Greetings Christopher, I imagine that you talk about the wheel of inertia that goes between the engine and the box, if it can be clear, but in a synchronous car you can lose to put it so "torque" in a time of starting since now the inertia that carries the engine is lower (by the light of the aluminum), obviously raises the rpm in empty but when apply These flyers are calculated for each motor model and its function is to make the engine turn constant to put it in某种程度上,启动时没有方向盘将是以第三速度启动,您会感觉到每个活塞都在拉盒子的力量。问候。
