got a qwestion about the vortech sfmu i noticed that it comes with a few disks for adjustablity. but is it prebuilt with a disk in there alreeady? if so what? and is it safe to run on a stock motor with about 8 lbs?

 

with stock injectors you'll need to run 12:1 or 10:1 depending on a few other things

 

What disk would be good for size 310 injectors for 8psi of boost? Would 12:1 or 10:1 still be ok?

 

8:1 is what I run with 310's
