I haven't tried to extrapolate the max torque. Anything over the predicted maximum is a gift, and I have refrained from looking at it too closely :)

 Thanks Kang & Bill.
 I see where I got mixed up on the Max torque formula.
 Using Kang's 5/99 example, the adjustment for Max turns is simple. Just multiply the calculated Max turns by 1.07. Even I can figure that one out!
 How do you calculate the adjusted Max. Torque for 5/99? I assume it is not a simple linear relationship.

   Those are also the formulas I use.

   The formulas I use:
 
 
 max turns = motor_length * 45.67*SQRT (motor_length / motor_weight )
 
 
 
 max torque =( motor_weight / motor_length / 0.11)^1.5
 
 
 These are used only as guidelines as different batches behave differently.
 
 
 For my 7/99, the max turns is very accurate. For my 5/99, I can get a 7% more turns.

 Bill,
 I think the formula you are using for Max Torque is:
 Max Torque =((motor weight in grams/0.11)^1.5)
 Am I correct? What formula are you using for Max turns?
 Thanks,
 Gary H

   For 2 grams(net) x 20" the formulas I use show 2880 turns max and .87 in-oz max.
