26101, Is 12:1 ratio of FMU is too rich for our engine?

How much of fuel do we need each 1 lb psi of boost does our engine need anyways? They say 8:1 ratio is the right ratio, is that right?

Well it all depends on your current set up...What turbo system do you have? Stock fuel injectors? I know on my HRC S16G setup, its a 5:1 ratio. This means for every pound of boost, you need to raise the fuel pressure by 5 psi. This is only for the HRC setup though..and for up to 6 or 7 psi.

Who are they?
Question is absolutely dependant on what turbo and setup, etc. Easy answer - you want enough fuel so that you are running around 12.0:1 a/f at full boost.
