TT01e Pinion/Spur hop-up

[Pri5tt01e]

Hi, im looking to get a bit more speed out of my stock TT01 (steel bearings fitted):

540 Torque Tuned Motor
TBLE-02 S ESC
Core RC 4012 Servo (4Kg)

I have already got the aluminum prop shaft ordered.

The stock car is currently running 61T Spur & 19T Pinion.

Without changing the motor what Spur/Pinion would you recommended for a bit more straight line speed?

 

Thanks

Torque tuned motor can handle quite a high gear ratio. I think when I raced one in the Iconic Cup I was up as as high as 55/27.

I have Google’s and Googled it... but can Someone sum up the gear ratios specifically examples around Tamiya TT01 kits  

 

What’s the difference in higher/lower/mixed pinion to spur ratio? I.e someone has also recommend 55/25

would that be slower than 55/27 but maybe more reliable?better on engine? 
 

thanks!!!!

Larger pinion and/or smaller spur will give more top speed, less acceleration, and be a heavier load on the motor and electrics.

55/25 will be a little easier on the motor.
