Hello,
I was wondering what is the max psi you can run on a for 5.0. I was told that 18 PSi is the max. I'm wondering because I want to run around 20 psi 5.0 im building for my mustang. while im at it. which should I go with a supercharger or a Twin Turbo system. It is a 5.0 efi out of a 1985 couger and is going to go into a 1987 mustang lx.
