13.5 12th scale timing;
Try a roll-out around 2.3 - 2.6, no timing or very little in the motor, most from the ESC.

13.5 WGT timing;
Try a roll-out around 2.2 - 2.5, no timing or very little in the motor, most from the ESC.

13.5 WGT no-timing;
Try a roll-out around 3.0 - 3.4, Full to almost full timing in the motor.

Of course this depends on track size and layout flow. Go up on roll-out for a large flowing track, and down for small tight track. These are starting points, your driving style may require a different range. Always temp motor at 3min when making gearing and ESC timing changes so you don't burn-up your motor.
