It's advertised as 23,000 rpm and 170 g-cm torque.
Maurizio had this to say about it:
"Except for the endbell, now moulded in one single piece vs the previous two pieces unit, the motor is exactly the same as before. Same magnets, case, winding, armature, carbons.
It must be considered that the previous orange-ish endbell motor was wrongly specified at 21.5K, whereas it was 23K instead. "
"The improvement should be a more uniform production, not a change in performance, so I think the old orange endbells V12/3 and the new V12/4 should be allowed to race together.
We've made several tests and there is no significant performance change."
"The Skoal Bandit car will still have the V12/3 motor, the Camel 962 the new one."
