What's the word with pop-off valves?
I have every thing for my setup waiting in the floor of the garage, then my friend mentions a pop-off valve. I have an unopened wastegate actuator witha 6psi spring. I also have a btm and a bov. Do I really need a pop-off valve? I don't want to grenade my engine cause I don't have a spare any more. I need advice. Thanks

A pop-off valve is a real part so don't give your buddy too hard of a time because it can be a good thing to have, but it's not neccissary. Basically its a pressure relief valve that incase you overboost, it'll blow before you're headgasket or motor does. Let's say you're running 5psi of boost. You set your pop-off valve to 6 or 7 and if a vaccum/pressure line comes off the wastegate this valve will save your car from achieve insane boost levels which obviously has a good chance of saving the headgasket, or your piston rings. I think HKS makes an adjustable one...I'm not sure who else does tho.
