[Thrusted Vector]

How much fuel pressure should we have at 12 psi on the Apex turbo?

Do I have to change the full presure from 4psi to run 16 psi at 1000 ft runs on the cpr turbo?THANKS

fuel pressure

I have never hooke a gauge up to mine when under boost but I think it will go up Quite a bit beause the fuel pressure regulator will have pressure on it and that will close it off to a certain extent... The mc-xpress 310 kit comes with a extra fuel pump for more volume

For some reason, I think the fuel pressure is suppose to be 3-4 psi higher than the boost psi. I,ve been investigating pretty hard about turbos and I read that somewhere other than here.

I'v found that anywhere from 2 - 4 psi over boost is good

I run at 2.5 psi
