Slow Trap is correct. Your 42# should be adequate for 600 plus horsepower if run NA. If you run them in a boosted mode they should easily support around 500 horsepower. The 60# Mototron injectors are nice pieces and very precise but would not seem necessary if you already have a decent set of 42#.
