請問Xray T2 08 5.5r spur 48p/84T 齒比

小弟依家用17s 行 8.4 gear ratio. 是否適合?. 重有冇得快0的而又唔overload.
麻煩師兄指教下.

For 5.5R, reference fdr is 7.5-8.5
So you can increase your pinion size a little bit more.  Its better to check the temperature of your motor after 2-3 minutes.  If temp < 65C, then you are ok.  If temp > 70C, your gearing is wrong.

gearing, track size, outside temp, driving style, car setup ... all will affect motor temperature.

咩摩打先? 8.4 好慢O者, 唔會拖死個摩打. 8.5R 摩打用6.8-7.3既ratio 啦
