im only going to be boosting 7psi for now on my y8. which ratio do i need to get with my fmu. thanks

 

what injectors? Stock? 12:1 will work

 

yea they are stock. so i use 12:1? thanks for the quick reply.

 

no problem, be sure you use an INLINE pump


Rob

 

What makes you say that?

 

here i go AGAIN
an fmu requires high amounts of fuel pressure to properly operate in its designed fashion. An intank pump wont provide enough fuel pressure to adequetly operate the FMU. I know there are going to be people poping up now saying " i have been running an intank and 12:1 fmu for 87 years with no problems" well i just want you to know that you cant allways hear detonation. I hate this conversation, flame me if you must.......

Rob

 

Are you just talking about a stock in-tank or are you also including high-flow in-tanks?

 

high flow inline

 

high flow or stock intank. doesnt matter. not enough fuel pressure. GET AN INLINE.

 

if u dont know what an inline fuel pump is... then dont put a turbo on your car cuz u might blow up your motor.

 

12:1 should work fine for you @ 7 psi.

 

Glad to see people are starting to agree with me


Rob

 

lol who listens anyways.???
people are still boosting with a 12:1 stock injectors and that famous Walbro.

 

some peoples children
