View Full Version : N* Ifr

im looking to upgrade fuel injectors and need to know the flow rate of the N*'s? i did a quick search and didnt find it...

Why are you upgrading? Higher flow injectors will hurt performance unless you've done something drastic (cams, boost...)

They are 23.5#/hr stock

boost, but not on a N*. i have access to free ones, just needed to know ifr to see if it would be worthwhile to go through the hassel of retrofit, which it isnt. they only flow 1lb more than what i have now on my 3400.

gotcha. generally speaking you want to find something with more displacement( or horsepower rather) per cylinder...

3400/6 = 4600/8, so it makes sense they'd be the same size

I think the 4.6L cobra (supercharged) engiens use 42#/hr

i dont think those will be easily fitted. leaning more towards the pontiac gtp's 36#s, thanks for your help.

sometimes i wish i still had my 87 deville....lol
