| to let anyone know who is thinking about a 19 percent reduction pulley one came into my deaer the other day and the way they explained it to me was that it was literally eating the supercharger from the inside out. this was after about 5,000 on that pulley i believe, 17% is the safest one while aslo giving u good hp and torque gains, 19 is a litle risky on a non upgrade supercharger |
