I know you guys probably all know this one, and I am sorry for asking but I could not find a good straight foward answer to this. My 84 T Type is bone stock. What it the factory or should I say from the factory amount of boost for this car? Is it like 6psi? I am just wondering? And what would you say is safe for the street? My Ranger would blow head gaskets at around 8 psi now intercooled I can do around 15psi and drive all day long 23psi at the track then it just goes down from there. Damn timing belt!!!
