That's weird...the DUO 10.5 is supposed to have sintered rotors. Check out their website and see the specs...
About the 13.5, you do have to increase timing on them. Start from a 5.0FDR and work your way down a tooth at a time and increase timing...they should be fast.
Felix LAw reported the 10.5BL Trinity DUO was really fast, used by Tony Padilla, if I'm not mistaken...Maybe someone can ask him to comment here about the motor and what gearing and timing he'd recommend to get them be fast.
