Magna Charger - Magna Charged
Want more boost? Stepping up from a 3.40-inch pulley to a 3.20-inch one netted us an additional pound of boost. Even that mere 1 pound produced an increase of 8 hp at 6,100 rpm and around 20 lb-ft at 3,100 rpm. That's 1,000 rpm less than with the previous pulley. Not only that, but the entire torque curve was improved with the smaller pulley, showing much more grunt down low, which is where you want it. Best of all, Magna Charger claims this blower will support most SBC applications up to 600 hp. |  | |
