No, 'timing acc' does not determine the maximum RPM the motor will reach on track. It determines the 'Boost End RPM' at which full boost timing will have been reached. The car still continue to accelerate after this point, even if no further timing (turbo) is added. The acceleration may or may not be fairly linear; without the increasing boost effect the acceleration would drop off and be very non-linear. With the boost, it will be closer to linear than without it.
Drag and weight do not affect the calculations, although they will of course affect how quickly the car accelerates on track.
