    Looking to get more torque out my Briggs without risk of blow up or snapping a shaft...

    3HP

    3600 rpm

    4.4 torque rating.

    3/4 shaft

    Trans/pulley system pre setup:

    Clutch Small pulley: 3.5 inches

    Large drive pulley: 15inches (whizzer sheave.)

    Belt estimated size by calculator:

    Pull centers: 20 inches

    SP X LP x PC = 70.1 BELT SIZE.

    ESTIMATED STOCK MPH PRODUCTION ON 32.3 CALCULATED


    "Low end torque needed for hills?"
