Vivek came back for some small upgrades and one of them was a pulley swap on the Vortech blower. You can see his last post here.
It’s hard to tell much change from over a year and a half ago but besides the smaller blower pulley we added an idler pulley on the front side of the blower bracket for more belt wrap which will help with more consistent boost pressures. We went from the 3.33″ pulley to 3.12″ pulley on the blower.
376 whp for 34 whp more over peak and 313 torque up from 287 torque.
