棉花糖牌宝马教程三十二：水冷，油冷和under drive pulley
本帖最后由 mianhuatang 于 2011-1-4 21:30 编辑棉花糖牌宝马教程三十二：水冷，油冷和under drive pulley
新年开车去了一次vegas，总共竟然用掉了10天之多，剩下不多的假期还好能够用在改装上。（顺便说一句，vegas不好玩，除了酒店奢侈豪华以外，没有内涵，not my cup of tea。连号称最好看得fantasy and Jubilee也就很一般。。。最后顺便大峡谷了一次，野营，登山才好玩）。
这次的主题是水冷，油冷和under drive pulley，因为得到赞助商的新年礼物，所以虽然以前把水冷做掉了，但是礼物的装备实在是太诱人了，把原来服役时间不长的装备都换掉了。
芝加哥天气太冷，不多打字，直接上图。首先是under drive pulley。中文是什么不知道。就是轻一点，直径大一点的pulley，能有效的降低水泵，助力转向泵和发电机的转速，一般而言可以节约5-7马力。这套东西是我从ebay上找到的，只要$50。。。

发电机pulley新老对比，周长加大了，pulley转速就会低，然后有效的降低parasitic drag，所以能节约动力http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7164.jpg
最难装上去的就是发电机pulley，需要用24mm的冲击扳手把老的pulley搞下来，然后再装上去。装的过程中把发电机架子给搞断掉了，所以就顺手换了一个发电机。$200调到下水道了去了。。。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7154.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7157.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7171.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7180.jpg
接下来是水冷。首先是thermostathousing。原来的塑料housing时间长了容易破裂，这次用了吕的，顺便powder coat一下，防止氧化，另外把原来的水温sensor重新定位到这里，保证读取温度信号更直接。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/DSC03896.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/DSC03913.jpg
这个是鼎鼎大名的Stewart水泵。适用于全系列的宝马，我的赞助商提供的，经过多年的全美国无数用户测试，能有效的提升水循环量，降低温度。我因为用了under drive pulley，所以就更需要high performance的水泵了。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_0994.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_0995.jpg
因为把机械风扇给删除了，所以使用一个反向螺帽防止水泵顶端锈蚀，顺便也好看一些。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_1005.jpg
没有机械风扇就要使用电子风扇，慷慨的赞助商提供了16寸的直叶风扇。虽然噪音要比普通的弯叶风扇大很多，但是同样转速下出风量多很多，非常适合赛道使用。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7076.jpg
一些安装过程的图片http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7087.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7094.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7092.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7098.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7114.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7117.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7124.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7135.jpg
顺手把暖气空调最后的管线也给拆了，就需要一个bypass。自己动手早得bypasshttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7147.jpg
最后也是最重要的油冷。Setrab扩散器就不用多说了吧。。。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3209.jpg
用2根长长的1/4”all thread给固定好。看上去完全像是原厂的风格。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3213.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3217.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3220.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3221.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3230.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_3228.jpg
拆掉原来的oilfilter housing，改用欧版的housing，直接提供机油冷却出入口。没有使用我自己的设计的原因是，想保留另外一个设计，就不展开了。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/DSC03110.jpg
我自己设计加工的转接口，比原厂的密封性能好，而且使用了AN管线，保证性能。http://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/DSC03120.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/DSC03117.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7174.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7177.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7211.jpghttp://i293.photobucket.com/albums/mm80/ningshao/pulley%20and%20cooling/IMG_7215.jpg 沙发 太牛了 期待与支持棉花糖写出更多好文章 学习了....
