DD= daily driven, meaning it is still 100% streetable and not just a weekend ride. Aboot 13-14psi on the stock internals is consdered safe for DD use and track abuse. You can get more than 11psi out of a procharger though, and id personally rather be supercharged for reliability reasons. But turbos are nice.....

Your lucky, you purchased one of the best engines ford has ever made. I know it doesnt produce a lot of power out the door, but add some boost, nitrous, and internals, and that car WILL LAST FOREVER.
