I am not sure if this is correct or not, but does the 05 Mustang GT have forged pistons or not. For some reason I thought I read on this site that they are not forged (???). If they are not forged does anyone know the limitation on boost (HP increase) that can be added from a supercharger. Just curious, and if they are not forged is there a way we can get the word out to ford to make them forged. If I remember correctly didn't the 5.0L HO engines have forged pistons. Thanks in advance.......
