its not the v2 you have to worry about. im not too familiar with the new edge mustangs, i know more about the new models but i wouldnt go past a 12psi pulley. thats about as far as i can take it on mine, and the newer ones have a bit stronger internals ( forged rods from the factory). like i said before the SC itself can make about 20psi. if your running anywhere near that you might want to upgrade the internals. but 12 and under your safe, just make sure to get a good dyno tune. its key.
