    start at 52 (static) like jerry said.. but it will depend on how many rpm's your planning to turn

    a skat 14/20 ~21 should get you to 85-8600 rpm's thru the stock exit nozzle wich would be my choice.

    if you want to stick to the dyna, you want to repitch it to 15 on the leading edge and again the trailing is gonna depend on the rpm's your shooting for.
