Yes. Don't be afraid to try the 3 dot, and go out to something in the 3.4s. Caveat to that is that you'll want to run a heatsink/fan. I know at my home track, the fast guys are running in the 3.4s with a fan and are doing fine, even with ambient temps on the track around 100F, and a surface temp over 110F.

Remember, just because you CAN gear it hot and still survive doesn't mean that's the best place. Straight line speed is only useful for the long straight and the sweepers. Depending on the track, it might be FASTER to gear in the low 4s (if the infield is large and highly technical) and sacrafice straight line speed for better pull off of the corners. Choose your passing zones carefully, and shoot a tighter line through ALL of the corners with the torque to pull out ahead and through the next one, and you'll be so far ahead through the infield that their straight line speed won't matter.

Of course, if your set up is working awesome and you are all but traction rolling, gear to the moon and pass 'em all everywhere!

Blinky is a game that's won and lost in the corners in the infield. You won't have enough torque with the gear ratios to pull it off if you blow the line, and the more speed that you can carry into/through the corner (assuming that the set up on your car can handle it), the better off you'll be.

In standard classes we have to use std rotor.

Has anyone tried using this motor with a Speed Passion GT 2.1 Prostock with latest timing software?

I borrowed a motor from a friend last night, soldered it up in the TC, revved it up on the bench and all was fine. Ramped up with timing as expected. Placed it on the track, pulled the trigger, the car jerked a second, moved forward at 1/4 speed when using full throttle. The ESC started flashing a green light. From the troubleshooting guide it says the sensors are not being read. If you turn off\on the ESC it revves up again when holding the car as expected. Put it on the track same thing starts moving forward but with no timing and the green light is flashing again.

This motor works perfectly fine, the sensor wire is fine (works a Ballistic without a problem).

This exact same scenario happened with a 17.5 Murf Dog motor.

Any Ideas? I'm posting this same message on the Speed Passion thread.

Thanks,
Brent

What sort of temps is it safe to go up to with these X12 motors in 17.5 and 13.5 touring cars ??

I believe that the instruction sheet says 210F. X12s like it hot!

210 f that's 98 celsius, this is hot, too hot, for a motor to last I would say 80 celsius 176 f, I get between 76 and 80 in average and this is fine.

X12's are not even close to smoking at 210.

Ok, even if 210 is fine, it does not mean that is is faster, on top, you could have thermal on speedo and/or damaged cells, it is a chain of connection and if one does not do his job properly, the chain is broken...

It is better to play safe and I can garantee you that at 80 degree celsius, my speed is top.

I found this information in a 12th scale thread:

4-dot = 27.5°
3-dot = 32.5°
2-dot = 37.5°
1-dot = 42.5°
0-dot = 47.5°
You read the timing with the dots facing you.
