Max torque is a moving number - it changes with exhaust system setup used .
I have two different ZDZ80's and on same tuned full length pipe one turns 300 more rpm - the stock one 7000-the modified 7300
same Mejzlic prop so torque obviously moved up.
The mod engine also turns 26x12 ZM, 6450 on the ground and 7400 in level flight in a H9Edge . on big JMB can ,NOT tuned pipe.
I really don't know if any 100's can match it . Maybe they can -but have not seen one .
Note the 1.25 thick hub on the 26x12 -
Onboard tach verifies real in flight rpm.
