Default Motor timing in boosted class

If a motor like D3/D3.5 comes with 30 deg built in motor timing, wouldn't it be logical to dial it to -20 or less in the endbell and add the timing in the ESC??


Is there something wrong with this reasoning??

Nope - turning down the enbell timing and running more ESC timing helps keep the motor cooler - not sure about going down as far as -20 though

Unless you have better boost know-how than most, I would just leave the motor static timing at whatever it states as being'0' on the endbell, neither advanced or retarded, (this is the motors 'natural' timing, about 30 degrees for Trinity stuff) and boost from there. I have tried retarding timing on the endbell past this 'zero' point and boosting more and all I got was more heat and a slower car, it seems that after a certain point less timing is bad for the system as well.

Thanks for chiming in, I was ready to turn down the endbell timing and crank up the ESC timing without any guilt.

Did you turn up the timing in the ESC the same degrees you lowered it on the endbell??

Can you go a lot higher on the ESC boost, than just the amount you reduce on the motor. On my tekin, I tried 55 degree boost and another 20 degree turbo, with the motor reduced to 20 degrees (was 48 unboosted). Even with all this timing, the motor ran cooler. I also geared down from my unboosted gearing.
The result was more torque and a lot more top speed.

+1 geairng down and adding timing to gain top speed works fantastic. If you get a chance, continue to practice with different mechanical timing setting to know motor limits and best performance settings.

No.

D 3.5 13.5 motor.

Personally, I turn my castle speedo to MAX 50 degrees of timing.
Never mess with the speedo timing.
Run -8 degrees of can timing and gear it to the track.

Temp motor and slowly add timing if under 160F

Found starting -8 to -5 degrees was more efficient as lap times did'nt fall off at the end of the race.
