hi, i have an option of getting 15 or 20 tooth pulleys. the car came with 20 teeth on the pulley, but what advantage and disadvantages are there? i assume maybe a little better torque/acceleration with 15?

less teeth=more speed but less accel

actually, its less teeth = quicker take off but less top end and more teeth = slower take off but more top end. Im going to assume that its the pulleys that drive the diffs. If thats the case, then 15 will = less top end and 20 will = more top end.

it depends on where its small,er if tis smaller at the diff then its more top sped but less accel
