More speed please

[steady_eddie]

I wanted to try and increase the top speed of this set-up

Ansmann X2C
Reedy 450 ESC
Turnigy saddle lipo's 7.4v
EasyRun 4000kv 8.5T Victory Motor
20T Gear on the motor

I'm thinking the best way may be to simply put a bigger gear on the motor? Maybe a 22T or 24T or would that be no good?

This is for the Coventry Astro track with quite a long straight - the car is not slow but once upto speed you are flat out and then have to kind-of wait for the next corner, I was thinking if the car could keep accelerating it would be a bit more entertaining - not sure if it would actually reduce the lap times though.

I know people seem to use motors with less turns for more speed and those motors will have less torque but wouldn't that be the same as putting a bigger gear on a motor with more turns? Anyway I think gears would be cheaper that motors to experiment a bit.
