Hello everyone,

Stock pulley usually between 6-8 psi + 1/2 psi free for PP. Now factor in plus/minus 1-2 psi for aftercooler? I'm assuming by "stock" pulley you are referring to 3.60?

yo; I'm asuming that you have a stock pullie on your sq v2 blower at 6800 rpm you should see 12 psi take away 1-2 psi for the aftercooler,but if you bought the cooler from vortech they would have giving you a smaller pullie 3.48 or 3.33 as the cooler will take up some boost to push through this smaller pullie will bring you back up to 12 psi,remember the vs spins a little faster than the v1 as the set up ratio is 3.45 to 1 on v1 and 3.54 o 1 on v2 superchargers.
