Ok well i swapped my cam to a 306 and blah blah blah...anyways i ran datamaster and the reason it's cutting out up top is my injectors are 118% so i'm guessing i need bigger ones...well my brother has two Syclone's and stock syclone injector's are 32lbs! Can i use these...i know i'll need to get 8 but as soon as he puts the 70lber's in the syclone i can get 8 of them! What i need to know is will these be fine and what do i need to change in my tune to accomidate for these new larger injectors?!!? thanks!


btw...i'm gonna put a walbro 255lph in there too!

 

What you need to find out is they these flow @ 43.5psi (or whatever your fuel pressure is). Injectors flow at different lbs/hr depending on the fuel pressure. Ex: stock injectors may have a higher flow rating (30lb/hr I believe), but that is at 60psi, but when on an Lt1 they are only 26lb/hr). There's a formula to figure it out, but it's late and I'm going to sleep, but you can do a search or someone else will chime in w/ the formula.

 

As cheap as injectors are these days, why not just buy a new set instead of using 12 year old injectors. Check the GP forum, there's a few sales going on right now.
