Can't go lower than 10.1, car simply do not allow smaller pinions (10.1 = 16T) (unless I dremel the motor mounting holes).
Gonna confirm it's the blue wire (thx Marcos) with Charlie@Novak, then cut it. Will mount a big fan I have lying on my table together with the two coolcanfans I'm using now to the motor to keep it as cool as possible, but at least it wont thermal. That'll total the fan count to 5; 1 big and two smaller ones for the motor and two smaller ones for the speedo. Sounds like a hurricane when booting it up, but who cares
if you are running the MI2 EC you can run a 120 spur ,its very close to bottom out but I ran mine like that in asphalt for 5 months with no problems i ran a 120/20 for a 10.8 fdr and no thermal issues, you might want to plug the fan directly into the battery pack and will push out more air,
