Ok, I thought I had my problem iron'd out with 8psi and fuel... but i guess not..

At WOT 5k and above the air/fuel meter goes completely red...

I have upped the fields a little and a lot to try and increase the fuel... thing is I should be ok at 8psi with what I have according to a lot of people.

I have an in-tank bbk fuel pump and a fuel pressure gauge hooked up inside the car. The fuel pressure is high and doesn't drop...

What the heck is the problem?

Mind you I don't get on it every day above 5k, so my boost fix is still there.. but what happens when an SS rolls up on me?? I'm sure I will need the power above 5k to take em down!!!

 

whats your fuel setup?

 

What injectors you running and what's your fuel pressure under boost?

 

sounds like you need injectors,. why don't you richen up with the fields some more?

What is your setup.

 

yes what injectors, what FMU ratio, and is that BBK pump high pressure? With stock injectors on 8 pai you should be somewhere around 120 psi with a 10:1 disk. I dont think those intanks can go that high. I recommend some 310's, lower the rise rate to 8:1 and get a Bosch fuel pump.

 

I think you're on the right track.. those intank pumps cant flow at those high fuel pressures. If you are running an FMU you need an inline pump.
