居然还要做到这一步：曲轴偷轻

赛车，，就是要做到极致啊！

其实难点不在这儿~关键是动平衡没有地方做啊~gochinway06；）

功效就自己看吧：

Castillo then drilled out the oil passage plugs in the crank to facilitate cleaning and tapped the holes so screw in hex plugs could be used. This is much safer and more secure than the stock pressed in plugs. The journal oil holes were chamfered and teardropped to create a reservoir for oil from the main bearing feed to improve oil flow to the rod bearings. The bob weights of the same weight as our rods and pistons were bolted to the crank and the whole assembly was dynamically balanced. As a final step all of the cranks journals were micro polished to reduce friction and help improve bearing life. Although all of these steps are not needed in a low buck engine, they are not particularly expensive either.

配合轻量化锻造连杆和活塞吧，要轻就一起轻，才和谐啊……

这个不便宜。。。。要是给我换最后的决定应该还是换引擎交划算些。chinway12tiger
