How much boost can I safely run on 270 injectors? I have a 12:1 fmu and a 255lph intank and a NOS inline. Can I run 8-10 psi? I have a built b18c1 block with 9:5:1.

 

its not how much they can handle its how long till they hit full duty cycle and your check engine light comes on with a code 16.

 

get a 10:1 disk and ill say 12-13psi max

 

I just plan to run it this way to race a few people tonight and maybe at the the track in two weeks. I'm getting my 550's an hondata installed as soon as I can find someone good within 750 miles who can do it. I'm running stock injectors but was gonna put in some spare 270's tonight. Would it be better to run the 240's with a 12:1 fmu?

 

yeh it will work but its going to be rich u may spray a little smoke out

 

Would it just be better to run the stock injectors? Will I be ok as long as I keep my inj duty cycle under 85%-90%. Will the270's really make my car run that rich? I was just gonna use them for a little extra saftey.

 

im running 550cc x4 boosting @ 6psi
no smokes
