For a 120ft straight, gearing between 6.8 and 7.4 FDR (depending on track / motor combo / ESC settings) is the typical range.

If your temps are coming off at 120F, you can try the following:
45 Boost
18 Turbo
0.1 delay
2 ramp (you can try 1 if the motor temps stay low to see if it likes the timing sooner)
16K for the end RPM, and somewhere between 3000-4000 for the start.
Start at 7.2FDR and see how it responds.

On another note, the option timing boards the Speed Passion sells really wakes up these motors for 1/10th TC use. I am running a 30 degree board (set to 24 degrees) and it really helped get more rip out of the corners due to the mechanical timing advance.

Let us know how those settings work out. Remember to check the motor temps after a couple minutes with the new settings.

EDIT: Just noted that you were 13.5, not 17.5 which is what the settings above are for...... Gearing more like 7.4 - 7.8 FDR for 13.5
45 Boost
18 Turbo
0.1 delay
2 ramp (you can try 1 if the motor temps stay low to see if it likes the timing sooner)
19K for the end RPM, and somewhere between 4000-4500 for the start.

Sorry about that.
