    Show MorePerformance Ratios
    Uses a smaller performance crank pulley and larger water pump pulley to increase horsepower by reducing accessory drag, with typical gains of 12-15 horsepower at the rear wheels.

    Mid Performance Ratios
    Uses performance crank pulley to decrease accessory speed to increase horsepower and a high water flow water pump pulley to maintain cooling.

    High Water Flow Ratios
    Increases cooling by speeding up water flow and fan speed. This helps at critical low speed driving where most overheating occurs.
