got a problem and need some help. i was recently running 310 injectors and an 8:1 fmu on my turbo setup with everything you see on my setup below. the car boosted strong but ran very rich and like crap. now, i blew my 310 injectors and put back my original 240's and the car runs great. but now i am afraid i will run lean when i boost. can i boost safely with the 8:1 disc or should i go with a 10:1 or even a 12:1? or will i be fine with an 8:1 but richen up with my apexi v-afc up high? by the way i am boosting 7psi on this setup. please give me some feedback.

 

Well~ I'd go with a 12:1 BUT Only for a little bit while you're saving for bigger injectors...The stockers won't last long with that amount of stress

 

i aM asking if i could run safely with my 8:1 disc and 240's, can anyone help me withn this?

 

no one here is able to help me

 

Let me tell you from my experience. I have a b16 with a drag 3 kit, which i believe comes with a 10:1 vortech FMU. I was running my stock injectors and a stock fuel pressure. I ended up blowing the high pressure fuel line that goes from the fuel filter to the fuel rail. I was talking to the guys at honda and they said they are only made to withstand 100psi or so of fuel pressure. So if that tells you anything may you should stay where you are at and keep the boost turned down. And oh yeah i was only boosting at like 8psi.

 

right on....too much pressure for stock oem issued parts.
mainly injectors
